What are the effects of Ritalin?

Ritalin is a stimulant drug that doctors frequently prescribe to treat people with attention deficit hyperactivity disorder (ADHD), among other conditions. It has proven effective over many years but has some mild and potentially serious effects.

Keep reading to learn more about the mild and severe side effects of Ritalin and its interactions with other substances.

What is Ritalin?

Ritalin is a prescription-only, synthetic medication that people often use to treat ADHD. Ritalin is a brand-name. It contains the active chemical methylphenidate.

Ritalin is a central nervous system (CNS) stimulant. It works by stimulating the brain chemicals dopamine and norepinephrine, chemicals associated with control and attention.

Dopamine also has strong associations with pleasure and reward. Norepinephrine mobilizes the brain and body to get ready for action and is involved in the fight or flight response.


The U.S. Food and Drug Administration (FDA) have approved Ritalin to treat ADHD in pediatric patients 6 years and older. The symptoms of ADHD include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity.

The FDA also approve Ritalin to treat adult narcolepsy.

Off-label indications, not approved by the FDA, include using Ritalin to treat major depressive disorder and terminal cancer.

Methylphenidate is prone to misuse, just like other stimulants.

Its ability to improve concentration means some people use it to boost cognitive ability.

Ritalin is available as a tablet that a person can take orally and as a patch that allows absorption of the medication through the skin.

Side effects

For most people prescribed Ritalin, the drug helps them concentrate and gain control over their actions. This can help with day-to-day functioning at school or in their job.

The package insert for methylphenidate provides information covering every aspect of the drug’s use.

It lists many warnings and potential adverse reactions from using the drug. However, everyone reacts to medicines differently. Some people experience very few, if any, side effects from taking Ritalin.

Mild side effects

Ritalin is short-acting, so the drug does not stay in the body for an extended period. This means that any side effects usually occur while Ritalin is in a person’s system.

Some mild side effects of Ritalin are:

  • agitation
  • an energized feeling
  • a headache
  • difficulty sleeping
  • moodiness
  • anxiety
  • nausea
  • reduced appetite

{lease note that this is not a comprehensive list of all the side effects. Before taking Ritalin, a person should talk with their doctor about possible side effects and whether Ritalin is the right choice for them.

For people with cardiac problems, a history of seizures, or those prone to anxiety, Ritalin might make matters worse.

A person who receives a prescription for Ritalin should make regular appointments to see their doctor every few months. The doctor can ask about any adverse reactions, check the person’s blood pressure, and make adjustments to the medication if necessary.

Serious side effects

Some severe side effects of Ritalin include:

  • cardiovascular reactions, including sudden death, stroke, and heart attack
  • increased blood pressure
  • increased heart rate (tachycardia)
  • psychiatric adverse reactions, including worsening of a pre-existing psychiatric condition
  • development of new psychotic or manic symptoms
  • sustained and sometimes painful erections in males
  • poor circulation, including Raynaud’s phenomenon
  • long-term suppression of growth and weight loss in pediatric patients
  • potential for abuse and dependence*

*Please note that Ritalin carries a Black Box Warning that reads:

“WARNING: ABUSE AND DEPENDENCE CNS stimulants, including Ritalin and Ritalin-SR, other methylphenidate-containing products, and amphetamines, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy.”

Please note that this is not a comprehensive list of all the serious side effects. Before taking Ritalin, a person should talk with their doctor about possible side effects and whether Ritalin is the right choice for them.

Ritalin can suppress growth in children and adolescents, particularly in the first few years of taking the drug. A doctor will monitor the height and weight of young people taking Ritalin.

has found that circulation problems, including Raynaud’s disease, have been associated with using methylphenidate. If a person experiences numbness in the fingers or toes, they should contact a doctor immediately.

Stimulant drugs like Ritalin can be addictive and, if misused, can have long-term mental health consequences. Prescribed doses are very unlikely to lead to dependency.

Taking more than the prescribed dose of Ritalin can also put pressure on the heart, nervous system, and immune system, leading to long-term health complications.

In rare cases, Ritalin might trigger an allergic reaction. The most common signs to look out for include:

  • itching
  • nasal congestion, or rhinitis
  • hives (itchy red spots on the skin)
  • rash
  • watery or itchy eyes
  • scratchy throat

Recreational use

Ritalin is not approved for recreational use, and it is illegal to take or possess the substance without a prescription.

If a person is using Ritalin recreationally, or more often than their doctor prescribes, this could be a sign of abuse and dependence.

Some people do take Ritalin recreationally for its stimulating effect. It can give the user a temporary feeling of alertness and energy. It can also lead them to feel overconfident and remove inhibitions, which could lead to risky behavior.

Very high doses of Ritalin can lead to:

  • delusions or hallucinations
  • shakiness or twitching
  • paranoia
  • panic attacks
  • seizures
  • confusion

A person should seek medical attention if they have any of these symptoms.

Long-term effects

A pharmaceutical company first marketed methylphenidate as Ritalin in . Since then, it has proven safe for most people as a treatment for ADHD and other conditions.

One looked at studies into the long-term behavioral effects associated with Ritalin use. The review found no reliable evidence that Ritalin affects behavior long-term.

Interactions with Ritalin

When a person takes Ritalin alongside other medications, it can be dangerous. According to the package insert, Ritalin interacts with the following drugs:

  • Monoamine Oxidase Inhibitors (MAOIs): MAOIs include selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, and methylene blue. People should not take Ritalin alongside these medications as it can cause severe and sometimes fatal side effects.
  • Antihypertensive drugs: These include diuretics, calcium channel blockers, angiotensin-converting-enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), beta-blockers, and centrally acting alpha-2 receptor agonists.
  • Certain anesthetics: Anesthetics that cause interactions include halothane, isoflurane, enflurane, desflurane, and sevoflurane.

Other possible interactions include:

  • acid reflux drugs, such as antacids, H2 blockers, and proton pump inhibitors
  • blood pressure drugs, such as losartan, valsartan, irbesartan, enalapril, lisinopril, hydrochlorothiazide, and furosemide
  • antipsychotics, such as chlorpromazine and haloperidol
  • seizure medications, such as phenytoin and phenobarbital
  • warfarin
  • caffeine
  • cold or allergy medicines

Before taking Ritalin, a person should tell their doctor or pharmacist about other medications they are taking. The doctor or pharmacist can advise about possible interactions with Ritalin.

When to see a doctor

Anyone who receives a prescription for Ritalin will need to regularly visit a doctor or other healthcare professional to review their medication needs. As Ritalin is a tightly controlled medication, a person will need a new prescription from a doctor each time.

If the medication loses its effects or has undesirable side effects, a person should tell their doctor. The doctor may adjust the amount of medicine they prescribe. A person taking Ritalin should never change their own dose and must consult a doctor first.

Males should call or their local emergency service if they have an erection that lasts more than 4 hours or becomes painful. This can be a sign of a serious problem that needs immediate treatment.

If a person has numbness in the fingers or toes or changes in skin sensitivity or skin color, they should call or contact their local emergency service.

Chest pain, changes in heartbeat, or breathing difficulties can also be dangerous, and a person should call or their local emergency service immediately.


Doctors have prescribed Ritalin to treat conditions such as ADHD and narcolepsy for decades.

It affects people in different ways but is generally safe when used as directed by a doctor.

Ritalin has the potential to be addictive at any dose and can have some serious adverse effects.

Effects of Ritalin on the Body

Ritalin is one of the common treatment options used for attention deficit hyperactivity disorder (ADHD).

Although this stimulant can improve symptoms of ADHD, it can also cause some side effects. Ritalin can be misused, and that comes with the risk of more serious side effects throughout the body. It should only be used with medical supervision.

When you first start taking Ritalin for ADHD, the side effects are usually temporary. See your doctor if any symptoms worsen or last beyond a few days.

Find out more about the various symptoms and side effects that you might be at risk for while using Ritalin.

The effects of Ritalin on the body

Ritalin (methylphenidate) is a nervous system stimulant that’s commonly used to treat ADHD in adults and children.

It’s a brand-name prescription medication that targets dopamine and norepinephrine in the brain to reduce common ADHD symptoms.

Though Ritalin is a stimulant, when used in ADHD treatment, it may help with concentration, fidgeting, attention, and listening skills.

According to the , about million U.S. children ages 2 to 17 (or percent of children) were diagnosed with ADHD as of

Ritalin is just one form of treatment for ADHD. It’s often complemented with behavioral therapy.

Ritalin is sometimes used to treat narcolepsy, a sleep disorder.

As with all stimulants, this medication is a federally controlled substance. It can be misused, which comes with the risk of serious side effects.

Ritalin should only be used with medical supervision. Your doctor will likely see you every few months to make sure the medication is working as it should.

Even if you take Ritalin correctly and don’t misuse it, it can carry the risk for side effects.

Central nervous system

Ritalin influences both dopamine and norepinephrine activity in your brain.

Dopamine is a neurotransmitter that affects pleasure, movement, and attention span. Norepinephrine is a stimulant.

Ritalin increases the action of these neurotransmitters by blocking their reabsorption into your brain’s neurons. The levels of these chemicals increase slowly, so your doctor will start you on the lowest possible dose and increase it in small increments, if necessary.

Ritalin may make it easier for you to concentrate, be less fidgety, and gain control of your actions. You may also find it easier to listen and focus at your job or in school.

If you’re already prone to anxiety or agitation, or have an existing psychotic disorder, Ritalin may worsen these symptoms.

If you have a history of seizures, this medication may cause more seizures.

Some people taking Ritalin experience blurred vision or other changes to eyesight. Other potential side effects include:

  • headache
  • trouble sleeping
  • irritability
  • moodiness
  • nervousness
  • increased blood pressure
  • racing heartbeat, in rare cases

This medication can temporarily slow a child’s growth, especially in the first two years of taking it. That’s why your child’s doctor will keep an eye on their height.

Your child’s doctor may suggest taking a break from the medication. This is often done during the summer months. This can encourage growth, and also allows them to see how your child does without taking it.

Ritalin, like other central nervous system stimulants, may be habit-forming. If you take a large dose, the quick rise in dopamine can produce a temporary feeling of euphoria.

Taking Ritalin in high doses or for a long time can be habit-forming. If you stop taking it abruptly, you may experience withdrawal.

Symptoms of withdrawal include sleep problems, fatigue, and depression. It’s better to taper off slowly and under a doctor’s care.

When misused, stimulants like Ritalin can cause feelings of paranoia and hostility.

Very high doses can lead to:

  • shakiness or severe twitching
  • mood changes
  • confusion
  • delusions or hallucinations
  • seizures

If you have any of these symptoms, seek medical attention immediately.

Circulatory system

Ritalin can cause circulation problems. Your fingers and toes may feel cold and painful, and your skin may turn blue or red.

Use of Ritalin is linked to peripheral vascular disease, including Raynaud’s disease. If you take Ritalin and experience circulatory problems, tell your doctor.

Stimulants can also raise your body temperature, blood pressure, and heart rate. You may feel jittery and irritable. That’s usually not a problem in the short term, but you should have regular exams to check your heart rate and blood pressure.

Stimulants should be taken with caution if you have pre-existing blood pressure or heart problems. Ritalin may increase your risk of heart attack and stroke.

Rare cases of sudden death have occurred in people who have structural heart abnormalities.

Misusing stimulants by crushing pills and injecting them can lead to blocked blood vessels. An overdose can lead to dangerously high blood pressure or irregular heartbeat.

High doses can also lead to life-threatening complications such as heart failure, seizures, and significantly high body temperature.

Digestive system

Ritalin can reduce appetite in some people. Other side effects include stomachache and nausea.

Misusing this drug can also cause vomiting, abdominal pain, and diarrhea.

Over time, misuse of Ritalin can lead to malnutrition and related health problems. It may also lead unintentional weight loss.

Respiratory system

When taken as prescribed, Ritalin doesn’t generally cause a problem with the respiratory system.

At first, though, Ritalin can increase your breathing slightly and also open up your airways. Such effects are temporary and will go away after a few days once your body gets used to a new prescription or dosage.

However, very high doses or long-term misuse can cause irregular breathing. Breathing problems should always be considered a medical emergency.

Muscular and skeletal systems

When you first start taking Ritalin, you might experience improved mood, and almost a sense of euphoria. This can translate to everyday physical activities being easier to accomplish.

In the long term, Ritalin can cause musculoskeletal complications when misused or taken in too large of doses.

Such cases can lead to muscle pain and weakness, as well as joint pain.

Reproductive system

Males who take Ritalin may experience painful and prolonged erections. When this occurs, it’s usually after prolonged Ritalin use, or after your dose was increased.

It’s rare, but it sometimes requires medical intervention.

What are the side effects and risks of Ritalin?

Doctors often prescribe Ritalin for the treatment of ADHD and sometimes for narcolepsy. Ritalin can cause various side effects and also has the potential for misuse and addiction.

Ritalin is the brand name for methylphenidate, a medication that stimulates the production of dopamine and norepinephrine in the brain. Experts believe that these two chemicals play an important role in attention deficit hyperactivity disorder (ADHD).

Some people misuse Ritalin because of the stimulant effect it has on the brain.

In this article, we look at the side effects of Ritalin along with its uses, dosage, and precautions. We also discuss Ritalin addiction, whether long-term use is harmful, and when to see a doctor.

Side effects

As with all medications, Ritalin can cause side effects in some people. The following table lists the possible side effects of Ritalin:

Very commonCommonRare
stomach upsetrestlessness and feeling jitterystroke
dry mouthheadachevisual disturbances
upper respiratory infectionsdrowsinessblurred vision
decreased appetitedizzinessabnormal liver function
uncontrolled, involuntary movementsdrug-induced skin diseases
coughmuscle cramps
abdominal painsevere allergic reactions
vomitingblood disorders
rapid heartbeat
increased blood pressure
hair loss
excessive sweating
joint pain


The Food and Drug Administration (FDA) have approved Ritalin for the treatment of ADHD in children and adults.

ADHD is a behavioral disorder that affects a person’s ability to focus and pay attention. Other symptoms can include impulsivity and hyperactivity.

Doctors also prescribe Ritalin as a second-line treatment option for people with narcolepsy.

Narcolepsy is a rare, neurological disorder that affects a person’s sleeping and waking patterns. People may feel tired throughout the day and can be prone to suddenly falling asleep in the middle of daily activities.

Doctors may sometimes also prescribe Ritalin off-label to help reduce fatigue in people with cancer or to treat symptoms of depression in older adults.

Some people misuse Ritalin for its stimulant and memory effects. In the United States, the federal government classify Ritalin as a Schedule II substance, which means that it has a high risk of misuse and can cause severe psychological and physical dependence.


Ritalin is available as:

  • Immediate-release tablets, which release into a person’s body immediately after ingesting.
  • Extended-release tablets, which gradually release into a person’s body after ingestion.
  • A patch that a person applies to their skin.

The following table lists the available strengths in milligrams (mg) of methylphenidate products.

Drug nameFormulationRelease typeStrength
Ritalinoralimmediate release5 mg, 10 mg, 20 mg
Ritalin-SRoralextended release20 mg
Ritalin-LAoralextended release10 mg, 20 mg, 30 mg, 40 mg
Daytranapatchextended release10 mg, 15 mg, 20 mg, 30 mg


According to the manufacturer’s leaflet, children aged 6 years and older can start on a dose of 5 mg, twice daily, of immediate-release Ritalin. A doctor may increase the dose by 5 mg or 10 mg every week until they achieve the desired effect.

The average dose for adults is between 20 mg and 30 mg.

Doctors may switch people from immediate-release tablets to extended-release tablets. This allows the person to take fewer doses per day but still get the same effect from the medication.

A person can wear a Daytrana patch on the skin for a maximum of 9 hours. The starting dose is usually 10 mg, although some people may need a higher dose.

The maximum dose of Ritalin for both children and adults is 60 mg per day.


Ritalin is a second-line option for the treatment of narcolepsy. Doctors may prescribe Ritalin for people with narcolepsy if other drug options have been unsuccessful.

Typical doses of Ritalin for narcolepsy are between .


Anyone who has an allergy to Ritalin or medications containing methylphenidate should not take Ritalin.

People taking monoamine oxidase inhibitor (MAOI) antidepressants should also avoid Ritalin because the two drugs interact with each other. The manufacturer recommends that people stop taking MAOIs 14 days before starting Ritalin.

Ritalin can cause small increases in blood pressure and heart rate, so doctors will exercise caution when prescribing this medication to individuals with hypertension and tachycardia.

There have been reports of sudden death in children with heart conditions who were taking Ritalin.

Similarly, people with structural abnormalities of the heart should not take Ritalin.

Before a doctor prescribes Ritalin, they will assess the person for preexisting psychotic or bipolar disorders, as Ritalin can worsen symptoms of these conditions.

In rare cases, Ritalin can cause or worsen Raynaud phenomenon. Raynaud phenomenon is a condition where the blood vessels in the fingers and toes restrict blood flow in response to cold temperatures and stress.

When people are taking Ritalin, they should monitor their fingers and toes in cold temperatures and when under stress and report any changes to their doctor.

Ritalin addiction

At the correct dose, Ritalin is not addictive. However, people who misuse this drug or take very high doses of Ritalin are at risk of physical dependence and addiction.

Is long-term use harmful?

Doctors prescribe Ritalin for the treatment of people with ADHD or narcolepsy, both of which are chronic conditions. There have been no clinical trials to evaluate the effectiveness of Ritalin for more than 4 weeks of treatment, however.

Doctors who prescribe Ritalin for longer than 4 weeks will assess the long-term effectiveness and safety of this medication for each person.

Researchers concerned about the safety and effectiveness of Ritalin for long-term use have designed the study.

This study is assessing the effectiveness of Ritalin for treating ADHD in children and adolescents and the effect of the drug on:

  • growth and development
  • cardiovascular health
  • psychiatric health
  • neurological health

ADDUCE is a large, ongoing 2-year study, and the results are not yet available. Further information and updates are available on the study website.

Children and adolescents sometimes take Ritalin for more than 2 years. Future studies are necessary to assess the safety and efficacy of Ritalin for longer treatment durations.

When to see a doctor

People can speak to their doctor about any severe or concerning side effects they experience while taking Ritalin. A doctor may recommend adjusting the dosage or changing to a different treatment.

Ritalin can cause long-term growth problems in children, so doctors will usually monitor this closely. In adults taking Ritalin, healthcare professionals may regularly assess blood pressure and heart rate, particularly in those with preexisting cardiovascular conditions.

People who experience symptoms of psychotic or bipolar disorders while taking Ritalin should seek medical attention. Stimulant medications can cause psychotic symptoms, even in individuals without a history of mental disorders.

Rarely, Ritalin can cause painful and prolonged erections in males. Anyone who experiences this side effect should seek immediate medical attention.


Ritalin is generally a safe and effective medication for the short-term treatment of ADHD and narcolepsy. However, Ritalin can cause a range of side effects, and its long-term safety and effectiveness are still under investigation.

Ongoing follow-ups of both children and adults taking Ritalin to ensure the benefits outweigh the risks are an essential part of the treatment that doctors will give.

Doctors usually prescribe Ritalin at the lowest effective dose to minimize side effects and the potential for addiction.

Ritalin may not be safe for everyone. People should report any severe or concerning side effects to their doctor.

Side Effects of the Drug Ritalin


pronounced as (meth'' il fen' i date)

Methylphenidate can be habit-forming. Do not take a larger dose, take it more often, take it for a longer time, or take it in a different way than prescribed by your doctor. If you take too much methylphenidate, you may find that the medication no longer controls your symptoms, you may feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior. Tell your doctor if you drink or have ever drunk large amounts of alcohol, use or have ever used street drugs, or have overused prescription medications.

Do not stop taking methylphenidate without talking to your doctor, especially if you have overused the medication. Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may develop severe depression if you suddenly stop taking methylphenidate after overusing it. Your doctor may need to monitor you carefully after you stop taking methylphenidate, even if you have not overused the medication, because your symptoms may worsen when treatment is stopped.

Do not sell, give away, or let anyone else take your medication. Selling or giving away methylphenidate may harm others and is against the law. Store methylphenidate in a safe place so no one else can take it accidentally or on purpose. Keep track of how much medication is left so you will know if any is missing.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with methylphenidate and each time you get more medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucmhtm) or the manufacturer's website to obtain the Medication Guide.

Methylphenidate is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children. Methylphenidate (Methylin) is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). Methylphenidate is in a class of medications called central nervous system (CNS) stimulants. It works by changing the amounts of certain natural substances in the brain.

Methylphenidate comes as an immediate-release tablet, a chewable tablet, a solution (liquid), a long-acting (extended-release) suspension (liquid), an intermediate-acting (extended-release) tablet, a long-acting (extended-release) capsule, a long-acting (extended-release) tablet, a long-acting (extended-release) chewable tablet, and a long-acting (extended-release) orally disintegrating tablet (tablet that dissolves quickly in the mouth). The long-acting tablet, orally disintegrating tablets, and capsules supply some medication right away and release the remaining amount as a steady dose of medication over a longer time. All of these forms of methylphenidate are taken by mouth. The regular tablets, chewable tablets (Methylin), and solution (Methylin) are usually taken two to three times a day by adults and twice a day by children, preferably 35 to 40 minutes before meals. Adults who are taking three doses should take the last dose before pm, so that the medication will not cause difficulty in falling asleep or staying asleep. The intermediate-acting tablets are usually taken once or twice a day, in the morning and sometimes in the early afternoon 30 to 45 minutes before a meal. The long-acting capsule (Metadate CD) is usually taken once a day before breakfast; the long-acting tablet (Concerta), long-acting chewable tablet (Quillichew ER), long-acting suspension (Quillivant XR), and long-acting capsules (Aptensio XR, Ritalin LA) are usually taken once a day in the morning with or without food. The long-acting suspension (Quillivant XR) will begin to work sooner if it is taken with food. The long-acting orally disintegrating tablet (Cotempla XR-ODT) and the long-acting capsule (Adhansia XR) is usually taken once daily in the morning and should be taken consistently, either always with food or always without food. The long-acting capsule (Jornay PM) is usually taken once daily in the evening (between pm and pm),and should be taken consistently, at the same time every evening and either always with food or always without food.

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methylphenidate exactly as directed.

Do not try to push the extended-release orally disintegrating tablet (Cotempla XR-ODT) through the blister pack foil. Instead, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it in your mouth. The tablet will quickly dissolve and can be swallowed with saliva; no water is needed to swallow the tablet.

You should thoroughly chew the immediate-release chewable tablets and then drink a full glass (at least 8 ounces [ milliliters]) of water or other liquid. If you take the immediate-release chewable tablet without enough liquid, the tablet may swell and block your throat and may cause you to choke. If you have chest pain, vomiting, or trouble swallowing or breathing after taking the chewable tablet, you should call your doctor or get emergency medical treatment immediately.

Swallow the intermediate-acting and long-acting tablets and capsules whole; do not split, chew, or crush them. However, if you cannot swallow the long-acting capsules (Aptensio XR, Jornay PM, Metadate CD, Ritalin LA), you may carefully open the capsules and sprinkle the entire contents on a tablespoon of cool or room temperature applesauce, or for long-acting capsules (Adhansia XR), you may open the capsules and sprinkle the entire contents on a tablespoon of applesauce or yogurt. Swallow (without chewing) this mixture immediately after preparation (within 10 minutes if taking Adhansia XR) and then drink a glass of water to make sure you have swallowed all of the medicine. Do not store the mixture for future use.

If you are taking the long-acting chewable tablet (Quillichew ER) and your doctor has told you to take part of the tablet to get the correct amount of your dose, break the 20 mg or 30 mg long-acting chewable tablet carefully along the lines that have been scored into it. However, the 40 mg long-acting chewable tablet is not scored and cannot be divided or split.

If you are taking the long-acting suspension (Quillivant XR), follow these steps to measure the dose:

  1. Remove the bottle of medication and dosing dispenser from the box. Check to be sure that the bottle contains liquid medication. Call your pharmacist and do not use the medication if the bottle contains powder or if there is no dosing dispenser in the box.
  2. Shake the bottle up and down for at least 10 seconds to mix the medication evenly.
  3. Remove the bottle cap. Check that the bottle adapter has been inserted into top of the bottle.
  4. If the bottle adapter has not been inserted into the top of the bottle, insert it by placing the bottom of the adapter into the opening of the bottle and pressing down firmly on it with your thumb. Call your pharmacist if the box does not contain a bottle adapter. Do not remove the bottle adapter from the bottle once it is inserted.
  5. Insert the tip of the dosing dispenser into the bottle adapter and push the plunger all the way down.
  6. Turn the bottle upside down.
  7. Pull the plunger back to withdraw the amount of oral suspension prescribed by your doctor. If you are not sure how to correctly measure the dose your doctor has prescribed, ask your doctor or pharmacist.
  8. Remove the dosing dispenser and slowly squirt the oral suspension directly into your mouth or your child's mouth.
  9. Replace the cap on the bottle and close tightly.
  10. Clean the dosing dispenser after each use by placing it in the dishwasher or by rinsing with tap water.

Your doctor may start you on a low dose of methylphenidate and gradually increase your dose, not more often than once every week.

Your condition should improve during your treatment. Call your doctor if your symptoms worsen at any time during your treatment or do not improve after 1 month.

Your doctor may tell you to stop taking methylphenidate from time to time to see if the medication is still needed. Follow these directions carefully.

Some methylphenidate products may not be able to be substituted for another. Ask your pharmacist if you have any questions about the type of methylphenidate product your doctor has prescribed.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking methylphenidate,

  • tell your doctor and pharmacist if you are allergic to methylphenidate, to any other medications, aspirin (if taking Adhansia XR), tartrazine dye (a yellow dye in some processed foods and medications; if taking Adhansia XR), or any of the ingredients in the methylphenidate product you are taking. Ask your doctor or check the Medication Guide for a list of the ingredients.
  • tell your doctor if you are taking monoamine oxidase (MAO) inhibitors, including isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or have stopped taking them during the past 14 days. Your doctor will probably tell you not to take methylphenidate until at least 14 days have passed since you last took an MAO inhibitor.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); antidepressants such as clomipramine (Anafranil), desipramine (Norpramin), and imipramine (Tofranil); decongestants (cough and cold medications); medications for heartburn or ulcers such as esomeprazole (Nexium, in Vimovo), famotidine (Pepcid), omeprazole (Prilosec, in Zegerid), or pantoprazole (Protonix); medications for high blood pressure; medications for seizures such as phenobarbital, phenytoin (Dilantin, Phenytek), and primidone (Mysoline); methyldopa; selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem, in Symbyax, others), fluvoxamine (Luvox), paroxetine (Brisdelle, Paxil, Pexeva), and sertraline (Zoloft); sodium bicarbonate (Arm and Hammer Baking Soda, Soda Mint); and venlafaxine (Effexor). If you are taking Ritalin LA, also tell your doctor if you take antacids or medications for heartburn or ulcers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you or anyone in your family has or has ever had Tourette's syndrome (a condition characterized by the need to perform repeated motions or to repeat sounds or words), facial or motor tics (repeated uncontrollable movements), or verbal tics (repetition of sounds or words that is hard to control). Also tell your doctor if you have glaucoma (increased pressure in the eye that may cause vision loss), an overactive thyroid gland, or feelings of anxiety, tension, or agitation. Your doctor will probably tell you not to take methylphenidate if you have any of these conditions.
  • tell your doctor if anyone in your family has or has ever had an irregular heartbeat or has died suddenly. Also tell your doctor if you have recently had a heart attack and if you have or have ever had a heart defect, high blood pressure, an irregular heartbeat, heart or blood vessel disease, hardening of the arteries, cardiomyopathy (thickening of the heart muscle), or other heart problems. Your doctor will probably tell you not to take methylphenidate if you have a heart condition or if there is a high risk that you may develop a heart condition.
  • tell your doctor if you or anyone in your family has or has ever had depression, bipolar disorder (mood that changes from depressed to abnormally excited), mania (frenzied, abnormally excited mood), or has thought about or attempted suicide. Also tell your doctor if you have or ever have had seizures, an abnormal electroencephalogram (EEG; a test that measures electrical activity in the brain), circulation problems in your fingers or toes, or mental illness. If you are taking the long-acting tablet (Concerta), tell your doctor if you have a narrowing or blockage of your digestive system.
  • tell your doctor if you are pregnant or plan to become pregnant. If you become pregnant while taking methylphenidate, call your doctor.
  • tell your doctor if you are breastfeeding or plan to breastfeed. If you are breastfeeding while taking methylphenidate your doctor may tell you to watch your baby closely for unusual agitation, difficulty sleeping, poor appetite, or weight loss.
  • talk to your doctor about the risks and benefits of taking methylphenidate if you are 65 years of age or older. Older adults should not usually take methylphenidate because it is not as safe as other medications that can be used to treat the same condition.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking methylphenidate.
  • be aware that you should not drink alcoholic beverages while taking the long-acting chewable tablet (Quillichew ER), the long-acting orally disintegrating tablet (Cotempla® XR-ODT), or the long-acting capsule (Adhansia XR or Jornay PM).
  • if you have phenylketonuria (PKU, an inherited condition in which a special diet must be followed to prevent mental retardation), you should know that the immediate-release and long-acting chewable tablets contain aspartame that forms phenylalanine.
  • you should know that methylphenidate should be used as part of a total treatment program for ADHD, which may include counseling and special education. Make sure to follow all of your doctor's and/or therapist's instructions.

Take the missed dose as soon as you remember it. Talk to your doctor or pharmacist about how late in the day you should take a missed dose of your medication so that it will not cause difficulty in falling asleep or staying asleep. However, if it is almost time for your next scheduled dose, skip the missed dose and continue your regular dosing schedule. If you are taking the long-acting capsule (Jornay PM), take the missed dose as soon as you remember it that night. However, if it is already the next morning, skip the missed dose of the long-acting capsule (Jornay PM) and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from light and excess heat and moisture (not in the bathroom). Store methylphenidate in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many tablets or capsules or how much liquid is left so you will know if any medication is missing.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Keep all appointments with your doctor and the laboratory. Your doctor may check your blood pressure and heart rate and order certain lab tests to check your response to methylphenidate.

This prescription is not refillable. Be sure to schedule appointments with your doctor on a regular basis so that you do not run out of medication.

Suddenly she stopped flickering her sweethearts there. Her body began to sulk in convulsions. Her boots in boots bent over, and she, pressing her palms between her feet, slid onto the floor. I noticed that one stocking had completely detached itself from the cutters that supported it and slid down to the very top of the boot.

Without leaving her eyes, I, backing away, retreated to the stairs on the second floor and quietly climbed up.
