What is Methylphenidate?

Methylphenidate is a prescription medicine used to treat attention-deficit hyperactivity disorder, or ADHD. Put simply, this medicine changes the levels of certain natural chemicals in your brain. These changes help you keep your attention in one place and control impulsive or hasty actions.

Medicines like this belong to a group of drugs known as central nervous system stimulants. They help calm busy minds and make it easier to concentrate on school, work, or daily tasks.

Keep in mind that doctors sometimes prescribe this medicine for other medical conditions as well. If you have questions about why your doctor chose this treatment, feel free to ask them for clarification during your next visit.

Things to Tell Your Doctor Before Starting This Medicine

Before you or your child start taking this medicine, sharing your complete health history with your doctor is extremely important. Certain health conditions can interact with stimulants or make them unsafe to use.

Please make sure to let your doctor know if you or anyone in your family has any of the following health concerns:

Health Condition or Category What to Look Out For
Mental Health Issues Anxiety, panic attacks, other mental illnesses, or thoughts of self-harm in you or family members.
Heart and Blood Pressure High blood pressure, heart disease, heart defects, blocked blood vessels, or past strokes.
Blood Circulation Problems Issues with blood flow reaching your fingers and toes, causing coldness or pain.
Other Medical Conditions Glaucoma, liver disease, seizures, thyroid problems, or phenylketonuria.
Habits and Personal History Past drug or alcohol abuse, motor tics, or Tourette's syndrome in yourself or family.
Allergies Any past allergic reactions to methylphenidate, other drugs, foods, or dyes.
Special Circumstances Pregnancy, trying to get pregnant, or currently breastfeeding an infant.

How to Use This Medicine Correctly

Because this is a chewable tablet, you must chew it thoroughly in your mouth before swallowing it down. Do not swallow the tablet whole before it is completely chewed and broken down. After chewing and swallowing, drink a full glass of water.

Here are some helpful daily tips for taking your medicine:

  • Before meals: Unless your doctor gives you different instructions, take this medicine about 30 to 45 minutes before eating.
  • At the same time: Try to take your medicine at the exact same time every single day to keep a steady routine.
  • Avoid late doses: Take your final dose of the day at least four to six hours before bedtime so it does not interfere with your sleep.
  • Follow your dose: Never take a larger amount or take doses more often than what your doctor prescribes for you.

Important: This medicine belongs strictly to you. Never share your medicine with anyone else under any circumstances. Sharing prescription stimulants is both dangerous and illegal.

What to Do If You Miss a Dose

If you forget to take your medicine on time, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose completely and continue with your normal schedule.

Never take two doses at the same time to make up for a missed one. Double dosing can cause unwanted and dangerous side effects.

What to Do If You Take Too Much

If you suspect you or your child took more medicine than prescribed, act quickly. Call emergency services right away or contact your local poison control center for immediate guidance.

Potential Drug Interactions

Tell your doctor about every single product you take, including vitamins, herbal supplements, and over-the-counter remedies. Certain drugs can cause serious reactions when mixed with methylphenidate.

Medicines to Avoid Completely with Methylphenidate
MAO Inhibitors: Medicines used for depression, such as carbex, eldepryl, marplan, nardil, and parnate.
Lithium: A medicine commonly prescribed for specific mental health conditions.
Procarbazine: A medicine used in certain cancer treatments.
Other Stimulants: Any other drugs meant to boost focus, suppress appetite, or keep you awake.
Medicines That Require Careful Monitoring by Your Doctor
Blood pressure drugs, blood thinners like warfarin, atomoxetine, and high amounts of caffeine.
Seizure medicines such as carbamazepine, phenobarbital, and phenytoin.
Certain medicines for depression, anxiety, common colds, or severe allergies.

Things to Keep in Mind While Taking This Medicine

Managing your treatment safely involves regular check-ins and paying close attention to how your body responds. Keep these helpful tips in mind:

  • Regular checkups: Visit your doctor regularly so they can monitor your overall progress. For growing children, doctors will track height and weight carefully.
  • Focus and alertness: This medicine can affect your alertness or reaction times. Avoid driving cars, riding bicycles, or operating heavy machinery until you know how the medicine affects you personally.
  • Loss of appetite: A drop in appetite is common when first starting this medicine. Try eating smaller, frequent meals throughout the day instead of three large ones. Talk to your doctor if this persists.
  • Important note for males: If you experience an erection that lasts longer than four hours or causes pain, seek medical help right away. Ignoring this rare condition can lead to permanent damage.
  • Finger and toe changes: Watch your fingers and toes for unusual numbness, pain, skin color changes from pale to blue or red, or unusual sensitivity to cold temperatures. Report these signs to your doctor promptly.

Side Effects of Methylphenidate

Like all medicines, methylphenidate can cause side effects, though not everyone experiences them. Knowing what to watch for helps keep you safe.

When to Seek Emergency Help

Call 911 (US/Canada) or 999 (UK), or go to your nearest Emergency Department right away if you or your child experience severe chest pain, fainting, sudden weakness, signs of a severe allergic reaction, or thoughts of harming yourself.

How to Store and Dispose of Your Medicine

Keeping your medicine safe and secure is a crucial part of managing your treatment responsibly. Follow these storage guidelines:

  • Keep away from children: Store your medicine in a secure location completely out of reach of children and family pets. Accidental ingestion of stimulant medicines can be fatal.
  • Prevent misuse: Because these tablets are sought after by others, keep them in a safe spot protected from theft or misuse.
  • Storage conditions: Keep the container tightly closed at room temperature, away from excess moisture, heat, and direct sunlight.
  • Safe disposal: Do not throw leftover or expired pills into household trash cans or flush them down the toilet. Mix them with used coffee grounds or cat litter, seal them in a bag, and discard them safely according to local take-back programs.
