How should I take Methylin?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Methylin may be habit-forming. Misuse can cause addiction, overdose, or death. Keep the medication where others cannot get to it. Selling or giving away Methylin is against the law.

Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the medicine your doctor prescribes.

Most brands of methylphenidate are taken 1 to 3 times during the day. Jornay PM is for use only in the evening. Do not use this medicine more often than prescribed.

Take with a full glass of water.

You may take Methylin with or without food, but take it the same way each time. Some brands of methylphenidate need to be taken 30 to 45 minutes before a meal.

Swallow the extended-release capsule or tablet whole and do not crush, chew, break, or open it.

If you cannot swallow an extended-release capsule whole, open it and mix the medicine with soft food such as applesauce or yogurt. Swallow the mixture right away without chewing.

Part of an extended release tablet shell may appear in your stool but this will not make the medicine less effective.

You must chew the chewable tablet before you swallow it.

Shake the oral suspension (liquid) for at least 10 seconds. Measure liquid medicine (solution or suspension) with the supplied measuring device (not a kitchen spoon).

Remove an orally disintegrating tablet from the package with dry hands only when you are ready to use the medicine. Allow the orally disintegrating tablet to dissolve in your mouth without chewing.

Tell your doctor if you have a planned surgery.

Your doctor will need to check your progress on a regular basis and you may need medical tests to check your heart function. Tell any doctor who treats you that you are using this medicine.

Your treatment may also include counseling or other treatments.

Do not keep leftover medicine. Just one dose can cause death in someone using it accidentally or improperly. Ask your pharmacist about a drug take-back program. You may also mix the leftover medicine with cat litter or coffee grounds in a sealed plastic bag and throw the bag in the trash.

Store tightly closed in the original container at room temperature, away from moisture, heat, and light. Keep your medicine in a place where no one can use it improperly.
