The dosage of Methylphenidate should be individualised according to your or your child's clinical needs and responses. Your doctor would initially start a low dose, and then gradually increase to the dose that works best for you or your child.

Most methylphenidate preparations can be taken with or without food, except for Medikinet® MR. Medikinet® MR must be taken with or after food as it may affect its absorption.

If you or your child is taking Ritalin® LA, Medikinet® MR or Concerta® ER, it must not be crushed or chewed.

For Ritalin® LA and Medikinet® MR, the capsule may be opened and the capsule contents sprinkled onto a small amount (tablespoon) of room-temperature/cold food (e.g. applesauce or yoghurt), and must be administered immediately. It should not be stored for future use.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and take only the regularly scheduled dose. Do not take a double dose to make up for the missed one.
