Concerta Dosage

The dose of Concerta (Methylphenidate) extended release needs to be individualized according to the needs of the person taking the medication. The dose is usually started low and increased gradually to the dose that works best for the person.

For people who are not currently taking Concerta (Methylphenidate), the usual starting dose is 18 mg once daily in the morning with or without food.

For people currently taking another form of Concerta (Methylphenidate), the starting dose depends on the current dose being taken. Doses above 72 mg daily are not recommended.

Swallow Concerta (Methylphenidate) whole with water or other liquids. Do not crush, chew, or split the tablets. Concerta (Methylphenidate) is designed to be released into the body over time. When the tablet is broken, the medication is released into the body faster than it should be and may cause serious side effects.

You may notice the Concerta (Methylphenidate) extended release tablet in your stool. If your child is on Concerta (Methylphenidate), you may notice the tablet in your child's stool. This is normal and occurs because the tablet does not completely dissolve after all the medication has been released in the body.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones above, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Concerta (Methylphenidate) exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. Avoid taking Concerta (Methylphenidate) late in the day, as it may cause difficulty sleeping. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Concerta (Methylphenidate) at room temperature, protect it from moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
