What is Concerta: Uses, Warnings & Interactions

Take your Concerta as directed. The dose may need to be changed several times to reach the most effective dose.

Please read the Medication Guide that comes with the medicine.

Take Concerta tablets in the morning.

Take only one tablet each day.

Swallow the tablet whole with water or other liquid. Do not crush, break, or chew it.

An empty tablet covering may pass into the stools. This is normal and nothing to worry about.

Store Concerta in a tightly closed container or in the reusable travel case at room temperature. Keep the tablets protected from humidity.

Ask the prescriber or a pharmacist what to do if a Concerta dose is missed.

Concerta doses should be taken in the morning. As a general rule, a missed dose of Concerta can be taken anytime in the morning.

Taking a missed dose later in the day risks sleeping problems at night.
