 What is the most important information I should know about Concerta?

   Use caution when driving, operating machinery, or performing other hazardous activities. Concerta may cause dizziness, drowsiness, blurred vision, or impair your ability to concentrate. If you experience dizziness, drowsiness, blurred vision, or impaired concentration, avoid these activities.

   Do not crush, chew, or break the sustained- or extended-release formulations of methylphenidate (Ritalin SR, Ritalin LA, Metadate ER, Metadate CD, Methylin ER, Concerta).

Do not save the mixture for later use. The capsule contents should be swallowed whole and not crushed or chewed.
