Methylin ER Oral Warning

Misuse or abuse of methylphenidate may result in serious (possibly fatal) heart and blood pressure problems.

Methylphenidate should be given cautiously to emotionally unstable patients, especially if there is a history of alcohol or drug abuse. These patients may be more likely to unnecessarily increase their doses or take this medication too often. Long-term overuse of this medication may lead to reduced drug effect, drug dependence, and abnormal behavior.

Take this medication only by mouth. Serious mental/mood changes (e.g., psychosis) may occur, especially if this drug is abused.

If methylphenidate must be stopped, it should be stopped gradually over time. Follow your doctor's instructions on how to gradually lower the dose. In some patients, long-term monitoring may be required after the medication is stopped.
