Alcohol

· Severity: Major

· Notes for Consumers: Do not drink alcoholic beverages while taking certain extended-release Methylphenidate products such as Ritalin LA and Metadate CD. Also, side effects from all Methylphenidate products may get worse if you drink alcohol. Check with your doctor or pharmacist before drinking alcohol while you are taking Methylphenidate.

· Notes for Professionals: Alcohol consumption should be avoided during treatment with certain extended-release (ER) dosage forms of methylphenidate (e.g., Ritalin LA, Metadate CD). Results from an in vitro study showed that at an alcohol concentration of 40%, there was a 98% release of extended-release methylphenidate (Ritalin LA) from the 40 mg capsule in the first hour after administration. In addition, concurrent use with alcohol may exacerbate the CNS-related adverse effects of methylphenidate.
