When selegiline is taken at doses of 10 mg or less per day for the treatment of Parkinson's disease, there are no restrictions on food or beverages you eat or drink. However, the chance exists that dangerous reactions, such as sudden high blood pressure, may occur if doses higher than those used for Parkinson's disease are taken with certain foods, beverages, or other medicines. These foods, beverages, and medicines include:
...
# Alcoholic beverages or alcohol-free or reduced-alcohol beer and wine.
# Large amounts of caffeine-containing food or beverages such as coffee, tea, cola, or chocolate.
...
Also, for at least 2 weeks after you stop taking this medicine, these foods, beverages, and other medicines may continue to react with selegiline if it was taken in doses higher than those usually used for Parkinson's disease.

Alcohol
The pharmacokinetics and pharmacodynamics of alcohol (0.75 mg/kg) alone or in combination with EMSAM 6 mg/24 hours for 7 days of treatment was examined in 16 healthy volunteers. No clinically significant differences were observed in the pharmacokinetics or pharmacodynamics of alcohol or the pharmacokinetics of selegiline during co-administration. Although EMSAM has not been shown to increase the impairment of mental and motor skills caused by alcohol (0.75 mg/kg) and failed to alter the pharmacokinetic properties of alcohol, patients should be advised that the use of alcohol is not recommended while taking EMSAM.
