What foods or drinks should I avoid while taking Adipex-P?

It is best to avoid beer, wine or other alcoholic drinks while you are taking Adipex-P, the brand name for the stimulant phentermine. Alcohol can aggravate some of the drug's side effects. Adipex-P can also make you drowsy, and impair thinking and reflexes, so you should be careful about driving until you determine how Adipex-P affects you.
