Can you drink beer while taking femara (letrozole)?

Why are you on it? If you are on the medication to assist in getting pregnant, then alcohol is not your friend. If you are talking about one or two beers on an occasion, it shouldn't make any difference. If you are talking a six-pack a day (or any regular use), alcohol impairs ovulation as well as the maturation of follicles. If it is being used in the setting of breast cancer prevention, alcohol is also not good.
