I have been on cephalexin many times in my pamphlet it says that it should not be mixed with alcohol as it may cause abdominal or stomach cramps, nausea, vomiting, headache, dizziness or light-headedness, shortness of breath, sweating, or facial flushing.

Happy New year and have a great time!!

yes i used cephalexin for tonsilities and i was strongly encouraged not to use it with alcohol.
