Some antibiotics have very serious interactions with alcohol, and some have no known interaction at all. Always check with your doctor before drinking if you’re on antibiotics.
Even if you’re taking an antibiotic that isn’t believed to interact with alcohol, here are several reasons you may want to avoid alcohol anyway:
alcohol can worsen antibiotic side effects
alcohol can decrease antibiotic effectiveness
drinking can slow down the body’s healing process
alcohol can interfere with how your body breaks down antibiotics
