Alcohol can affect taking antibiotics, potentially diminishing their effectiveness or causing unpleasant side effects.

It's generally advisable to avoid alcohol during and for 48 hours after completing a course of these antibiotics. Even with antibiotics not known for specific interactions, moderating alcohol intake is wise to allow your body to focus on fighting the infection.
