For most common antibiotics, moderate drinking is fine - but metronidazole and tinidazole are hard exceptions: zero alcohol, plus 48 hours after metronidazole and 72 hours after tinidazole.
Those two cause a disulfiram-like reaction with alcohol: flushing, vomiting, stomach pain, and a racing heart. With amoxicillin, azithromycin, doxycycline, and cephalexin, alcohol does not block the drug. Two softer warnings: linezolid reacts with tap beer and red wine, and heavy drinking while infected worsens dehydration and sleep and amplifies antibiotic side effects like nausea and dizziness.

What to do
Common questions
Can you drink alcohol on antibiotics?
For most common antibiotics - penicillins like amoxicillin, azithromycin, doxycycline, cephalexin - moderate alcohol does not stop them working. The hard exceptions are metronidazole and tinidazole: with these, you must avoid alcohol completely, and keep avoiding it for 48 hours after finishing metronidazole and 72 hours after tinidazole, because the combination causes a nasty reaction - flushing, vomiting, stomach pain, pounding heartbeat. A couple of other caveats: linezolid interacts with tap beer and red wine, and heavy drinking while sick is its own problem - it worsens dehydration, disrupts sleep, and amplifies side effects like nausea and dizziness that many antibiotics already cause. So the sensible version is: check whether your specific antibiotic is one of the reactive ones, and even if it is not, keep it light until you are better.
