Popular checks
Most risk comes from ethanol and amount. A few medicines—including linezolid, MAOIs and warfarin—need extra drink-type context.

A green dot does not mean “cleared to drink”. It only means no specific alcohol interaction is known; illness and medicine side effects still matter.
Common questions
Clear answers to the easy-to-misread parts
Does alcohol interact with every antibiotic?
No. Amoxicillin, azithromycin, many common cephalosporins and ciprofloxacin usually have no specific alcohol reaction, although alcohol may worsen nausea, dizziness or dehydration. Metronidazole, tinidazole and a few special medicines require clear avoidance.
Is beer, wine or spirits safer?
For most interactions, ethanol is the issue, so switching drinks does not make a high-risk combination safe. Linezolid and MAOIs are important exceptions: tyramine in fermented drinks such as tap beer and red wine can cause a dangerous blood-pressure rise.
Can I just wait a few hours after drinking?
Except where a label gives a clear interval, there is no universal hour-count. Amount, drinking speed, food, liver and kidney function, drug half-life and other medicines all matter. This tool does not replace that judgment with a false-precision countdown.
What if I already mixed the medicine and alcohol?
Stop drinking more; do not double doses, make yourself vomit or drive. Call 995 for reduced consciousness, abnormal breathing, seizure, collapse, chest pain, severe confusion, vomiting blood or black stools. If it is not an emergency but a dose is due, contact a pharmacist or prescriber.
