Can alcohol interfere with this antibiotic's effectiveness?

I’d love to give you the most accurate advice, but first could you tell me which antibiotic you’re taking? Some drugs (like metronidazole, tinidazole, and a few others) have strong interactions with alcohol that can reduce effectiveness or cause unpleasant side‑effects. Other antibiotics (such as penicillins or macrolides) are generally less affected, though alcohol can still irritate your stomach or affect how well your body processes the medication. Once I know the name, I can explain the specific risks and what you should watch for.
