FINDING NOTHING HERE DOES NOT MEAN THE COMBINATION IS SAFE. This checks a curated list of a few dozen well-known interactions, not the thousands that exist. Only your pharmacist or doctor, who can see everything you take, can tell you whether a combination is safe. Never rely on a result from this page — or any page — to start or continue two medicines together.
Numbers are listed for 55 countries and can change — if your country is not here, or you are not sure, 112 reaches emergency services across the European Union and works from a mobile in much of the world. Do not drive yourself.

This is general health information for education, not medical advice, and not a diagnosis. It cannot see you, your history, your allergies or your medicines. Never use it to start, stop or change a treatment, and never let it delay you seeking care. If you are worried about symptoms, speak to a qualified doctor; if they are severe or sudden, seek emergency help.
Where this comes from: A hand-curated list of well-established interactions, chosen for how often they appear in ordinary prescriptions and how much harm they cause when missed. It is not a comprehensive interaction database and does not claim to be.
Where this is written from: This site is written from Indian clinical practice. Drug availability and brand names, vaccination schedules, national health programmes and some reference cut-offs differ between countries — a schedule or a threshold that is standard here may not be standard where you are. If you are reading outside India, check anything on this page against your own country’s guidance before you act on it.
