Check interactions between medications and supplements
Enter the names of medications or supplements you want to check. Add at least 2 drugs.
Enter the generic or brand names of any medications, vitamins, or supplements you take. The checker uses the OpenFDA drug label database to identify known interactions.
Common drug interaction types: Some drugs affect how quickly the body processes other drugs (CYP450 interactions). Others compete for the same receptors. Some can cause dangerous additive effects when combined (e.g., blood thinners, CNS depressants).
This database covers FDA-regulated drugs. Herbal supplements and vitamins may not appear in all cases. For a comprehensive review of all your medications, consult your pharmacist — they have access to professional-grade interaction databases.
