What's in amoxicillin?

Amoxicillin itself is the active drug. Here’s the basics:

- Active ingredient: amoxicillin (usually as amoxicillin trihydrate; some products use other salt forms).
- Class: a beta-lactam antibiotic in the penicillin family.
- Sometimes given with clavulanic acid (as in Augmentin) to broaden activity; that’s a different product (amoxicillin + clavulanate), not plain amoxicillin.

Inactive ingredients (fillers, binders, disintegrants, colorants, etc.) vary by brand and strength. To know the exact inactive ingredients of a specific product, check the product label or patient information leaflet. If you tell me the exact brand/strength, I can look up its ingredients for you.
