Before you rely on this
A pill’s appearance varies between manufacturers and generic versions, imprints wear off, and two different drugs can share an imprint. Everything here is transcribed straight from the FDA’s DailyMed labels — we do not alter or infer it — but treat any identification as a starting point and confirm with a licensed pharmacist before taking or discarding a medication.
Wrong pill? Search by imprint, colour and shape in the full pill identifier.
Source: the U.S. National Library of Medicine’s DailyMed Structured Product Labeling — the FDA-required drug labels. Imprint, colour, shape, size and score are transcribed, not inferred. This is reference information, not medical advice.
