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.
