The pill imprinted “C51”
The imprint C51 appears on 4 different products in the FDA data: Dalfampridine 10 mg, Olmesartan Medoxomil, Amlodipine and Hydrochlorothiazide 20 mg / 5 mg / 12.5 mg, Olmesartan medoxomil 5 mg, Tribenzor 20 mg / 5 mg / 12.5 mg. Match the colour and shape below to your pill.
The pictures are diagrams drawn from the shape, colour and imprint on the FDA label — not photographs of the actual tablet. Identify by the imprint, and confirm with a pharmacist.
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.
