The pill imprinted “G651”
The imprint G651 appears on 8 different products in the FDA data: Acetaminophen Diphenhydramine HCL 500 mg / 25 mg, Acetaminophen Diphenhydramine HCl 25 mg / 500 mg, Acetaminophen Diphenhydramine HCl 500 mg / 25 mg, Acetaminophen and Diphenhydramine HCL 500 mg / 25 mg, and more. 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.

This is what the label lists, and nothing more. An ingredient not appearing here does not mean the product is free of it — formulations differ between manufacturers and between generic versions of the same pill, and “gluten-free” or “dye-free” is a claim only the manufacturer can make. If you have coeliac disease or a diagnosed allergy, confirm with the pharmacist against the pack in front of you.
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.
