The pill imprinted “ML4”
The imprint ML4 appears on 3 different products in the FDA data: Levothyroxine Sodium 25 ug, Tramadol Hydrochloride 50 mg, Levothyroxine Sodium. 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.
