How to Identify This Pill
- Read the imprint code exactly as it appears (letters, numbers, and any dividing line) — it is the single most reliable identifier.
- Note the shape (round, oval, capsule, etc.) and colour, and compare both against the details above.
- Check the size if you have a ruler or pill gauge — imprint plus size narrows down look-alikes.
- Compare the pill photo above side-by-side with the physical pill in good lighting.
