Acetazolamide pill images

Acetazolamide (Diamox) is supplied as tablets and capsules by 21 labelers, and each one stamps its own code on the pill. The 30 versions below come from the product listings inside their FDA labels: color, shape, size in millimeters, scoring, and the imprint.

Every image is a rendering built from that listing, not a photograph, so the imprint and proportions match the label exactly and the surface finish is an approximation. Confirm any pill against the pharmacy label or a pharmacist before relying on it.

Other forms

Acetazolamide is also supplied as Injection, Powder, Lyophilized, For Solution, Injection, Powder, For Solution. Those have no imprint to identify; the product label on the package is the reference.

Identification is not a guarantee. Different drugs can share a color and shape, imprints wear off, and labelers change designs. Treat a match here as a lead, and confirm it with a pharmacist.
