Ampicillin pill images

Ampicillin (Principen) is supplied as capsules by 2 labelers, and each one stamps its own code on the pill. The 4 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

Ampicillin is also supplied as Injection, Powder, For Solution, Powder, For Solution, Injection, Powder, For Suspension. 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.
