Look up unknown pills by imprint code, color, and shape — then confirm with a pharmacist before taking anything.
Start with the imprint — that is the strongest clue. Color and shape help when several drugs share similar markings. Treat every online match as a lead, not a diagnosis.

Note every letter and number imprinted on the pill, plus its color and shape. Enter those details into a pill identifier for likely matches. For the most accurate identification, bring the pill to a pharmacist — similar imprints can appear on different drugs.
Online tools can suggest likely matches but are not 100% reliable. Look-alike pills and counterfeit tablets exist. Never take an unidentified pill based on an online result alone.
An imprint is the text, numbers, or logo stamped on a prescription or OTC tablet or capsule. U.S. manufacturers use unique imprint combinations so pharmacists and patients can identify the drug and strength.
Most U.S. prescription tablets must have an imprint. A blank pill may be a vitamin, supplement, compounded medication, or something unsafe. Do not take it — ask a pharmacist or poison control.
Color helps narrow results but is not enough. Many drugs share colors. Always combine imprint, color, and shape — then confirm with a pharmacist before taking anything.
Once you know what a pill likely is, screen it against your full medication list — prescriptions, OTC, and supplements.
