Identify Your Pink Capsule
Enter the imprint code from your capsule for an exact match — or search by shape and color to browse all options.
Look for text printed on both halves of the capsule. Pink capsules often have white or black print. Record the complete imprint from both halves, then enter it with "pink" and "capsule" in PillID's identifier. Pink capsules are most often antibiotics or OTC antihistamines — but always confirm with the imprint.
A pink capsule with no imprint at all is most likely an OTC supplement or herbal product. For emergencies, call 1-800-222-1222.
