Identify Your Red Round Pill
Enter the imprint code from your pill for an exact match — or search by shape and color to browse all options.
Look for an imprint on both sides of the tablet. Red can range from bright cherry red to dark maroon. Many red round OTC pills (ibuprofen, vitamins) have simple numeric imprints. Prescription red round tablets (like warfarin) carry more specific manufacturer codes.
Enter the full imprint with "red" and "round" in PillID's identifier. For any emergency or concern about an unknown pill, call 1-800-222-1222.
