Found a blue capsule and not sure what it is? Blue capsules include several commonly prescribed medications — from sleep aids and antibiotics to antidepressants and antifungals. The most reliable identifier is the imprint code printed on the capsule body. Below are the most commonly encountered blue capsule medications.

Look for text printed on both halves of the capsule. Blue capsules often have white or contrasting print. Record the imprint from both halves, then enter the complete code with "blue" and "capsule" in PillID's identifier.
Some blue capsules (temazepam) are Schedule IV controlled substances. Always verify the source of the pill. For emergencies, call 1-800-222-1222.
