- Most OTC sleep aids are antihistamine-based medications (such as diphenhydramine) that can result in drowsiness that persists long after one wakes up.
- OTC sleeping aids may lose their effectiveness over time.
- If you are considering an OTC medicine, discuss it with your healthcare provider before deployment.
