How does Diphenhydramine interact with over-the-counter cold and flu medications, and what precautions should be taken to avoid adverse reactions or reduced efficacy?
Diphenhydramine, found in many cold and flu medications, can increase drowsiness. Avoid combining with alcohol or other sedatives. Check ingredient labels to prevent doubling up on antihistamines.
