Indications & Clinical Uses

ZzzQuil Nighttime Sleep-Aid is primarily used for occasional sleeplessness. It is designed to help individuals who have trouble falling or staying asleep. The active ingredient, diphenhydramine hydrochloride, works by blocking histamine receptors in the brain, which can induce drowsiness and facilitate sleep. This makes it a popular choice for those seeking temporary relief from insomnia or other sleep disturbances.

Common effects of ZzzQuil Nighttime Sleep-Aid may include drowsiness, which is the intended effect to aid in falling asleep. Some users might experience dry mouth, blurred vision, or mild dizziness.
