ZzzQuil

ZzzQuil is a sleep aid designed to help relieve occasional sleeplessness and reduce the amount of time it takes to fall asleep. ZzzQuil is available over the counter and is not habit-forming.

The active ingredient in most ZzzQuil products, including ZzzQuil Nighttime Sleep Aid LiquiCaps and ZzzQuil Warming Berry Nighttime Sleep Aid Liquid, is diphenhydramine. Some ZzzQuil products, such as ZzzQuil Pure Zzzs Gummies, contain melatonin instead of diphenhydramine as the active ingredient.

ZzzQuil works because it contains the active ingredient diphenhydramine. Diphenhydramine is an antihistamine that causes drowsiness. This effect can help you fall asleep faster. ZzzQuil also offers some diphenhydramine-free products that contain melatonin, which may help you fall asleep and may help regulate your sleep schedule.

In general, ZzzQuil starts working soon after it is ingested. However, everyone’s biochemistry is different, so the time it takes for ZzzQuil to kick in may vary from person to person. Many different factors may influence how long a dose of ZzzQuil can last. It is best to take ZzzQuil when you have enough time to get a full 8 hours of sleep.

ZzzQuil should only be taken on an as needed basis once per day, just before bedtime. For specific ZzzQuil dosage information, refer to the instructions printed on the product packaging. If you have questions on concerns about how much ZzzQuil to take, you should consult your doctor or pharmacist.

ZzzQuil contains the active ingredient diphenhydramine, which is not habit-forming. Some ZzzQuil products may contain melatonin as the active ingredient instead of diphenhydramine. Melatonin is also not habit-forming.

The side effects of ZzzQuil products formulated with diphenhydramine are usually mild, and may include dizziness, headache, muscle weakness, and dry eyes. Because it is taken by mouth, ZzzQuil may also cause some digestive side effects, such as loss of appetite, nausea, vomiting, or constipation. Taking ZzzQuil with a small amount of food or milk may help reduce upset stomach. If your ZzzQuil side effects are bothersome, you should contact your doctor. If you take too much of this medication, the side effects may be severe or life threatening. If you believe you have taken too much ZzzQuil, you should seek medical attention immediately.

Some ZzzQuil products contain alcohol, including ZzzQuil Warming Berry Nighttime Sleep Aid Liquid. For those who need to avoid alcohol, ZzzQuil offers several alcohol free products, including ZzzQuil Nighttime Sleep Aid LiquiCaps. Be sure to read the ingredients label carefully before making a purchase to ensure that you are selecting the correct ZzzQuil product for your needs.

If you are pregnant or breastfeeding, you should not take ZzzQuil without first talking to your doctor.

If you are taking other medications, you should talk to your doctor or pharmacist before taking ZzzQuil.

The main difference between NyQuil and ZzzQuil is how they are formulated and what they are used for. NyQuil is designed to help reduce nighttime cough, cold, and flu symptoms. NyQuil is formulated with the pain reliever/fever reducer acetaminophen, as well as the cough suppressant dextromethorphan, and the antihistamine doxylamine succinate. In contrast, ZzzQuil is designed to help relieve occasional sleeplessness and only contains one active ingredient, the antihistamine diphenhydramine. (Some ZzzQuil products, including ZzzQuil Pure Zzzs Gummies, are formulated with melatonin instead of diphenhydramine as the active ingredient.)
