Any additional substance that either inhibits or induces activation of the aforestated enzymes can alter metabolism, potency, and duration of effect resulting from ZzzQuil and alcohol.

Is it Safe to Combine ZzzQuil and Alcohol?

The active ingredient in ZzzQuil is diphenhydramine, which is also the active ingredient in the allergy medication Benadryl. And Dr. Fortner warns that while everyone’s metabolism is different, the absolute minimum period of time between a drink and a sleep aid is six hours. Still, he urges people to avoid combining the two altogether—it isn’t worth the risk. What if you simply cannot fall asleep without the help of a sleep aid? The only safe solution, unfortunately, is to forgo that glass of wine.

• Diphenhydramine on the other hand is a drug that is being used against a wide variety of disorders , and can cause adverse reactions.
• Additionally, some substances may not interact with the pharmacokinetics of ZzzQuil and alcohol, but might increase hepatic and/or renal burden, whereby hepatotoxicity and/or nephrotoxicity occur.
• Moreover, high tolerance users may be at increased risk of exceeding safe dosing thresholds for ZzzQuil and alcohol, some of which may yield severe adverse reactions and/or prove to be fatal.
• The combination can cause side effects like drowsiness, dizziness, anxiety, or increased blood pressure.
• Reliant on sleep aids—in part because they don’t promote that deep sleep everyone needs.

Read on for more information on the uses, dosage, and safety of taking ZzzQuil. Now, since both alcohol and ZzzQuil cause lethargy and drowsiness, this effect gets pronounced when you combine them. For some, this may seem as a desirable effect, but it’s not.

Variables that influence severity of effects from mixing ZzzQuil and Alcohol

Specifically, the lower a person’s tolerance relative to the dosage of ZzzQuil and alcohol administered, the more substantial the physiologic reaction will be, thereby increasing likelihood of serious adverse reactions. On the other hand, the greater a person’s tolerance relative to the dosage of ZzzQuil and alcohol administered, the less substantial the physiologic reaction will be, thereby minimizing likelihood of deleterious effects. Melatonin is a dietary supplement that many people view as a safer sleep aid than prescription pills. It’s a hormone that your body naturally produces to keep your sleep cycle, or circadian rhythm, consistent. Even though it’s available over-the-counter, it should not be mixed with alcohol. The combination can cause side effects like drowsiness, dizziness, anxiety, or increased blood pressure.

Not only that, the combination is likely to make any sleep you do get relatively useless.

It should be noted that some individuals may have a high tolerance to alcohol but not diphenhydramine – or vice-versa. Common sense would suggest that, the larger the dose of the substance ingested to which you have low tolerance, the more significant the effect of that particular substance on your physiology from the combination. The extent to which you’ve developed physiologic tolerance to diphenhydramine and/or alcohol will also influence how you respond to the co-ingestion of ZzzQuil and alcohol.

Is it safe to drink alcohol while taking prescription sleep aids?

Mixing sleeping pills with alcohol can diminish your breathing to a dangerously low level—a potentially life-threatening scenario. If you’ve taken a glass of wine at dinner, and then you’re taking ZzzQuil around 11 at night, then there’s no problem. Your body will have already handled the alcohol, and there will be no interactions anymore. However, what is dangerous is if you’re having several drinks, or if you’re binge drinking, and then taking ZzzQuil to fall asleep. Other substances may alter metabolism in ways that inhibit the physiologic effect of ZzzQuil and alcohol, thereby decreasing odds of adverse pharmacokinetic-related reactions. Additionally, some substances may not interact with the pharmacokinetics of ZzzQuil and alcohol, but might increase hepatic and/or renal burden, whereby hepatotoxicity and/or nephrotoxicity occur.

Diphenhydramine binds to the histamine-1 receptor in the body. This receptor is present in many areas of the body, including the respiratory tract, abdominal tract, immune cells, and brain. Antihistamines reduce the effect of histamines, which are natural chemicals that the body produces during an allergic reaction. Alcohol will help you fall asleep in the beginning, but later on during the night, you will wake up often.

What if you have a glass of wine, and inadvertently take a sleep aid later?

It is also important to avoid drinking alcohol when taking ZzzQuil as this can increase drowsiness. One study found that long term dosage of benadryl can cause dementia. The link between this is that anticholinergic drugs block community fairbanks recovery center the effect of acetylcholine, which is involved in learning and memory. Alcohol is also linked with this, and such a combination will make things worse. So when you combine both, you also double the dehydration effects.

Older adults should use ZzzQuil with caution as side effects such as drowsiness, dizziness, and low blood pressure can increase the risk of falling. Diphenhydramine is an antihistamine that people commonly use to treat allergic reactions, itchiness, and hives. The most common side effect of diphenhydramine is drowsiness.

If you think you may have a medical emergency, immediately call your physician or dial 911.
