ZzzQuil and Alcohol: Risks, Interactions, and What You Need to Know

Whether you are taking a prescription medication or an over-the-counter (OTC) drug, it is always a dangerous idea to drink alcohol at the same time. ZzzQuil is made out of diphenhydramine, which is also found in Benadryl and other allergy medications. When used properly, ZzzQuil can help you fall asleep. However, it can cause severe side effects if you take it in conjunction with alcohol or other drugs.

Understanding ZzzQuil: What It Is and How It Works

ZzzQuil is used to help people with occasional sleeplessness fall asleep. It is made out of diphenhydramine hydrochloride, also known as diphenhydramine hcl, an antihistamine. As such, diphenhydramine can lead to drowsiness. Because of its effectiveness in causing sleepiness in allergy sufferers, diphenhydramine also became the active ingredient in some over-the-counter sleep aid products.

While ZzzQuil may be an effective nighttime sleep aid in the short run, it can become less effective over time. Your body can develop a tolerance to the drug. Eventually, this means the standard dosage will stop inducing sleep at the same level. This tolerance can lead to it becoming habit-forming.

When you use ZzzQuil before bed, it helps you fall asleep quickly. It is designed to block histamine receptors in your mind. Besides playing a role in allergies, your histamine receptors control how alert you feel. When these receptors are blocked, you are able to feel drowsy and ready for bed. The drug can impact your central nervous system, which can also promote feelings of drowsiness.

Besides blocking histamine receptors, ZzzQuil is also able to block acetylcholine receptors. These receptors are in charge of your muscle movement, attention, memory ability, and other functions. It is important to remember the dangers of mixing alcohol and zzzquil and to understand the effects of zzzquil before using it.

The Dangers of Mixing ZzzQuil and Alcohol

If you are currently taking ZzzQuil, you should not drink at the same time. When ZzzQuil is combined with alcohol, it has a stronger effect on the central nervous system. As a result, many of ZzQuil’s negative side effects will become amplified. While some of these side effects are minor, potentially serious problems can occur if you mix this over-the-counter drug with alcohol.

Enhanced Sedation and Impaired Coordination

ZzzQuil and alcohol are both known for having a sedative effect. When they are mixed together, this means they will increase the level of drowsiness you experience. If you are trying to drive or manage everyday tasks, it may become impossible to remain awake.

Besides increasing the sedative effects, this drug combination can also impact your motor skills and coordination. As a result, you are more likely to fall or become injured. If you are at work or trying to drive, this side effect can be especially dangerous.

Respiratory Depression: A Potentially Fatal Risk

When you combine these drugs, it suppresses your central nervous system and respiratory system. Because of this, you may start to breathe in a slower, shallower way. If you consume enough of these drugs, this suppressant effect can become a life-threatening complication.

Cognitive Impairment

Cognitive side effects are common with both drugs. You may develop memory issues and confusion. Often, people suffer from poor judgment when they take this combo, which increases the likelihood of injuries.

Dizziness

When ZzzQuil and alcohol are combined, it can make you feel lightheaded. As a result, you are more likely to fall or become injured.

Overdose Risks

Even if you are careful to take the recommended amounts of ZzzQuil, consuming alcohol at the same time can lead to an overdose. These drugs have a synergistic effect, so it’s easy to take too much unintentionally. If this happens, you can experience a coma. In severe cases, this combination can even be deadly.

Liver and Kidney Strain: The Added Burden

Your liver and kidneys are responsible for processing the drugs and alcohol that enter your body. When you flood your body with more substances, it increases the burden on your kidneys and liver. Older antihistamines appear to be primarily processed by the liver. As a result, these drugs can be especially dangerous for people who suffer from liver damage.

Interactions with Other Medications: Complications and Risks

You should always talk to your doctor before you take any new medications. Diphenhydramine is known for interacting with different cold and allergy medications. It can increase their intended effects and side effects. Additionally, you should be cautious about taking other depressants, like depression and anxiety drugs. Because of its sleep-inducing effects, you should always consult with your doctor before taking narcotic medications, sleeping pills, seizure medications, and muscle relaxers at the same time as ZzzQuil.

Why People Mix ZzzQuil and Alcohol

People may try to combine these two drugs for a variety of reasons. Often, individuals will drink alcohol and take ZzzQuil at the same time in order to fall asleep. Because these products are both sold without a prescription, they may wrongly believe that they are safe.

Whether you combined these drugs for stronger sedation or simply didn’t think about the potential effects, you should never drink while using ZzzQuil. Besides being harmful to your liver and kidneys, this combination can increase the risk of serious side effects. In the short run, these drugs can also lead to dangerous accidents and injuries.

Safer Alternatives for Sleep: Healthy Habits and Professional Help

If you are suffering from severe insomnia, you should never take ZzzQuil and alcohol at the same time. Additionally, ZzzQuil isn’t intended for long-term use. Because of this, your best option is to improve your sleep hygiene and learn effective relaxation techniques.

Sleep Hygiene Practices

Over the long run, good sleep hygiene can help you overcome insomnia. For example, you should start by always going to bed and waking up at the same time each day. This gets your body into a regular pattern, so it starts to feel tired at a set time.

It takes time for your body to adjust, so never switch your sleep schedule suddenly. Instead, gradually adjust your bedtime by 30 minutes a day. Because the body produces melatonin in response to darkness, the best time to sleep is at night. However, this isn’t always possible for night workers.

No matter what time of day you need to sleep, you should always follow the same routine. For example, many people brush their teeth and put on pajamas right before bed. By using the same routine, you can reinforce the idea that it is time for bed so that your mind starts to prepare. To assist in this process, you should schedule 30 minutes of relaxing time to help your body and mind get ready for bed.

During this relaxing time, you should unplug from your electronics and dim your lights. This reduces distractions that could keep you awake. The lower light helps your body produce melatonin so that you feel tired. Because cell phones, laptops, and other sources of blue light reduce melatonin production, they should be avoided completely.

Each person is different, so you may need to practice different relaxation techniques and sleep routines. Depending on your unique needs, you may want to try mindfulness, paced breathing, yoga, meditation, or other relaxation methods.

Melatonin

If you regularly have sleep-related issues, taking melatonin may be able to help. This drug is naturally produced by the body to encourage sleepiness, so it may be able to help insomnia sufferers fall asleep faster. However, you should always talk to a doctor before adopting any new medication or supplement.

Herbal Teas

Some people find that drinking herbal teas helps them to fall asleep at night. Chamomile tea is particularly popular, and some studies show it can improve sleep quality. Additionally, the process of preparing and drinking a warm cup of decaffeinated tea can be a comforting part of your sleep hygiene.

Recognizing the Signs of Trouble: When to Seek Medical Attention

If you have taken ZzzQuil while drinking, you should be attentive to signs of an overdose. The following severe side effects are indications that you need to reach out for professional medical help.

• Shallow breathing
• Lack of responsiveness
• Loss of consciousness
• Extreme thirst and discomfort from severe dehydration

ZzzQuil and Alcohol: A Recipe for Disaster
