Can You Take Melatonin With Nyquil 


Can You Take Melatonin With Nyquil 

Many Nyquil products can be purchased over-the-counter. However, most of them contain the following active ingredients.

  • Acetaminophen
  • Dextromethorphan
  • Doxylamine

Dextromethorphan and Acetaminophen are used to manage pain. Doxylamine is an antihistamine used for sleep, runny nostrils, itching, itching, and watery eye.

NyQuil’s ingredient that causes sedation is Doxylamine. It is a first-generation antihistamine, similar to Benadryl.

The body naturally produces melatonin to regulate sleep-wake cycles. However, it is often used as an over-the-counter supplement to treat insomnia.

Online interaction checks often list NyQuil products as well as melatonin, as they have an interaction due to their additive results.

Melatonin and doxylamine cause sedation and mild CNS (central nervous systems) depressant effects. These products should be used with caution.


Although there have not been any studies to evaluate the risks of NyQuil and Melatonin being used together, it is clear that both can cause sleep-related disorders, sedation, and respiratory depression.

These two products should be used together. If you notice unusual sleep-related behaviour, one product may need to stop.

You may need to use both melatonin and Nyquil in certain situations, such as if you’re using it to treat jet lag (i.e. You may need to combine both melatonin and melatonin in certain situations, such as when you are trying to restore your normal sleep-wake cycle.

How Antihistamines Work

Antihistamines can bind to histamine receptors in the skin, nose, eyes and lungs. Antihistamines bind to histamine receptors in the nose, eyes, and skin and alter their shape.

First-generation antihistamines like Doxylamine aren’t selective for any one tissue and therefore are more likely to cause sleepiness. As an over-the-counter sleep aid, diphenhydramine (Benadryl), and Doxylamine (Benadryl), can be used.

The body develops tolerance to antihistamines over time. These should not be used as a long-term sleep aid.


The pineal gland secretes melatonin, a hormone. It regulates other hormones and helps maintain the body’s circadian rhythm. The circadian rhythm, an internal 24-hour clock that controls when we fall asleep and wake up, plays a crucial role in our sleep cycles. Your body produces more melanin when it is dark. The production of melatonin decreases when it is bright. The body’s normal melatonin cycle can be disrupted by exposure to bright light in the evening or too little sunlight during the day. Poor vision, shift work, jet lag and other factors can disrupt the body’s normal melatonin cycle.

Melatonin is also responsible for controlling the release and timing of female reproductive hormones. It determines when a woman begins to menstruate and the frequency and length of her menstrual cycles. It also helps when a woman goes into menopause. Preliminary research shows that women with low melatonin levels are at higher risk for pre-eclampsia, a condition that can lead to premature birth.

Researchers believe that melatonin levels could be linked to ageing. Young children, for example, have the highest levels of nighttime melatonin. These levels decrease as we get older, according to researchers. People believe that older adults may have lower levels of melatonin, which could explain why they are more tired and fall asleep earlier than their younger counterparts. Newer research has questioned this theory.

Strong antioxidant properties are associated with melatonin. It may strengthen the immune system, according to preliminary evidence.

Talk to your doctor before you consider taking melatonin supplementation.



Research suggests that melatonin supplements can help those with disturbed circadian rhythms, such as those with jet lag and those who work night shifts, and those with low levels of melatonin (such as seniors or people with schizophrenia), to sleep better. The scientific literature supports the idea that melatonin supplements can help prevent jetlag in those travelling across 5 or more time zones.

Some clinical studies have shown that when used for short periods (days or weeks), melatonin is more effective than a placebo at reducing sleep time, increasing sleeping hours, and increasing alertness during the day. However, it isn’t clear how melatonin works. According to some studies, it may only decrease the time taken to fall asleep by a few seconds.

Numerous human studies have examined the effects of melatonin supplementation on sleep quality in healthy individuals. There have been many studies that tested the effects of melatonin supplements on sleep. Most often, they were taken 30-60 minutes before bedtime. The results have not been consistent. There is evidence that melatonin works best for those over 55 with insomnia. A study of 334 older people found that people with primary insomnia experienced a faster fall asleep, better sleep, more alertness in the morning and a higher quality of life.

Heart Disease

Numerous studies have shown that melatonin is cardioprotective, with antioxidant and anti-inflammatory properties. Research suggests that melatonin may be able to lower blood pressure and improve cholesterol profiles. Further research is required.


Supplements containing melatonin may help with sleep problems associated with menopause. Studies have shown that it can improve quality of life and protect against bone loss in perimenopausal females. It does not seem to alleviate other symptoms associated with menopause, such as hot flashes. Melatonin supplement use by women in their peri- or postmenopausal years should be limited as long-term effects are unknown.

Withdrawal of Benzodiazepine

Research suggests that melatonin may be beneficial for elderly patients who have insomnia. It is used to help them stop or taper off benzodiazepines like Valium, alprazolam(Xanax) or lorazepam/Ativan. Taking controlled-release melatonin increased sleep quality for those who have stopped using benzodiazepine. Further research is required. If you’re not under the care of a medical professional, it is best never to mix melatonin and sedative medication.
