What You'll Learn
Effectiveness of OTC sleep aids
The effectiveness of over-the-counter (OTC) sleep aids is a complex topic, with various factors influencing their efficacy and safety. While OTC sleep aids can help induce drowsiness and improve sleep, their benefits are often debated and may come with certain risks and side effects.
One commonly used OTC sleep aid is diphenhydramine, a first-generation antihistamine. While it can help people fall asleep, its overall benefits are questionable. Diphenhydramine has been associated with psychomotor impairments and daytime sleepiness, and its use may result in less restorative sleep. Additionally, older adults, who account for a significant proportion of OTC sleep aid users, may experience adverse effects such as confusion and an increased risk of falls.
Doxylamine, another antihistamine, is also available OTC and can cause drowsiness. However, it has been less studied than diphenhydramine, and organizations like the AASM and AAFP do not recommend it for sleep onset or maintenance in people with insomnia. Doxylamine is intended for short-term use and may cause side effects such as dry mouth, blurry vision, constipation, and urinary problems.
Melatonin is another popular OTC sleep aid. It is a synthetic version of the natural hormone that regulates the sleep-wake cycle. Melatonin can help adjust the timing of sleep, making it useful for jet lag or shift work. While generally safe, some people have reported side effects like headaches and confusion. However, there is limited evidence that melatonin helps with chronic insomnia, and it may only provide a small improvement in sleep quality.
Valerian, an herbal supplement, is also available OTC and is said to act on brain receptors to slow down the nervous system and induce drowsiness. It has few reported side effects, mainly drowsiness and dizziness, but its exact mechanism is unclear. CBD (cannabidiol), derived from the cannabis plant, is another OTC option that may help with sleep by relieving anxiety, a common contributor to insomnia. However, more research is needed to confirm its effectiveness.
While OTC sleep aids can provide temporary relief for occasional sleep issues, they are not recommended for long-term use. Tolerance to these medications can develop quickly, leading to the temptation to increase dosages. Additionally, they may not address the underlying causes of sleep problems, and chronic use might even lead to persistent insomnia. It is always advisable to consult a healthcare professional before taking any OTC sleep aid to ensure safety and explore alternative treatments for ongoing sleep difficulties.

Safety and side effects
While over-the-counter (OTC) sleep aids are generally safe, they do come with some risks and side effects. It is recommended that you consult your healthcare provider before taking any OTC sleep aid to ensure that it is safe for you and will not interact with other medications.
OTC sleep aids often contain antihistamines, which can make you feel drowsy. However, they can also cause side effects such as dry mouth, blurred vision, constipation, and fatigue. These side effects can be more severe in older adults, who may experience confusion and falls. Additionally, antihistamines can increase the effects of alcohol or other sleep medications, so it is important to avoid combining them with other substances. While OTC sleep aids do not typically lead to dependency, your body can develop a tolerance over time, requiring higher doses to achieve the same effect.
Melatonin is another common ingredient in OTC sleep aids. It is a synthetic version of a hormone naturally produced by the body to regulate the sleep-wake cycle. While melatonin can be helpful for "night owls" and people with jet lag, its effectiveness in treating general insomnia is unclear. Side effects may include headache, dizziness, nausea, and drowsiness.
Valerian is an herbal supplement that acts on receptors in the brain to slow down the nervous system and promote sleep. It has been found to have a minor beneficial effect, but there is limited data on its effectiveness. Valerian is generally considered safe, but it may cause side effects such as headache, dizziness, and nausea, and it may interact with alcohol or other drugs.
CBD (cannabidiol) is also found in some OTC sleep aids. Derived from the cannabis plant, CBD does not produce the "high" associated with marijuana. While studies suggest that CBD may help with sleep by relieving anxiety, it is still a relatively new treatment, and more research is needed to establish its effectiveness. Side effects of CBD may include fatigue, diarrhea, and low appetite.
In summary, while OTC sleep aids can be helpful for occasional sleeplessness, they should be used with caution and only as directed. It is important to be aware of potential side effects and interactions, and to consult a healthcare professional if you have any concerns or if your sleep problems persist.

Natural alternatives
Natural sleep aids are over-the-counter supplements intended to help you fall asleep faster or stay asleep throughout the night. They are usually plant-based, a vitamin or mineral already present in our diets, or supplemental amounts of something produced by the body.
Melatonin
Melatonin is a natural hormone produced in the brain. During the day, your eyes perceive the presence of natural light and signal the brain to secrete hormones (like cortisol) that promote feelings of wakefulness and alertness. As daylight fades in the evening, your brain receives signals to release melatonin, which makes you feel sleepy. Certain factors can hinder or decrease melatonin production, such as exposure to light in the evening, which can confuse the brain into thinking you should feel awake. To boost low melatonin levels, some people take melatonin supplements. These supplements are most commonly made from synthetic components. Melatonin can, however, reduce the effectiveness of some medications and produce unwanted side effects when combined with others. This natural sleep aid may not be recommended for people who have received an organ transplant, experience depression, or have a bleeding or seizure disorder.
Magnesium
Magnesium is another natural sleep aid that can help improve sleep quality.
Valerian Root
Valerian is an herb marketed and sold as a dietary supplement under the name "valerian root". It is often found in OTC sleep aids used to treat insomnia and anxiety. The root of this tall, flowering plant is said to help people fall asleep and quell anxiety and stress.
Cannabinoids
Some natural sleep aids contain natural or synthetic cannabinoids—namely, delta-tetra-hydrocannabinol (THC) and cannabidiol (CBD). Some studies suggest that THC and CBD, alone or in combination, help some people fall asleep, stay asleep, and enjoy higher-quality sleep. However, marijuana and products containing THC have the potential to create dependence, and withdrawal from them can aggravate sleep problems.
Lavender
Lavender is another natural alternative that can help improve sleep.
It is important to consult your doctor before starting any new supplement. Natural does not always mean safe for everyone. Many supplements should not be taken by people who have certain allergies or conditions, or those who are taking other medications. It is also important to understand that natural sleep aids are classified as dietary supplements, which means they are not regulated as strictly as medications.

OTC sleep aids for elderly people
Sleep can become more difficult as we age, and many older adults turn to over-the-counter (OTC) sleep aids to help them get a good night's rest. However, it is important to understand the potential risks and side effects of these products, especially for elderly individuals.
OTC sleep aids commonly contain antihistamines such as diphenhydramine and doxylamine, which have sedative effects. While these medications can help people fall asleep, they may also cause side effects such as dizziness, sedation, confusion, dry mouth, constipation, and urinary retention, which can be more pronounced in older adults. Additionally, older adults are more likely to be taking other medications that could interact with OTC sleep aids, and their slower metabolism can prolong the effects of the sleep aid. Therefore, it is recommended that older adults exercise caution and consult their doctor or pharmacist before taking OTC sleep aids, especially if they plan to use them for more than two weeks.
Some studies have found that a relatively large number of older adults may chronically take OTC sleep aids for insomnia treatment or self-care. For example, among older adults with sleep difficulties, 17.5% used an OTC sleep aid, and 2.7% of the total older adult population. Older adults using OTC sleep aids were also more likely to be taking anticholinergic medications, which can have additive CNS-depressant effects if consumed with alcoholic beverages.
If you are an older adult experiencing sleep difficulties, it is important to address the underlying causes of your sleep problems rather than relying solely on OTC sleep aids. Speak with your doctor or pharmacist about your options and follow safe usage guidelines. Additionally, consider non-medical solutions, as most sleep problems can be corrected without medication.
There are also natural sleep aids that can be purchased over the counter, such as melatonin and valerian root. Melatonin is a natural hormone produced by the brain to promote sleepiness, and valerian is an herb sold as a dietary supplement to help with sleep and anxiety. These options are generally considered mild and safe, but it is still important to consult a healthcare professional before use.

Long-term use of OTC sleep aids
Over-the-counter (OTC) sleep aids are generally not recommended for long-term use. While they can be effective in helping people fall asleep, their benefits are debated, and they may not address the underlying causes of sleep problems. Additionally, long-term use of certain OTC sleep aids, such as antihistamines, has been associated with cognitive side effects, especially in older adults.
Antihistamines, such as diphenhydramine, are commonly found in OTC sleep aids. While occasional use is generally safe, long-term use can lead to confusion, falls, and even contribute to the development of dementia or Alzheimer's disease, especially in older individuals. This is because diphenhydramine blocks a brain chemical called acetylcholine, which is important for attention and short-term memory.
Benzodiazepines, including Valium and Xanax, are another class of medications sometimes used as sleep aids. These drugs are also not recommended for long-term use as they can impair memory and require higher doses over time to achieve the same effect. Narcotic analgesics, such as hydrocodone and oxycodone, are another class of medications that are highly addictive and should be avoided for long-term use.
Melatonin is a natural hormone that helps regulate the sleep-wake cycle and is available as a synthetic supplement. According to Dr. Epstein, melatonin can be taken safely for the long term, although there is limited data on the effectiveness of supplements. Valerian root, an herbal supplement, has also been shown to have a minor beneficial effect on sleep, according to Dr. Epstein. However, it is important to note that supplements are not regulated by the FDA, and side effects such as headaches, dizziness, or nausea may occur.
In summary, while OTC sleep aids can be helpful for occasional sleepless nights, they are not intended for long-term use. It is important to consult a physician to address any underlying causes of sleep problems and to ensure that any medications or supplements are safe and appropriate for your individual needs.
