Sleep is an essential part of our lives, and when we struggle to get a good night's rest, many of us turn to over-the-counter (OTC) sleep aids. These medications are easily accessible without a prescription and come in various forms, from pills to teas. But do they really work? OTC sleep aids can contain a variety of ingredients, including antihistamines, melatonin, valerian root, and CBD. While these medications can help you fall asleep, their overall benefits are questionable, and side effects such as daytime grogginess, blurred vision, and constipation may occur. Furthermore, the long-term effectiveness and safety of these aids are uncertain, and they may not address the underlying causes of your sleep issues. So, while OTC sleep aids might provide a quick fix, they may not offer a long-term solution for your sleep troubles.

What You'll Learn
Valerian root and herbal supplements
Valerian root is a popular herbal sleep aid that has been used since ancient times. It is available in various forms, including tea, capsules, tinctures, and tablets, and can be purchased without a prescription in pharmacies, grocery stores, and online. Valerian root is believed to act on certain receptors in the brain, slowing down the nervous system and promoting relaxation and sleep. While it is generally considered safe, it is always advisable to consult a healthcare professional before taking any herbal supplements.
The use of valerian root for medicinal purposes dates back to ancient Greece and Rome, where it was used to treat various ailments such as migraines, tiredness, stomach cramps, and insomnia. Today, valerian root is primarily used to address insomnia, anxiety, premenstrual syndrome (PMS), menopause symptoms, depression, and headaches. It is particularly popular in European countries such as France, Germany, and Sweden.
Valerian root contains valerenic acid, which is known to affect GABA receptors in the brain. These receptors are involved in reducing anxiety and promoting relaxation. Additionally, valerian root is believed to impact serotonin receptors, which play a role in regulating mood and sleep. Research suggests that valerian root may reduce the time it takes to fall asleep and improve overall sleep quality and quantity. However, it is important to note that human studies on the effects of valerian supplements on anxiety, stress, and mental health are limited, and more research is needed.
When considering valerian root as a sleep aid, it is essential to consult a healthcare professional to determine if it is suitable for your specific needs. While valerian is generally well-tolerated, some people have reported minor side effects, and it may not be safe or appropriate for everyone. The recommended dosage of valerian root for supporting sleep quality is 450–1,410 mg of whole valerian root per day for 4–8 weeks.

CBD/cannabidiol
CBD, or cannabidiol, is a non-psychoactive compound derived from the cannabis plant. It is commonly used to reduce pain, anxiety, and inflammation, and it may also improve sleep. CBD is available in multiple forms, including pills, edibles (such as gummies), patches, creams, oils, and tinctures.
While CBD is widely considered safe for most people, it is not approved by the Food and Drug Administration (FDA), and there is limited clinical research on its effectiveness as a sleep aid. A 2022 research review concluded that CBD has a minimal effect on sleep disorders and can even negatively affect some people. However, many people who take CBD for insomnia or other sleep issues report improved sleep. One study found that 65% of participants experienced improved sleep after using CBD to treat their anxiety. Another study suggested that CBD may benefit people with certain sleep disorders, including insomnia.
It is important to note that the effects of CBD can vary among individuals, and it may not work for everyone. Additionally, the quality of CBD products can vary, and they may be inaccurately labelled. As with any sleep aid, it is recommended to consult a doctor or medical professional before use, especially if you have a medical condition or are taking other medications.

Antihistamine medications
Antihistamines are a common ingredient in over-the-counter (OTC) sleep medications. They work by blocking histamines, which are substances in the body that cause alertness. While antihistamines can be effective short-term sleep aids, they are not intended for long-term use. This is because the body can quickly build up a tolerance to them, reducing their effectiveness over time. Additionally, they may cause side effects such as daytime grogginess, blurred vision, confusion, and constipation, which can be particularly problematic for older adults.
The two most common antihistamines found in OTC sleep aids are diphenhydramine and doxylamine. Diphenhydramine is typically eliminated from the body more quickly than doxylamine, resulting in less lingering grogginess the next day. It is also generally milder and associated with fewer side effects. Diphenhydramine is the active ingredient in Sleep Eze, Sominex, Nytol, Tylenol PM, and Unisom SleepGels. Doxylamine succinate, on the other hand, is one of the most sedating antihistamines available over the counter. It causes rapid and marked drowsiness in most individuals but may also lead to daytime sleepiness and side effects like dry mouth, blurry vision, constipation, and difficulty urinating. Doxylamine is the active ingredient in products like Unisom SleepTabs and Kirkland Signature Sleep Aid.
It is important to note that while OTC antihistamine sleep aids are readily available, they should be used with caution. They can interact with other medications or substances, such as alcohol, and may not be suitable for certain individuals, especially older adults or children. Always follow the instructions and recommended dosages on the packaging, and consult a healthcare professional if you have any concerns or questions about using these products.

Melatonin supplements
Melatonin is a hormone that is produced naturally by the body to regulate the sleep-wake cycle. Melatonin supplements are synthetic versions of this hormone and are available over the counter. They are typically used to help with insomnia and jet lag, or for night owls who need to adjust their sleep schedule. Melatonin supplements have been found to help people fall asleep faster and improve sleep quality, duration, and consistency.
It is recommended that melatonin supplements be taken two hours before bedtime, and at a dosage of 1 to 3 milligrams. It is also advised to keep lighting low during this two-hour period, as blue and green light can reduce the effectiveness of melatonin. Exposure to daylight during the morning and afternoon can also help to regulate the body's production of melatonin.
While melatonin is considered safe for most people in the short term, it is not recommended for those who are pregnant or breastfeeding, or those with certain medical conditions such as autoimmune disorders, seizure disorders, or depression. Melatonin supplements may also interact with other medications, so it is important to consult a healthcare professional before taking them. The most common side effects of melatonin supplements include drowsiness, headaches, and vivid dreams or nightmares.
It is important to note that melatonin supplements are not regulated by the Food and Drug Administration (FDA) in the same way that other medications are. This means that the safety and accuracy of the listed dosage on the label may be uncertain. Therefore, it is generally recommended to practice good sleep hygiene and develop a consistent sleep schedule before resorting to melatonin supplements.

Prescription sleep aids
While over-the-counter sleep aids are easily accessible, it is recommended that you consult a healthcare provider before taking them. Prescription sleep aids are stronger than over-the-counter sleep aids and are often recommended for short-term relief. They work in different ways, depending on the type of medication. For instance, Benzodiazepines stimulate a chemical in the brain called GABA, which leads to sedation, muscle relaxation, and reduced anxiety. Z-drugs, such as zolpidem (Ambien) and eszopiclone (Lunesta), slow down brain activity.
One example of a prescription sleep aid is Doxepin, sold under the brand name Silenor. Doctors may recommend Silenor for people with insomnia for up to three months. It is available in 3 and 6-milligram doses, and patients should consult a doctor to determine the most suitable dose. Another prescription sleep aid is Rozerem, which has a low likelihood of misuse or dependency. However, it can still cause side effects, including allergic reactions in some individuals.
Suvorexant, sold under the brand name Belsomra, can help individuals fall asleep and maintain sleep. However, it carries a risk of misuse and dependency and may cause CNS impairments that affect activities like driving. Trazodone, also known by the brand name Desyrel, is a medication that modulates serotonin and is typically used to treat major depressive disorder. Lower doses of Desyrel, ranging from 25 to 100 mg, may help individuals fall and stay asleep with fewer side effects. However, it may increase thoughts of suicide, and patients should limit their alcohol consumption while taking this medication.
