Sleep supplements, such as melatonin and valerian, are popular over-the-counter remedies for insomnia and other sleep issues. While these supplements can be effective in aiding sleep, taking too many can lead to adverse side effects and, in rare cases, overdose. Side effects of sleep supplements include drowsiness, headaches, nightmares, and digestive issues. More severe side effects include allergic reactions, dependence on the medication, and parasomnia, a disruptive sleep disorder that can cause dangerous behaviours while asleep. It is important to use sleep supplements with caution and only as directed by a healthcare provider to avoid potential health risks.

Melatonin overdose is rare, but possible and may cause adverse side effects
Melatonin is a hormone produced by the body that helps regulate sleep. It is also available as an over-the-counter dietary supplement for adults and children in the form of pills, creams, gargles, or gels. While melatonin is generally safe for short-term use, an overdose is possible and may cause adverse side effects.
The most common side effects of a melatonin overdose include drowsiness, dizziness, fatigue, headache, confusion, nightmares, hypotension, tachycardia, and hypothermia. In rare cases, an allergic reaction to melatonin can occur, with symptoms such as a skin rash, itching, redness, swelling, blistering, or peeling skin. Anaphylaxis, a life-threatening allergic reaction, has also been reported in some cases.
It is important to note that the effects of melatonin overdose can vary depending on individual factors, such as age, medical conditions, and interactions with other medications. Older individuals, for example, may be more sensitive to melatonin due to their naturally low levels of the hormone. Additionally, melatonin can interact with certain medications, affecting the cardiovascular, dermatological, and central nervous systems.
If you suspect a melatonin overdose, it is crucial to seek medical attention immediately. Call your doctor, 911, or poison control for guidance and treatment options. It is also recommended to wipe the mouth with a soft, wet cloth if a child has taken too much melatonin. However, do not induce vomiting.
While fatal melatonin overdoses are rare, the lack of regulation and clear dosing guidelines has led to concerns about rising melatonin abuse. To ensure safe use, it is always advisable to consult a healthcare professional before taking melatonin supplements, especially when considering long-term use or when taking other medications.

Melatonin interacts with some medications, including hypertension drugs
Melatonin is a natural hormone that helps regulate the sleep-wake cycle. It is produced by a gland in the brain and helps people fall asleep. Melatonin supplements are the fourth most popular natural product taken by adults and the second most popular natural product given to children by parents.
While melatonin is generally safe and well-tolerated at low doses and for short periods, it can interact with certain medications, including hypertension drugs. Melatonin can increase the risk of bleeding when taken with blood thinners like warfarin. It may also enhance the sedative effects of other medications, leading to increased drowsiness and impaired thinking and judgment, especially in the elderly.
Additionally, melatonin interacts with hypertension treatments, and this combination can lower blood pressure to dangerously low levels. This is because melatonin supplements can further decrease blood pressure, which can be dangerous for those already taking medication to manage hypertension. It is important to note that some interactions may not be immediately apparent, especially during sleep, as people may sleep through low blood pressure difficulties.
Calcium channel blockers, a class of drugs commonly prescribed for hypertension, interact with melatonin. These drugs include Adalat, Cardiazem, Isoptin, and Plendil. They work by preventing calcium from entering the cells of the heart and arteries, which reduces the force of the heart's contractions and lowers blood pressure. When combined with melatonin, there is a risk of excessive blood pressure reduction.
It is crucial to consult a healthcare provider before taking melatonin, especially when on any medication, to ensure safe and effective use.

Over-the-counter sleep aids often contain antihistamines, which cause drowsiness
Over-the-counter sleep aids often contain antihistamines, which are drugs that treat allergies but can also cause drowsiness. While this drowsiness may be a welcome side effect for those suffering from allergies, it is generally not recommended to take antihistamines solely as a sleep aid. This is because antihistamines can have other side effects, including altered mental state, urinary retention, and dry mouth, as well as dizziness, and increased risk for dementia and Alzheimer's disease if taken long-term. Additionally, many people develop a tolerance to antihistamines quickly, and they may not be effective for long-term use. Instead, it is recommended to try alternative sleep aids like melatonin, good sleep hygiene, and cognitive behavioral therapy.
Melatonin is a hormone that is produced naturally by the body to regulate the sleep-wake cycle. It is also available as a supplement to help with insomnia or other sleep-related conditions. Melatonin supplements can increase your quality of sleep, how quickly you fall asleep, and how long you sleep. However, it's important to note that melatonin supplements should not take the place of good sleep practices, and most physicians recommend committing to a good sleep routine before turning to supplements.
When taken appropriately for a short amount of time, melatonin is typically safe and well-tolerated. However, it can have side effects such as drowsiness, headaches, vivid dreams, and nightmares. In rare cases, an allergic reaction to melatonin can occur, and in even rarer cases, an overdose of melatonin can be life-threatening. Therefore, it is important to be cautious when taking any sleep supplement, including over-the-counter antihistamines and melatonin, and to consult a healthcare professional if you have any concerns.
It is worth noting that sleep aids, whether over-the-counter or prescription, can have side effects and should not be used long-term without consulting a healthcare provider. When taken night after night, the body may become dependent on sleep aids, and stopping the medication may result in rebound insomnia, where insomnia returns worse than before. Mixing sleep aids with other sedatives or alcohol can also lead to the possibility of overdosing. Therefore, it is crucial to use sleep aids cautiously and under the guidance of a medical professional.

Melatonin supplements should not be used long-term, nor to replace good sleep practices
Melatonin is a hormone produced naturally by a gland in the brain. It helps regulate the body's sleep-wake cycle. Darkness triggers the body to produce more melatonin, signalling the body to sleep. Light decreases melatonin production, signalling the body to be awake. Melatonin supplements are increasing in popularity. They are the fourth most popular natural product taken by adults and the second most popular given to children by parents.
While melatonin supplements can be helpful for some people with insomnia or other sleep-related issues, they should not be used long-term or to replace good sleep practices. Short-term use of melatonin supplements appears to be safe for most people. However, long-term use has not been studied extensively. Melatonin is typically safe and well-tolerated at low doses and for the shortest amount of time possible. Taking too much melatonin can lead to unwanted side effects. While it is rare that an overdose of melatonin could be fatal, it can cause side effects such as drowsiness, headaches, dizziness, nausea, and nightmares. Melatonin may also affect your cardiovascular, dermatological, and central nervous systems. If you are older, you may be more sensitive to melatonin supplements as you have naturally low levels of melatonin.
Additionally, melatonin is not regulated by the FDA, so it is difficult to know if the dose advertised is what you are getting. It is important to talk to a healthcare provider before taking melatonin supplements, especially if you are taking other medications, as melatonin can interact with certain drugs. For example, it may increase the effectiveness of blood-thinning medications like warfarin, increasing the risk of bruising and bleeding. Melatonin might also have effects similar to birth control, making it more difficult to become pregnant.
Overall, while melatonin supplements can be helpful for some people with sleep issues, they should not be used as a long-term solution. It is essential to prioritize good sleep practices, such as maintaining a consistent sleep schedule, limiting screen time before bed, avoiding caffeine and alcohol later in the day, and sleeping in a dark, cool room.

Melatonin may not always contain the amount stated on the label
Melatonin is a natural hormone that helps regulate the body's sleep-wake cycles by interacting with the suprachiasmatic nucleus of the hypothalamus and the retina. It is widely available as a dietary supplement and is the fourth most popular natural sleep product taken by adults. It is also the second most popular natural product given to children by parents.
Because melatonin is classified as a dietary supplement, it is not subject to the same scrutiny as medications approved by the U.S. Food and Drug Administration (FDA). This means that melatonin products may include things that are not safe because they are not well regulated. For example, melatonin products have been found to contain CBD or other supplements.
A study examining 31 melatonin supplements discovered that the actual melatonin content varied widely, ranging from 83% less to 478% more than the labelled content. The study also found that lot-to-lot variability within a particular product varied by as much as 465%. This may mean that consumers have taken more or less of the amount they believe they took.
Experts recommend purchasing melatonin supplements that include the "'USP Verified Mark' on the label to ensure quality and dosing accuracy. The U.S. Pharmacopeia (USP) is an independent nonprofit organization with a voluntary "USP Verified Mark" program for supplements that meet their standards.
