Melatonin is generally safe for short-term use, but further research is required to assess the long-term safety of melatonin use. In the United States, melatonin is considered a dietary supplement, which are regulated less strictly by the Food and Drug Administration than prescriptions and over-the-counter medications. Federal law doesn’t require dietary supplements to be proven safe to FDA’s standards before they are sold.

Furthermore, some melatonin supplements may not contain what is listed on the product label. Researchers tested 31 commercial supplements and found that most products contained far more or far less melatonin than what was listed on the label. Some supplements contained serotonin, a hormone that wasn’t recognized on the product label.

Although melatonin is generally regarded as well-tolerated, it may not be ideal for long-term use, unless specifically instructed by your doctor. Supplemental melatonin shifts the phase of the human circadian clock, and thus warrants caution. The principle of treatment of sleep disorders is first to find the cause of the sleep disturbance, and then treat the conditions causing the distress.

Treatment options for primary sleep disorders, or sleep disorders that aren’t caused by another medical or psychological condition, often include behavioral therapies. Sleep hygiene, sleep restriction, stimulus control, relaxation training, and cognitive therapy are examples of such therapies.

For children, the AAP says the dose should remain low , capping out at no more than 3 to 6 milligrams of melatonin.

    The maximum dosage for adults ranges from 5 to 10 milligrams. If that sounds like a wide spectrum of normal, its because the right dose of melatonin is very individualized. According to University of Missouri Health Care neurologist Pradeep Bollu, MD, while some people respond well to 3 milligrams daily, others may need more or less. If you feel like you need more than 5 milligrams, you should talk to your doctor first before trying a higher dose. The more melatonin you take the more likely you are to have side effects.

It can even do the exact opposite of its intention.

    Other adverse side effects may include:

    • nightmares/vivid dreams
    • headaches
    • irritability or mild anxiety

    The use of melatonin supplements can affect blood pressure in certain people. This result could be good or bad, depending on whether a person has low or high blood pressure. One study concluded that melatonin could help prevent hypertension and lower blood pressure in people with type 1 diabetes.

    Though one of the side effects above is an increase in vivid dreams or nightmares, experts believe that this is simply a result of experiencing deeper REM sleep. Interestingly enough, one study found that melatonin could improve REM sleep so much that it could be used to help treat REM sleep behavior disorder , which occurs when sleeping people engage in violent or potentially injurious behaviors while acting out dreams during REM sleep.
