The Potential Side Effects of Melatonin
Melatonin is a hormone that is produced naturally by the pineal gland in the brain. One of the major functions of melatonin is to readjust the body’s biological clock; therefore it is a popular remedy for insomnia and jet lag. There are some studies that have shown melatonin to be beneficial to the immune system and in the prevention of cancer; melatonin is also reported to slow the aging process. As with any hormonal supplement, there are potential melatonin side effects that you need to be aware of before taking the supplement.

Rarely, allergic reactions to melatonin have been reported. If you experience symptoms of a severe allergic reaction stop taking melatonin and seek emergency medical attention immediately. These symptoms include difficulty breathing, closing of the throat, swelling of the lips, tongue or face and hives.
Other less serious side effects that have been reported with melatonin include very vivid dreams or nightmares. Taking too much melatonin can disrupt your body’s circadian rhythms (your body’s natural clock). Melatonin can cause drowsiness if taken during the day; and if you are drowsy the morning after taking melatonin, try taking a lower dose. Additional side effects include stomach cramps, dizziness, headache, irritability, decreased libido, breast enlargement in men and decreased sperm count.
Women who are pregnant or nursing should not take melatonin because it could interfere with fertility. There have been studies that have shown melatonin to worsen the symptoms of depression; therefore people with depression should consult their physician before taking melatonin supplements. In the past, it was thought that melatonin levels decrease with age; however, newer evidence has brought this theory into question. Consequently, people over 65 should ask their doctor before taking melatonin supplements, so blood levels of the hormone can be monitored.
Melatonin may have the potential to interact with several different types of common medications; therefore if you are taking any prescription medications it is wise to consult your physician before beginning a melatonin supplement. Melatonin has been shown in animal studies to reduce the effect of certain antidepressants; however more research is needed to determine if it has the same effect in humans. Melatonin may cause certain blood pressure medications to be less effective and may increase the risk of bleeding in those taking anticoagulants (blood thinners). Melatonin should not be taken by people taking steroids and immunosuppressant medications; it can cause these medications of lose their effectiveness.
Melatonin should be used cautiously, especially by anyone taking any of the medications listed above; however the use of melatonin for short-term insomnia or jet lag is safe. Always begin with a low dose and take only the lowest dose that achieves your desired result; discontinue and seek medical attention immediately if a severe allergic reaction occurs. As with any hormonal supplement, it is best to consult with your health care professional before using the supplement.
