Melatonin Side Effects

February 29th, 2012 by Maggie Heart

Melatonin has been used to ease insomnia, combat jet lag, protect cells from free-radical damage, boost the immune system, prevent cancer, and extend life.

The use of melatonin in cultural and traditional settings may differ from concepts accepted by current Western medicine. When considering the use of herbal/health supplements, consultation with a primary health care professional is advisable. Additionally, consultation with a practitioner trained in the uses of herbal/health supplements may be beneficial, and coordination of treatment among all health care providers involved may be advantageous.

Melatonin is naturally produced in the body in response to the perception of light.

Melatonin has not been evaluated by the FDA for safety, effectiveness, or purity. All potential risks and/or advantages of melatonin may not be known. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Melatonin may also have uses other than those listed in this product guide.

Although uncommon, allergic reactions to melatonin have been reported. Stop taking melatonin and seek emergency medical attention if you experience symptoms of a serious allergic reaction including difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives.
