Melatonin

Melatonin may be used to treat insomnia, delayed sleep phase syndrome, fibromyalgia, or jet lag. Melatonin is a hormone secreted at night by the pineal gland of the brain. Melatonin is a very short-acting substance, remaining in the body only a few hours. Because dietary supplements, herbs, and other "natural" products are not regulated by the FDA, purity and potency of purchased products may vary.

Proper Use of this Medication:

    * Melatonin is not habit-forming and will not cause a "high" feeling.
    * Sustained-release preparations tend to work better for maintaining sleep.
    * Usual dosages are no more than 3 mg at night, taken 1-2 hours before bedtime.

This medication is usually well-tolerated. However, possible side effects may include:

    * Melatonin may inhibit ovulation, causing some women to have difficulty getting pregnant.
    * Melatonin may worsen depression.
    * Headache, "heavy head", and nausea have been reported, though they tend to be brief.
    * Side effects associated with long-term use are unknown.

The following other medications may require dosage adjustment while taking melatonin:

    * Melatonin should not be taken with steroids (cortisone, prednisone, etc.)
