Melatonin is a very short-acting substance, remaining in the body only a few hours. It is not regulated in this country, so purity and potency of purchased products may vary. 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. 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. Melatonin should not be taken with steroids (cortisone, prednisone, etc.). hh!`(   ` :!
