Does melatonin have side effects on insomnia?

If you use melatonin as prescribed, there are generally no side effects. If you use too much melatonin, it will inhibit gonadotropin secretion, leading to endocrine disorders, induced fatigue, no mental, dyspeptic and other abnormal performance. Suggestion: You need to go to the hospital regularly for reexamination to determine the treatment of insomnia.
