Are melatonin and over-the-counter sleep aids good choices for insomnia?
Short answer
Melatonin and over-the-counter sleep aids are not the first-line treatment for chronic insomnia. Melatonin may be useful for certain sleep-timing problems, but its benefit for chronic insomnia is uncertain. Results vary. Ask a physician before using sleep products, especially if you take other medicines or have health conditions.
Melatonin helps signal when it is time to sleep. It may be used for certain problems with sleep timing, but that is different from treating chronic insomnia. Evidence for its use in chronic insomnia is limited. Results vary. In the United States, melatonin is sold as a supplement, and the amount and quality can differ between products.
Many over-the-counter sleep aids contain sedating antihistamines, such as diphenhydramine or doxylamine. These can cause next-day drowsiness, dry mouth, constipation, confusion, or trouble urinating. Older adults may be especially sensitive to these effects. These products are not a good long-term plan for chronic insomnia.
Check labels carefully. Nighttime cold or pain products may contain several ingredients, including medicines you do not need. Combining products can lead to taking the same ingredient twice. Avoid mixing sleep aids with alcohol or prescribed sleep medicines unless your physician says it is safe.
Tell your physician about every supplement and nonprescription product you use. For ongoing insomnia, ask about CBT-I and whether another health condition needs attention before adding a sleep aid.
