From the manufacturer

It is typically safe for adults to take melatonin every night for short periods of time.

“If melatonin for sleep isn't helping after a week or two, stop using it,” says Buenaver. “And if your sleep problems continue, talk with your health care provider. If melatonin does seem to help, it's safe for most people to take nightly for one to two months. “After that, stop and see how your sleep is,” he suggests.

Diphenhydramine also causes drowsiness, and can be used by adults and children 12 years of age and older who occasionally have trouble sleeping (insomnia). The effects of diphenhydramine can last for up to 6 hours. If you have trouble sleeping, do not take this medication for more than a few nights in a row.

In some parts of the world, including the USA and Australia, melatonin is considered a supplement rather than a drug and it can therefore be sold in health food stores and online without a prescription or doctors' consultation.

Melatonin is generally safe for short-term use. Unlike with many sleep medications, with melatonin you are unlikely to become dependent on it, have less response to it after repeated use or experience a hangover effect. The most common melatonin side effects include: Headache.
