In many countries, melatonin is available both by prescription and as an over-the-counter supplement, depending on local regulations. Some health authorities approve prescription melatonin for children with specific conditions such as autism spectrum disorder, while adults may use low-dose, prolonged-release tablets to manage short-term insomnia. However, there has been a sharp rise in people self-medicating with melatonin, including for their children, often purchasing it online or as unregulated supplements. These products may not meet the same quality or safety standards as approved pharmaceutical preparations.

According to Professor Matthew Walker, an international expert on sleep “In healthy adults, melatonin supplementation increases total sleep time by only about 3.9 minutes on average and boosts sleep efficiency by a mere 2.2%”. It may be more worthwhile to consult with your doctor and investigate the causes of your sleep problems.
