Taking 10 mg of melatonin is sometimes considered a higher dose, but it may be used in certain cases under medical guidance. Short-term studies suggest that 10 mg can be tolerated without serious harm in healthy adults, although it is not usually the first recommended dose.
Most people respond to lower doses, and higher amounts like 10 mg are more likely to cause mild side effects such as drowsiness, headache, or dizziness. Research also shows that while serious side effects are uncommon, the risk of minor symptoms increases as the dose goes up.
In clinical practice, melatonin is often started at much lower doses and increased only if needed. Some guidelines indicate that 10 mg may be used as an upper limit in specific situations, but typically under supervision rather than for routine use.

It is best not to self-adjust to higher doses without advice. A primary care provider or sleep specialist can help determine the safest and most effective dose based on your needs.
