Studies show that while melatonin is generally safe for short-term use, some people may experience side effects:
- Common side effects: Headache, dizziness, nausea, daytime sleepiness
- Less common effects: Vivid dreams, anxiety, irritability
- Rare side effects: Depression, mild tremor, mild anxiety
Long-term effects are still being studied. Melatonin can interact with various medications, including blood thinners, diabetes medications, and immunosuppressants. It may also temporarily affect reproductive hormones, so pregnant women should consult their healthcare provider before use.
