While melatonin is generally considered safe for short-term use, research has identified several possible side effects:
- Common side effects: Headache, dizziness, daytime sleepiness
- Less common effects: Mild anxiety, temporary depression, mild tremor
- Rare side effects: Mild nausea, confusion, vivid dreams
Long-term use should be monitored by a healthcare provider. Studies show that melatonin can interact with certain medications, including blood thinners and diabetes medications. Pregnant women and those with autoimmune conditions should consult their doctor before use.
