Quick answer
The NHS says if you take melatonin as prescribed you’re unlikely to become addicted. We found no well-described withdrawal syndrome. NIH’s NCCIH says short-term use appears safe for most people, but long-term safety information is lacking, and a 2023 study found 22 of 25 melatonin gummy products were inaccurately labeled. When you stop, your original sleep problem may return.

Symptoms, phase by phase
Evidence note: The NHS says you’re unlikely to become addicted to prescribed melatonin and that your doctor can help you come off it gradually. NCCIH says short-term use appears safe for most people, long-term effects are unclear, and reported short-term side effects are mild (headache, dizziness, nausea, sleepiness). We found no studies describing a withdrawal syndrome.
After stopping: The first nights (not well studied)
- Return of your original sleep problems
What makes withdrawal longer or shorter
- Why you take it. Insomnia or jet lag may return.
- Product strength. Gummies may contain more or less than the label says (NCCIH).
When to see a doctor or get help now
- Insomnia that lasts for weeks.
- Ask before giving melatonin to children long term.
