What should you know about melatonin and epilepsy?

Melatonin is a hormone involved in the body clock. A supplement may change sleep timing or cause next-day drowsiness, while irregular sleep and sleep deprivation can affect seizure control for some people. Epilepsy also includes different seizure types and treatment plans, so advice cannot be based on the supplement alone. The clinician may need to review your seizure diary, usual sleep pattern, other medicines, alcohol or caffeine use, and the exact product and dose.

Ask your neurologist or GP before starting, stopping, or changing melatonin. Bring the package or product details and a list of prescribed medicines, non-prescription products, and supplements. Keep epilepsy medicine on its usual schedule unless your prescriber changes it. Support sleep with a consistent bedtime, a dark quiet room, limited late caffeine, and a wind-down routine. Record when melatonin is taken, sleep quality, daytime drowsiness, and any seizure or unusual event. Never use melatonin as a replacement for anti-seizure treatment.

Seek emergency help for a seizure lasting longer than your personal emergency plan allows, repeated seizures without recovery, breathing difficulty, serious injury, or failure to regain normal awareness. Contact your epilepsy team promptly after a new seizure pattern, a cluster of seizures, marked daytime sedation, or a suspected medicine interaction. Do not drive or undertake hazardous tasks if you feel unusually drowsy.

Is melatonin suitable with my seizure type and current medicines? What product and timing should be considered? How should I record sleep or seizure changes? What symptoms mean I should stop and call for advice?
