Summary
Melatonin is used to treat sleep disorders like insomnia, which is difficulty falling or staying asleep. It's also helpful for jet lag, which is a temporary sleep problem from traveling across time zones, and shift work sleep disorder, which affects people who work non-traditional hours.
Melatonin works by regulating your sleep-wake cycle. It's a hormone produced by the pineal gland in your brain, which signals to your body that it's time to sleep. Think of it like a natural "sleep switch" that helps you fall asleep and stay asleep.
The usual starting dose of melatonin for adults is 1 to 5 mg taken 30 minutes before bedtime. It's typically taken once daily. Your doctor may adjust the dose based on your response and needs. Always follow your doctor's specific dosing instructions.
Common side effects of melatonin include drowsiness, dizziness, and headaches. These effects vary from person to person and are usually mild. If you notice new symptoms after starting melatonin, they might be temporary or unrelated to the medication.
Melatonin can cause drowsiness, so avoid driving or operating machinery after taking it. It may interact with other medications, so inform your doctor about all medicines you take. Pregnant or breastfeeding women should consult their doctor before use.
