Who qualifies for Melatonin

Melatonin is a hormone that regulates your sleep-wake cycle. Doctors look for specific criteria when considering a Melatonin prescription. Generally, it's prescribed for sleep disorders like insomnia, jet lag, or delayed sleep phase syndrome. The doctor will assess your medical history, current medications, and the nature of your sleep issues to determine if Melatonin is safe and effective for you. Certain conditions or medications might make Melatonin unsuitable, and the doctor will carefully evaluate these during your online consultation.

What Melatonin actually does (and doesn't do)

Melatonin works by signaling to your body that it's time to sleep. It helps to adjust your internal clock, making it easier to fall asleep and improving overall sleep quality, especially if your natural Melatonin production is disrupted (e.g., due to jet lag or shift work). It is not a sedative or a sleeping pill in the traditional sense, but rather a sleep regulator. Realistic timelines for seeing benefits can vary, but many users report improvements within a few days to a couple of weeks of consistent use. Melatonin does not guarantee instant sleep or cure underlying medical conditions causing sleep disturbances; it supports your body's natural sleep processes.

Side effects and when to stop

While generally well-tolerated, Melatonin can cause side effects. Common ones include daytime drowsiness, dizziness, headache, and nausea. Less common but more serious side effects can include temporary feelings of depression, mild tremors, anxiety, or abdominal cramps. It's crucial to inform your doctor of any existing medical conditions or medications you are taking, as Melatonin can interact with certain drugs (e.g., blood thinners, immunosuppressants). If you experience severe or persistent side effects, or if your sleep problems worsen, you should stop taking Melatonin and consult your doctor immediately.
