Who qualifies for Circadin

Circadin is a melatonin-based medication prescribed for short-term treatment of primary insomnia characterized by poor quality of sleep in patients aged 55 years and over. When you consult with a Hi-Doctor EU-licensed physician, they will assess your medical history, current health status, and sleep patterns. The doctor looks for specific criteria to ensure Circadin is safe and appropriate for you, considering potential contraindications and interactions with other medications. This ensures responsible and effective treatment.

What Circadin actually does (and doesn't do)

Circadin is a prolonged-release formulation of melatonin, a hormone naturally produced by your body that helps regulate sleep-wake cycles. It works by supplementing your natural melatonin levels, helping to reset your body's internal clock and improve sleep quality and onset. Unlike traditional sleeping pills, Circadin is not a sedative; it aims to restore natural sleep patterns over time. Realistic timelines mean you might not see immediate drastic changes, but rather a gradual improvement in sleep quality and duration as your body adjusts.

Side effects and when to stop

Like all medications, Circadin can cause side effects, though not everyone experiences them. Common side effects may include headache, nasopharyngitis, back pain, and arthralgia. Less common but more serious side effects could involve allergic reactions or mood disturbances. It's crucial to follow your doctor's advice. If you experience any severe or persistent side effects, or if your sleep problems worsen, you should stop taking Circadin and consult your prescribing doctor immediately. Your Hi-Doctor physician can be reached via the private, auditable chat in your account.
