Melatonin

Melatonin works by binding to MT1 and MT2 receptors in the brain’s suprachiasmatic nucleus, the primary regulator of circadian rhythms. This receptor activation signals the body that it is nighttime, promoting the onset of sleep and helping to synchronize the sleep‑wake cycle with environmental light‑dark patterns.

The appropriate dose of melatonin is determined by a qualified healthcare professional based on the patient’s age, condition, and response to therapy. Dosing may vary widely, and patients should follow the prescriber’s instructions without self‑adjusting the amount.

Safety data for melatonin use in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before starting melatonin therapy.

To order melatonin, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide. After the request, the sales team will verify institutional credentials, then provide pricing, availability, shipping details and any necessary import documentation.

Unlike many prescription hypnotics that act on GABA receptors, melatonin works by mimicking the body’s natural hormone to regulate circadian timing. This mechanism generally results in fewer central nervous system side effects, but its efficacy may be limited to disorders related to clock misalignment rather than severe insomnia that requires stronger sedative agents.

Melatonin should be stored at room temperature, below 25 °C, in its original packaging. Keep the product away from moisture, direct sunlight, and excessive heat. Ensure the container is tightly closed to maintain potency throughout its shelf life.

Melatonin is taken orally, typically as a tablet, capsule, or liquid formulation. It is usually taken shortly before the intended bedtime, allowing the hormone to signal the body that it is time to sleep. Exact timing and method should follow the prescribing clinician’s guidance.

Serious risks, though rare, include severe allergic reactions such as rash, swelling, or itching, as well as mood disturbances like depression or suicidal thoughts. Cardiovascular effects such as arrhythmia have also been reported. Patients experiencing any of these symptoms should discontinue use and seek immediate medical attention.

Melatonin should be avoided by individuals with known hypersensitivity to the product, those taking certain medications that may interact severely (e.g., anticoagulants, immunosuppressants, or CNS depressants without medical supervision), and patients with uncontrolled psychiatric disorders unless specifically directed by a physician.
