Indications & Clinical Uses

Melnite is a melatonin receptor agonist that acts on the circadian rhythm pathway to improve sleep quality.

  • Jet lag: helps adjust the internal clock after rapid time‑zone travel, reducing sleep disturbances.
  • Delayed sleep phase disorder: advances sleep onset time, facilitating earlier bedtime.
  • Primary insomnia: supports the initiation and maintenance of sleep in adults with difficulty falling or staying asleep.

How It Works

  • Melatonin binds to MT1 and MT2 receptors in the suprachiasmatic nucleus, mimicking the endogenous hormone. Activation of these G‑protein‑coupled receptors modulates circadian signaling, promoting the onset of sleep and synchronizing the body's internal clock with environmental light‑dark cycles.

Side Effects

Melatonin is generally well tolerated, but adverse reactions can occur.

Common Side Effects

  • Headache: mild to moderate pain often reported after ingestion.
  • Dizziness: transient sensation of light‑headedness.
  • Daytime sleepiness: residual drowsiness if taken too late.
  • Nausea: occasional stomach upset.
  • Irritability: mild mood changes in some users.

Serious or Rare Side Effects

  • Allergic reaction: rash, itching, or swelling indicating hypersensitivity.
  • Severe depression: worsening mood in predisposed individuals.
  • Seizures: rare neurologic events reported in isolated cases.
  • Hallucinations: uncommon visual or auditory disturbances.

Precautions & Warnings

When considering melatonin therapy, several safety measures are recommended.

  • Assess renal function: adjust use in patients with severe kidney impairment.
  • Avoid use in children without medical supervision: pediatric safety data are limited.
  • Consider timing of administration: take 30‑60 minutes before desired bedtime.
  • Monitor for mood changes: watch for signs of depression or anxiety.
  • Store at room temperature: keep in the original pack, protect from moisture and direct sunlight.

Avoid Interactions

Melatonin can interact with other medicines, altering their effects or safety profile.

Major Interactions (Avoid)

  • Warfarin: melatonin may increase anticoagulant effect and bleeding risk.
  • Cyclosporine: potential alteration of immunosuppressant levels.
  • Benzodiazepines: additive central nervous system depression may enhance sedation.

Moderate Interactions (Monitor Closely)

  • Caffeine: may diminish melatonin's sleep‑promoting effect.
  • Oral contraceptives: possible impact on hormone metabolism.
  • SSRIs (e.g., fluoxetine): may increase serotonergic activity, raising risk of serotonin‑related effects.

Frequently Asked Questions

Melnite contains melatonin, which is used to help regulate the sleep‑wake cycle. It is commonly employed for conditions such as jet lag, delayed sleep phase disorder, and primary insomnia, supporting the initiation and maintenance of sleep.

Melatonin acts as an agonist at MT1 and MT2 receptors in the brain’s suprachiasmatic nucleus. By binding these receptors, it mimics the natural hormone released at night, signaling the body that it is time to sleep and helping to synchronize circadian rhythms.

The appropriate dose of Melnite is determined by a qualified prescriber based on the individual’s age, condition, and response. Healthcare professionals tailor the regimen to achieve the desired therapeutic effect while minimizing potential side effects.

Safety data for melatonin 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 using Melnite.

To request Melnite, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will verify trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Unlike many prescription hypnotics, melatonin works by aligning the body’s internal clock rather than directly depressing the central nervous system. This mechanism often results in fewer next‑day residual effects, making it a preferred option for circadian‑related sleep disturbances such as jet lag.

Melnite should be stored at room temperature, below 25 °C. Keep the product in its original container, protect it from moisture and direct sunlight, and ensure the packaging remains sealed until use.

Melnite is taken orally, typically 30‑60 minutes before the desired bedtime. The tablet or capsule should be swallowed whole with a glass of water and not chewed or broken, unless otherwise directed by a healthcare professional.

Serious risks, though rare, include allergic reactions such as rash, itching or swelling, and potential worsening of depression or mood disorders. Individuals experiencing these symptoms should seek immediate medical attention.

Melnite is not recommended for individuals with known hypersensitivity to melatonin, those with severe renal impairment without medical supervision, or children unless specifically prescribed. Pregnant or breastfeeding women should consult their physician before use.
