Melatonin

Melatonin, the active ingredient in Melatonin, is a melatonin receptor agonist presented as an oral supplement for oral use. It helps regulate the sleep‑wake cycle and promotes sleep onset in adults experiencing insomnia, jet lag, or circadian rhythm sleep disorders.

GNH USA supplies Melatonin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. All batches are manufactured under EU GMP standards and undergo rigorous quality testing before release. The product is distributed through a secure cold‑chain logistics network to maintain stability during transport.

Melatonin acts on the melatonin receptor pathway to address sleep‑related disorders.

Insomnia: improves sleep onset and duration in adults with difficulty falling asleep. Jet lag: helps realign circadian rhythm after rapid time‑zone travel. Circadian rhythm sleep disorders: supports normalization of sleep‑wake cycles in shift‑work or non‑24‑hour sleep‑wake disorder.

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

Common Side Effects: - Drowsiness or daytime sleepiness - Headache - Dizziness - Nausea or mild gastrointestinal discomfort - Vivid dreams - Mild fatigue

Serious or Rare Side Effects: - Allergic reactions such as rash, itching, or swelling - Severe dizziness or fainting - Mood changes including depression or anxiety - Abnormal heart rhythm or palpitations - Hallucinations or confusion - Severe gastrointestinal upset

Use melatonin with consideration of individual health status and potential interactions.

Assess sleep patterns before initiating therapy: confirm diagnosis of sleep disorder. Avoid concurrent alcohol consumption: may increase sedation. Monitor for daytime drowsiness: adjust timing if needed. Use caution in hepatic impairment: metabolism may be altered. Store at room temperature: keep in the original pack, protect from moisture and light.

Melatonin may interact with several medication classes.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): increased bleeding risk. - Immunosuppressants (e.g., cyclosporine): altered melatonin metabolism. - Central nervous system depressants (e.g., benzodiazepines): additive sedation.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may raise melatonin plasma levels. - Antidepressants (e.g., SSRIs): potential pharmacodynamic interaction. - Caffeine-containing products: may diminish melatonin effectiveness.
