Melatonin

Melatonin, the active ingredient in Melatonin, is a melatonin receptor agonist presented as a tablet for oral use. It assists adults with insomnia, other sleep disorders, and jet lag by supporting the natural sleep‑wake cycle. The compound interacts with specific brain receptors to help initiate and maintain sleep, offering a non‑prescription option for individuals experiencing difficulty falling asleep or adjusting to new time zones.

GNH USA supplies Melatonin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Melatonin is used to address disorders of the sleep‑wake cycle.

Insomnia: helps initiate sleep and improve sleep duration in adults with difficulty falling asleep. Sleep disorders: supports regulation of circadian rhythm in conditions such as delayed sleep phase syndrome. Jet lag: reduces the time needed to adjust to new time zones after rapid travel across multiple time zones.

Melatonin is generally well tolerated, but some users may experience adverse reactions.

Common Side Effects: - Headache: mild to moderate intensity. - Dizziness: transient sensation of light‑headedness. - Daytime sleepiness: feeling unusually drowsy after dosing. - Nausea: occasional stomach upset. - Vivid dreams: unusually intense or memorable dreams. - Mild gastrointestinal discomfort: bloating or mild cramps.

Serious or Rare Side Effects: - Allergic reactions: rash, itching, or swelling. - Severe dizziness or vertigo: may indicate central nervous system involvement. - Mood changes: depression or anxiety exacerbation. - Hallucinations: visual or auditory disturbances. - Severe depression or suicidal thoughts: rare but reported. - Abnormal heart rhythm: palpitations or arrhythmia.

Before using melatonin, consider the following safety measures.

Assess sleep pattern: evaluate underlying causes of sleep disturbance before initiating therapy. Avoid driving: potential drowsiness may impair motor skills. Limit alcohol: concurrent intake can increase sedation. Use lowest effective dose: minimizes risk of side effects. Consult healthcare provider if pregnant or breastfeeding: safety data are limited. Store at room temperature: keep in the original pack, protect from moisture and light.

Melatonin can interact with several medication classes; awareness helps mitigate risks.

Major Interactions (Avoid): - Anticoagulants: may increase bleeding risk. - Immunosuppressants (e.g., cyclosporine): may reduce melatonin clearance. - CNS depressants (e.g., benzodiazepines): additive sedation. - Fluoroquinolone antibiotics: may alter melatonin metabolism. - Hormonal contraceptives: may affect hormone balance.

Moderate Interactions (Monitor Closely): - Antidepressants (SSRIs): possible serotonin syndrome. - Antihypertensives: may enhance blood‑pressure‑lowering effect. - Caffeine: may counteract sleep‑promoting action. - Beta‑blockers: may increase endogenous melatonin levels. - Vaccines: theoretical immunomodulation requiring observation.
