What is Melatonin?
Melatonin, the active ingredient in Melatonin Pharma Nord, is a melatonin receptor agonist presented as an oral formulation for oral use. It is used to help regulate circadian rhythm and promote sleep onset in adults experiencing insomnia or sleep‑wake rhythm disorders.
GNH USA supplies Melatonin Pharma Nord as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Melatonin used for?
Melatonin acts on melatonin MT1 and MT2 receptors to support normal sleep physiology. It is indicated for the following conditions: - Insomnia: helps initiate sleep and improve sleep quality in individuals with difficulty falling asleep. - Sleep‑wake rhythm disorders: assists in realigning disrupted circadian rhythms such as delayed sleep phase syndrome.
What are the side effects of Melatonin?
Melatonin is generally well tolerated, but adverse reactions can occur.
Common Side Effects: - Headache: mild to moderate intensity. - Dizziness: transient sensation of light‑headedness. - Daytime sleepiness: occasional residual drowsiness. - Nausea: mild gastrointestinal upset. - Vivid dreams: occasional unusual dreaming patterns.
Serious or Rare Side Effects: - Allergic reaction: rash, itching, or swelling. - Severe rash: potentially indicative of hypersensitivity. - Mood changes: depression or irritability. - Hallucinations: rare perceptual disturbances. - Cardiac arrhythmia: abnormal heart rhythm in susceptible individuals.
What precautions apply to Melatonin?
When considering melatonin therapy, several precautions should be observed. - Assess renal function: adjust use in patients with severe renal impairment. - Avoid concurrent CNS depressants: may increase sedation. - Caution in shift‑work schedules: may affect circadian adjustment. - Pregnancy safety unknown: use only if clearly needed. - Breastfeeding: limited data, consider risk‑benefit. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.
What does Melatonin interact with?
Melatonin may interact with other medicines; awareness of interaction severity is important.
Major Interactions (Avoid): - CNS depressants (e.g., benzodiazepines): increased sedation risk. - Anticoagulants (e.g., warfarin): potential alteration of INR. - Immunosuppressants (e.g., cyclosporine): may affect drug metabolism.
Moderate Interactions (Monitor Closely): - SSRIs and other antidepressants: possible elevation of melatonin levels. - Oral contraceptives: may increase circulating melatonin. - Caffeine-containing products: may diminish melatonin efficacy.
