What is Melatonin?
Melatonin, the active ingredient in Melatonine Pharma Nord, is a melatonin receptor agonist presented as an oral dosage form for oral use. It is used to help regulate sleep timing in individuals with insomnia, jet lag, or circadian rhythm disturbances. GNH USA supplies Melatonine Pharma Nord as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Melatonin used for?
Melatonin acts on the melatonin receptor pathway to regulate sleep timing.
Insomnia: helps initiate sleep and improve sleep continuity in adults who have difficulty falling asleep. Jet lag: reduces the time needed to adjust to new time zones and alleviates associated fatigue. Sleep-wake rhythm disorders: supports alignment of the circadian rhythm in shift‑work or 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 - Dizziness - Daytime sleepiness - Nausea - Vivid dreams
Serious or Rare Side Effects: - Allergic reaction (rash, swelling, difficulty breathing) - Severe rash or Stevens‑Johnson syndrome - Mood changes including depression or suicidal thoughts - Rare cardiac arrhythmias
What precautions apply to Melatonin?
Use melatonin with consideration of individual health status and potential interactions. - Assess sleep pattern before initiating therapy: confirm that insomnia is not due to an underlying medical condition. - Avoid use with shift‑work schedules unless directed by a clinician. - Monitor for excessive daytime drowsiness, especially when driving or operating machinery. - Caution in patients with a history of depression or mood disorders. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.
What does Melatonin interact with?
Melatonin may interact with other medicines; review patient medication lists.
Major Interactions (Avoid): - Concurrent use with central nervous system depressants (e.g., benzodiazepines) may increase sedation. - Interaction with anticoagulants such as warfarin may alter bleeding risk.
Moderate Interactions (Monitor Closely): - Fluvoxamine can raise melatonin plasma concentrations. - Caffeine may diminish melatonin’s sleep‑promoting effect. - Antihypertensive agents may experience additive blood‑pressure‑lowering effects.
