What is Melatonin?
Melatonin, the active ingredient in Melatonin Pharma Nord, is a hormone presented as an oral tablet for oral use. It regulates the circadian rhythm and supports normal sleep patterns in adults with sleep‑wake disturbances, including jet lag, shift‑work disorder and delayed sleep phase syndrome.
GNH USA supplies Melatonin Pharma Nord as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable sourcing, regulatory support and consistent product quality across multiple markets.
What is Melatonin used for?
Melatonin acts on the melatonin receptor pathway to help normalize sleep‑wake cycles.
Jet lag: reduces the time needed to adjust to new time zones. Shift work disorder: improves sleep quality for workers with irregular schedules. Delayed sleep phase syndrome: advances sleep onset time in individuals with late‑night sleep preference. Insomnia (occasional): may aid in falling asleep for short‑term sleep difficulty. Elderly sleep disturbances: supports sleep maintenance in older adults.
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 - Mild gastrointestinal discomfort
Serious or Rare Side Effects: - Allergic reaction (rash, itching, swelling) - Severe skin eruption (Stevens‑Johnson syndrome) - Mood changes or depression - Seizures (rare) - Hormonal imbalance with prolonged high‑dose use
What precautions apply to Melatonin?
When using melatonin, consider the following safety measures.
Assess suitability: evaluate underlying sleep disorders before initiation. Avoid operating machinery: refrain from driving or using heavy equipment if drowsy. Caution in hepatic impairment: dose may need adjustment in liver disease. Use in children only under medical supervision. Interaction with anticoagulants: monitor bleeding risk when combined. Store below 25°C: keep in the original pack, protect from moisture.
What does Melatonin interact with?
Melatonin can interact with several medication classes.
Major Interactions (Avoid): - Central nervous system depressants (e.g., benzodiazepines, barbiturates): additive sedation. - Anticoagulants (e.g., warfarin): potential increase in bleeding risk. - Immunosuppressants (e.g., cyclosporine): may reduce immunosuppressive effect.
Moderate Interactions (Monitor Closely): - Oral contraceptives: possible alteration of hormone levels. - Antihypertensives: may enhance blood‑pressure‑lowering effect. - Antidepressants (SSRIs, SNRIs): monitor for serotonin‑related side effects.
