Melatonina Bluefish

Melatonin, the active ingredient in Melatonina Bluefish, is a melatonin receptor agonist presented as an oral formulation for oral use. It is used to help regulate the sleep‑wake cycle and to promote the onset of sleep in individuals experiencing insomnia or circadian rhythm disturbances. By binding to MT1 and MT2 receptors in the suprachiasmatic nucleus, it supports the natural circadian rhythm, facilitating sleep initiation and maintenance in adults and older children.

GNH USA supplies Melatonina Bluefish 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: facilitates sleep onset and improves sleep continuity. - Sleep‑wake rhythm disorders: helps align the internal clock to a regular pattern. - Shift work disorder: reduces excessive sleepiness and improves alertness during scheduled work periods.

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

Common Side Effects: - Headache: mild to moderate pain often reported after ingestion. - Dizziness: transient sensation of light‑headedness. - Daytime sleepiness: residual drowsiness after nighttime dosing. - Nausea: occasional gastrointestinal discomfort.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, or angioedema requiring medical attention. - Mood changes: emergence or worsening of depression or anxiety. - Seizure: rare occurrence, particularly in individuals with a pre‑existing seizure disorder.

When using melatonin, consider the following precautions.

- Pregnancy: safety not established; consult a healthcare professional before use. - Breastfeeding: unknown effects on the infant; weigh potential benefits against risks. - Age: use with caution in children and adolescents; dosing should be individualized. - Concomitant medications: review potential interactions with sedatives, anticoagulants, and hormonal therapies. - Medical conditions: exercise caution in patients with depression, seizure disorders, or autoimmune diseases. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture and light.

Melatonin may interact with other medicines; monitor accordingly.

Major Interactions (Avoid): - Warfarin: melatonin may increase anticoagulant effect and alter INR. - Sedative CNS depressants (e.g., benzodiazepines, barbiturates): combined use can enhance drowsiness and impair coordination.

Moderate Interactions (Monitor Closely): - Antidepressants (SSRIs, MAOIs): may affect melatonin metabolism and alter therapeutic response. - CYP1A2 inhibitors (cimetidine, fluvoxamine): can raise melatonin plasma concentrations. - Oral contraceptives: may modify melatonin clearance, potentially requiring dose adjustment.
