Melatonin

Melatonin, the active ingredient in Melatonin, is a melatonin receptor agonist presented as an oral formulation for oral use. It is used to manage insomnia, jet lag and sleep‑wake rhythm disorders in adults and children when appropriate.

The company adheres to stringent quality standards and provides regulatory documentation for import across EU, Asia and the Americas. Customers benefit from reliable batch consistency and responsive technical support.

Melatonin acts on the melatonin receptor pathway to regulate circadian rhythm disturbances.

- Insomnia: helps initiate and maintain sleep in individuals who have difficulty falling or staying asleep. - Jet lag: reduces the time required to adjust the sleep schedule after rapid east‑west travel. - Sleep‑wake rhythm disorder: stabilizes abnormal sleep patterns in shift‑work or delayed sleep phase syndrome.

Melatonin may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Headache - Dizziness - Daytime sleepiness - Nausea

Serious or Rare Side Effects: - Allergic reaction (rash, swelling, itching) - Severe depression or suicidal thoughts - Arrhythmia

When using melatonin, several precautions should be observed to ensure safety and effectiveness.

- Assess sleep patterns before initiating therapy: evaluate underlying causes of insomnia. - Review concomitant medications: identify potential interactions. - Use the lowest effective dose: start with minimal amount and adjust as needed. - Avoid operating machinery if drowsy: assess daytime alertness. - Monitor for allergic reactions: discontinue if rash or swelling occurs. - Store at room temperature: keep in original container, protect from moisture and direct light.

Melatonin can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): may increase bleeding risk. - Immunosuppressants (e.g., cyclosporine): may diminish immunosuppressive effect. - Sedative CNS depressants (e.g., benzodiazepines): may enhance sedation.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may alter hormone levels. - Antidiabetic agents: may affect blood glucose control. - Antihypertensives: may cause additive blood pressure lowering.
