Melatonin Vitabalans (Melatonin)

Melatonin acts on the melatonin receptor pathway to help normalize sleep patterns.

• Insomnia: assists adults in falling asleep more quickly and improving sleep continuity.
• Jet lag: reduces the time needed to adjust to new time zones after long‑distance travel.
• Circadian rhythm sleep disorders: helps align the internal clock for shift‑work or delayed‑sleep‑phase patients.

• Melatonin binds as an agonist to MT1 and MT2 receptors located in the suprachiasmatic nucleus of the hypothalamus. Activation of these G‑protein‑coupled receptors modulates intracellular cyclic AMP levels, thereby influencing the circadian timing system and facilitating the transition to sleep by signaling darkness to the body.

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

Common Side Effects

• Headache: mild to moderate discomfort often resolving without intervention.
• Dizziness: transient sensation of light‑headedness, especially after initial dosing.
• Daytime sleepiness: residual drowsiness if taken too late in the evening.
• Nausea or mild gastrointestinal upset.

Serious or Rare Side Effects

• Allergic reactions: rash, itching, or swelling that may require medical attention.
• Vivid dreams or nightmares: unusual sleep‑related imagery.
• Mood changes: irritability or depressive symptoms in susceptible individuals.
• Severe dizziness or fainting: may indicate hypotension.
• Hallucinations: rare perceptual disturbances requiring immediate evaluation.

Before using Melatonin, consider the following safety measures.

• Assess underlying sleep disorder: confirm diagnosis to ensure appropriate use.
• Hypersensitivity: avoid if known allergy to melatonin or excipients.
• Concomitant CNS depressants: use caution when combined with sedatives or alcohol.
• Pediatric use: not recommended for children unless specifically prescribed.
• Hormonal considerations: monitor patients with endocrine disorders for potential effects.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Melatonin can interact with several medication classes; awareness helps minimize risk.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): may increase bleeding tendency.
• Immunosuppressants (e.g., cyclosporine): potential alteration of drug levels.
• Central nervous system depressants (e.g., benzodiazepines): additive sedative effect.

Moderate Interactions (Monitor Closely):\n- Oral contraceptives: melatonin may reduce contraceptive efficacy.

• Antidepressants (e.g., SSRIs): possible increase in side‑effect intensity.
• Antihypertensives: may enhance blood‑pressure‑lowering effects.
