Melatonine Tiofarma (Melatonin)

Melatonine Tiofarma acts on melatonin receptors to regulate the sleep‑wake cycle and is indicated for several sleep‑related conditions.

• Insomnia: helps initiate and maintain sleep in individuals with difficulty falling or staying asleep.
• Sleep‑wake rhythm disorders: assists in synchronising abnormal circadian rhythms such as shift‑work disorder.
• Jet lag: reduces the time needed to adjust to new time zones after long‑distance travel.

• Melatonin binds as an agonist to MT1 and MT2 receptors in the suprachiasmatic nucleus, mimicking endogenous melatonin. Activation of these G‑protein‑coupled receptors modulates circadian signalling, promotes the onset of sleep, and helps re‑align the internal biological clock with external light‑dark cycles.

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

Common Side Effects

• Headache: mild to moderate pain often resolving without treatment.
• Dizziness: sensation of light‑headedness, especially after first doses.
• Daytime sleepiness: residual drowsiness that may affect alertness.
• Nausea: mild stomach upset or queasiness.
• Vivid dreams: unusually intense or memorable dreaming.
• Mild gastrointestinal discomfort: occasional abdominal cramps or loose stools.

Serious or Rare Side Effects

• Allergic reactions: rash, itching, swelling, or angioedema requiring medical attention.
• Depression or mood changes: emergence of depressive symptoms in susceptible individuals.
• Seizures: rare occurrence, particularly in patients with a history of epilepsy.
• Severe hypersensitivity: anaphylactic reactions demanding immediate emergency care.
• Abnormal heart rhythm: rare cases of arrhythmia reported.

When considering Melatonine Tiofarma, several safety measures should be observed.

• Assess sleep hygiene: ensure non‑pharmacologic sleep practices are in place before use.
• Use lowest effective dose: start with the minimal dose that provides benefit.
• Avoid operating machinery: refrain from driving or using heavy equipment if daytime drowsiness occurs.
• Contraindication: do not use in individuals with known hypersensitivity to melatonin.
• Caution in hepatic impairment: monitor liver function and adjust therapy as needed.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Melatonin can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• CNS depressants (e.g., benzodiazepines, barbiturates): may increase sedation and impair alertness.
• Anticoagulants (e.g., warfarin): melatonin may enhance anticoagulant effect, raising bleeding risk.
• Immunosuppressants (e.g., cyclosporine): potential reduction in immunosuppressive activity.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: melatonin may reduce contraceptive effectiveness; monitor cycle changes.
• Antihypertensives: additive blood‑pressure‑lowering effect may require dose adjustment.
• CYP1A2 inhibitors (e.g., fluvoxamine): can raise melatonin plasma levels, increasing side‑effect potential.
