What is Mizolastine?
Mizolastine, the active ingredient in Mizollen, is a antihistamine (H1 receptor antagonist) presented as an oral tablet for oral use. It treats allergic rhinitis, seasonal allergic rhinitis and urticaria in adults and children as prescribed. GNH USA supplies Mizollen as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Mizolastine used for?
Mizollen is an H1‑receptor antagonist that manages allergic conditions affecting the nasal passages and skin.
Allergic rhinitis: reduces nasal congestion, itching and sneezing associated with perennial allergies. Seasonal allergic rhinitis: alleviates symptoms triggered by pollen or other seasonal allergens. Urticaria: helps control itching and hives caused by chronic or acute urticaria.
What are the side effects of Mizolastine?
Mizollen may cause a range of adverse reactions, which are grouped by frequency and severity.
Common Side Effects: - Drowsiness: mild to moderate sedation, especially after the first doses. - Dry mouth: reduced salivation leading to a feeling of thirst. - Headache: transient head discomfort. - Fatigue: general sense of tiredness.
Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - Cardiac arrhythmia: irregular heart rhythm reported in rare cases. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
What precautions apply to Mizolastine?
When prescribing Mizollen, clinicians should consider the following precautions to ensure safe use.
Assess renal function: dose adjustment may be needed in severe renal impairment. Avoid in patients with known hypersensitivity to mizolastine or other H1 antagonists. Caution in the elderly: increased susceptibility to sedation and falls. Monitor for concomitant CNS depressants: additive drowsiness may occur. Store below 25°C: keep in the original pack, protect from moisture.
What does Mizolastine interact with?
Mizollen can interact with other medicines; awareness of the interaction level guides clinical decisions.
Major Interactions (Avoid): - Potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase mizolastine plasma concentrations leading to heightened side effects. - Monoamine oxidase inhibitors (MAOIs): concurrent use may enhance antihistaminic effects and cause excessive sedation.
Moderate Interactions (Monitor Closely): - Alcohol: additive central nervous system depression. - Other sedating antihistamines or CNS depressants: may increase drowsiness. - Theophylline: possible reduction in antihistamine efficacy.
