What is Mizolastine?
Mizolastine, the active ingredient in Mizollen, is a second‑generation H1 antihistamine presented as an oral tablet for oral use. It alleviates symptoms of allergic rhinitis, urticaria and related allergic conditions in adults and adolescents.
GNH USA supplies Mizollen as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Mizolastine used for?
Mizolastine is used to manage allergic conditions mediated by histamine release.
Allergic rhinitis: reduces nasal congestion, sneezing, itching and watery discharge. Urticaria: relieves hives and associated itching. Allergic conjunctivitis: helps control eye itching, redness and tearing.
What are the side effects of Mizolastine?
Mizollen may cause adverse reactions that vary in frequency and severity.
Common Side Effects: - Drowsiness: mild to moderate sedation, especially after the first doses. - Headache: transient tension‑type headache. - Dry mouth: reduced salivation causing mild discomfort. - Fatigue: feeling of reduced energy or tiredness.
Serious or Rare Side Effects: - Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention. - Angioedema: rapid swelling of face, lips or throat. - Anaphylactic reaction: life‑threatening systemic allergic response.
What precautions apply to Mizolastine?
Before prescribing Mizollen, clinicians should consider several safety aspects.
Assess liver function: adjust use if hepatic impairment is present. Avoid driving or operating machinery: drowsiness may impair alertness. Use caution in renal impairment: monitor for accumulation. Not recommended for children under 12 years: safety not established. Avoid concomitant CNS depressants: may increase sedation. Store at ambient temperature: keep in the original pack, protect from moisture.
What does Mizolastine interact with?
Mizollen can interact with other medicines; awareness of the interaction level helps manage risk.
Major Interactions (Avoid): - MAO inhibitors: risk of hypertensive crisis. - Other antihistamines: additive sedation and anticholinergic effects. - QT‑prolonging drugs: potential for cardiac arrhythmias.
Moderate Interactions (Monitor Closely): - Alcohol: may enhance drowsiness. - Strong CYP3A4 inhibitors (e.g., ketoconazole): increase mizolastine plasma levels. - CYP3A4 inducers (e.g., rifampicin): reduce therapeutic effect.
