Hydroxyzine Zentiva

Hydroxyzine, the active ingredient in Hydroxyzine Zentiva, is an antihistamine presented as an oral tablet for systemic use. It blocks peripheral H1 receptors and is employed to relieve allergic rhinitis, control pruritus, reduce anxiety, and provide pre‑operative sedation in both adult and pediatric patients as directed by a healthcare professional.

GNH USA supplies Hydroxyzine Zentiva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU GMP standards and provides batch‑tested products with full documentation for regulatory review.

Hydroxyzine is an antihistamine that acts on peripheral H1 receptors to manage several allergic and related conditions.

Allergic rhinitis: reduces nasal congestion, sneezing and itching associated with seasonal or perennial allergies. Pruritus: alleviates itching caused by dermatologic disorders such as urticaria. Anxiety: provides short‑term relief of anxiety symptoms in adults. Pre‑operative sedation: produces calming effect before surgical or diagnostic procedures. Nausea: helps control nausea and vomiting in certain clinical settings.

Hydroxyzine may cause a range of adverse reactions. Monitoring for side effects is recommended, especially during dose titration.

Common Side Effects: - Drowsiness - Dry mouth - Dizziness - Blurred vision

Serious or Rare Side Effects: - Cardiac arrhythmia - Severe hypotension - Stevens‑Johnson syndrome

Hydroxyzine requires careful use in specific populations and clinical situations.

Pregnancy: safety not established; avoid unless benefit outweighs risk. Breastfeeding: unknown excretion; consider alternatives. Elderly: increased sensitivity to sedation and anticholinergic effects. Concomitant CNS depressants: may enhance drowsiness and respiratory depression. Renal or hepatic impairment: dose adjustment may be necessary. Store at ambient temperature below 25°C: keep in original container, protect from moisture and light.

Hydroxyzine can interact with several drug classes, altering its efficacy or safety profile.

Major Interactions (Avoid): - Monoamine oxidase inhibitors: risk of severe hypotension. - CNS depressants (benzodiazepines, opioids): additive sedation and respiratory depression. - Anticholinergic agents: increased anticholinergic burden.

Moderate Interactions (Monitor Closely): - Alcohol: may enhance drowsiness. - CYP3A4 inhibitors (e.g., ketoconazole): may raise hydroxyzine plasma levels.
