Hydroxyzine Cristers

Hydroxyzine, the active ingredient in Hydroxyzine Cristers, is a first‑generation H1 antihistamine presented as an oral tablet for oral use. It is used to relieve allergic symptoms, manage anxiety, and provide sedation before procedures.

GNH USA supplies Hydroxyzine Cristers as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Hydroxyzine acts on allergic and anxiety‑related pathways to alleviate symptoms.

- Allergic rhinitis: reduces nasal congestion, itching and sneezing. - Urticaria: diminishes hives and associated itching. - Pruritus: provides relief from generalized itching. - Anxiety: alleviates tension and nervousness. - Sedation before surgical procedures: induces calmness and drowsiness for pre‑operative comfort.

Hydroxyzine may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Drowsiness: feeling unusually sleepy or fatigued. - Dry mouth: reduced salivation leading to a parched sensation. - Blurred vision: temporary difficulty focusing. - Constipation: slowed intestinal motility. - Headache: mild to moderate head discomfort. - Dizziness: sensation of light‑headedness or unsteadiness.

Serious or Rare Side Effects: - Tachycardia: abnormally rapid heart rate. - Severe hypotension: marked drop in blood pressure. - Arrhythmia: irregular heart rhythm. - Anaphylaxis: life‑threatening allergic reaction. - Seizures: uncontrolled electrical activity in the brain. - Hepatic dysfunction: abnormal liver enzyme elevations.

Before using Hydroxyzine, consider the following safety measures.

- Pregnancy: safety not established; use only if benefit outweighs risk. - Elderly patients: increased sensitivity to sedation; start with low dose. - Driving or operating machinery: may impair alertness; avoid hazardous tasks. - Concomitant CNS depressants: risk of additive sedation; monitor closely. - Store at room temperature: keep in original container, protect from moisture and light.

Hydroxyzine can interact with several medication classes.

Major Interactions (Avoid): - CNS depressants (e.g., alcohol, benzodiazepines): additive sedation and respiratory depression. - Monoamine oxidase inhibitors (MAOIs): risk of severe hypotension and syncope. - Anticholinergic agents (e.g., atropine): heightened anticholinergic burden.

Moderate Interactions (Monitor Closely): - Antihypertensives: may enhance blood‑pressure‑lowering effects. - Theophylline: hydroxyzine can increase plasma theophylline concentrations. - CYP3A4 inhibitors: may raise hydroxyzine levels, requiring dose adjustment.
