Hydroxyzine Hydrochloride Ipca Laboratories Uk (Hydroxyzine Hydrochloride)

Hydroxyzine Hydrochloride is a first‑generation antihistamine that acts on peripheral H1 receptors to relieve a range of conditions.

• Allergic skin conditions and pruritus: reduces itching and skin inflammation.
• Anxiety and tension: provides calming effects and reduces nervousness.
• Peri‑operative sedation: induces sedation before or after surgery.
• Nausea and vomiting: helps control these symptoms in various clinical settings.

• Hydroxyzine Hydrochloride selectively antagonizes peripheral histamine H1 receptors, preventing histamine‑mediated allergic responses. It also exhibits anticholinergic activity and central nervous system depressant effects, contributing to its sedative and anti‑emetic properties. The drug is absorbed orally and metabolized primarily in the liver before renal excretion.

Hydroxyzine Hydrochloride may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

• Drowsiness: feeling unusually sleepy or fatigued.
• Dry mouth: reduced salivation leading to throat discomfort.
• Blurred vision: temporary visual disturbances.
• Constipation: slowed gastrointestinal motility.
• Headache: mild to moderate head pain.
• Dizziness: sensation of light‑headedness.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction with airway compromise.
• Cardiac arrhythmia: irregular heart rhythm, including QT prolongation.
• Seizures: rare occurrence of convulsive episodes.
• Hepatic dysfunction: signs of liver injury such as jaundice.
• Blood dyscrasias: abnormal blood cell counts.
• Prolonged QT interval: risk of serious ventricular tachyarrhythmias.

Hydroxyzine Hydrochloride requires careful consideration of patient history and concurrent conditions.

• Assess patient history: evaluate for glaucoma, urinary retention, or prostate enlargement.
• Avoid in hypersensitivity: do not use if the patient has known allergy to hydroxyzine or related compounds.
• Use caution in the elderly: increased susceptibility to sedation and anticholinergic effects.
• Monitor hepatic function: adjust use if significant liver impairment is present.
• Avoid concurrent CNS depressants: may enhance sedation and respiratory depression.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Hydroxyzine Hydrochloride can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Alcohol: additive central nervous system depression leading to profound sedation.
• Opioids: synergistic sedation and potential respiratory depression.
• Other antihistamines: increased anticholinergic burden and excessive drowsiness.

Moderate Interactions (Monitor Closely)

• Anticholinergic agents: heightened dry mouth, constipation, and blurred vision.
• QT‑prolonging drugs: increased risk of cardiac arrhythmias.
• Theophylline: possible elevation of plasma theophylline concentrations.
