Hydroxyzine-2hcl Ucb Pharma (Hydroxyzine Hydrochloride)

Hydroxyzine Hydrochloride is a first‑generation antihistamine that acts on peripheral H1 receptors to alleviate a range of allergic and related conditions.

• Allergic skin conditions: reduces itching and inflammation associated with urticaria or dermatitis.
• Pruritus: provides relief from generalized itching not caused by infection.
• Anxiety: produces calming effects that help manage mild to moderate anxiety.
• Sedation: induces sleepiness useful for short‑term insomnia or pre‑procedural calming.
• Nausea: alleviates nausea and vomiting related to allergic reactions or motion sickness.

• Hydroxyzine Hydrochloride selectively antagonizes peripheral H1 histamine receptors, preventing histamine‑mediated vasodilation, increased vascular permeability, and sensory nerve stimulation. Its central anticholinergic activity contributes to sedative and anxiolytic effects, while peripheral blockade reduces pruritic and allergic responses.

Hydroxyzine Hydrochloride may cause a variety of adverse reactions, ranging from mild to serious.

Common Side Effects

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

Serious or Rare Side Effects

• Tachycardia or arrhythmia: abnormal heart rhythms.
• Severe hypotension: marked drop in blood pressure.
• Anaphylaxis: life‑threatening allergic reaction.
• Seizures: convulsive episodes.
• Hepatic dysfunction: abnormal liver enzyme elevations.
• Neuroleptic malignant‑like syndrome: rare but severe muscle rigidity and fever.

Before prescribing Hydroxyzine Hydrochloride, clinicians should consider several safety measures.

• Assess hepatic function: adjust use in patients with severe liver impairment.
• Monitor sedation: caution patients when operating machinery or driving.
• Avoid use in known hypersensitivity: discontinue if allergic reaction occurs.
• Use with caution in the elderly: increased anticholinergic effects may lead to confusion.
• Pregnancy and lactation: consult a physician before use; benefits must outweigh risks.
• Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Hydroxyzine Hydrochloride can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• CNS depressants (e.g., benzodiazepines, opioids): additive sedation and respiratory depression.
• Alcohol: markedly increased drowsiness and impaired coordination.
• Anticholinergic agents: heightened anticholinergic burden leading to confusion and dry mouth.

Moderate Interactions (Monitor Closely)

• Antihypertensives: possible enhancement of hypotensive effect.
• MAO inhibitors: potential for QT interval prolongation.
• Theophylline: hydroxyzine may increase plasma concentrations of theophylline.
