- Allergic rhinitis: reduces nasal congestion, sneezing, itching and watery eyes. - Seasonal allergic rhinitis: provides symptom relief during pollen exposure. - Chronic idiopathic urticaria: decreases frequency and severity of hives and associated itching.

Levocetirizine may cause adverse reactions, which are categorized by frequency.

Common Side Effects: - Headache: mild to moderate intensity. - Drowsiness: occasional sleepiness, especially at treatment initiation. - Dry mouth: reduced salivation. - Fatigue: general tiredness.

Serious or Rare Side Effects: - Angioedema: swelling of face, lips or tongue. - Anaphylactic reaction: severe, potentially life‑threatening hypersensitivity. - Stevens‑Johnson syndrome: rare severe skin eruption.

Before prescribing Levocetirizine, consider the following precautions. - Assess renal function: dose adjustment may be required in severe renal impairment. - Avoid in known hypersensitivity: discontinue if allergic reaction occurs. - Caution in hepatic impairment: monitor liver function tests. - Monitor sedation: advise patients not to operate machinery if drowsiness develops. - Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Levocetirizine can interact with other medicines; awareness of these interactions helps ensure safety.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors: may increase levocetirizine plasma levels. - Alcohol: can enhance sedative effects.

Moderate Interactions (Monitor Closely): - Central nervous system depressants (e.g., benzodiazepines): may increase drowsiness. - Theophylline: possible alteration of levocetirizine clearance. - Ritonavir: may raise levocetirizine concentrations.
