Levocetirizine is an H1 antihistamine that acts on allergic and urticarial conditions. - Allergic rhinitis: reduces nasal congestion, sneezing, itching and rhinorrhea. - Seasonal allergic rhinitis: alleviates symptoms triggered by pollen or seasonal allergens. - Chronic idiopathic urticaria: diminishes wheal formation, itching and hives, improving quality of life.

Levocetirizine is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Drowsiness: mild to moderate sleepiness, especially at treatment initiation. - Fatigue: a feeling of reduced energy. - Dry mouth: decreased salivation. - Headache: mild to moderate cranial pain. - Nausea: occasional stomach upset.

Serious or Rare Side Effects: - Angioedema: swelling of face, lips or tongue requiring urgent care. - Severe skin rash or Stevens‑Johnson syndrome: extensive epidermal detachment. - Anaphylaxis: rapid onset of systemic allergic reaction. - Hepatic dysfunction: abnormal liver enzymes. - Thrombocytopenia: low platelet count with potential bleeding risk.

Before initiating therapy, consider patient‑specific factors and safety measures. - Pregnancy: consult a healthcare professional before use; risk‑benefit assessment is required. - Renal impairment: evaluate renal function; dose adjustment may be necessary. - Elderly patients: monitor for increased sedation or confusion. - Driving or operating machinery: avoid until individual response to the drug is known. - Concomitant medications: review all current drugs for potential interactions. - Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levocetirizine may interact with other substances that affect the central nervous system or its metabolism.

Major Interactions (Avoid): - Alcohol: can potentiate sedation and impair cognition. - CNS depressants (e.g., benzodiazepines, barbiturates): additive drowsiness. - Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase levocetirizine plasma concentrations.

Moderate Interactions (Monitor Closely): - Ritonavir: may raise drug levels, requiring observation. - Erythromycin: potential modest increase in exposure. - Diphenhydramine or other antihistamines: risk of cumulative anticholinergic effects.
