Levocetirine, a second‑generation antihistamine, acts on histamine‑mediated allergic pathways to alleviate symptoms.

Allergic rhinitis: reduces nasal congestion, sneezing, itching and rhinorrhea. Chronic idiopathic urticaria: decreases frequency and severity of hives and itching. Allergic conjunctivitis: helps relieve ocular itching and tearing.

Levocetirine may cause adverse reactions, which are generally mild but can be serious in rare cases.

Common Side Effects: - Headache - Dry mouth - Drowsiness - Fatigue - Nausea - Altered taste perception

Serious or Rare Side Effects: - Angioedema or severe swelling of the face, lips or throat - Severe skin reactions such as Stevens‑Johnson syndrome or toxic epidermal necrolysis - Anaphylactic reaction requiring immediate medical attention - Elevation of liver enzymes or hepatic dysfunction - Blood dyscrasias including neutropenia or thrombocytopenia - Cardiac arrhythmias in susceptible individuals

Before initiating therapy, consider the following safety measures.

Assess renal function: dose may need adjustment in severe renal impairment. Avoid use in patients with known hypersensitivity to levocetirizine or other antihistamines. Caution in hepatic impairment: monitor liver function tests periodically. Monitor for excessive sedation if combined with alcohol or CNS depressants. Pregnancy and lactation: consult a healthcare professional before use. Store below 25°C: keep in the original pack, protect from moisture.

Levocetirine can interact with other substances; awareness helps minimize risk.

Major Interactions (Avoid): - Alcohol and other CNS depressants: may increase drowsiness and impair cognition. - Concurrent use with other antihistamines: risk of additive sedation.

Moderate Interactions (Monitor Closely): - Theophylline: may increase plasma concentrations of levocetirine. - Strong CYP3A4 inhibitors such as ritonavir: may raise levocetirine levels. - Ketoconazole: potential increase in exposure requiring clinical monitoring.
