Levocetirizine Teva

Levocetirizine, the active ingredient in Levocetirizine Teva, is an antihistamine presented as an oral dosage form for oral use. It is indicated for relief of symptoms associated with allergic rhinitis and chronic idiopathic urticaria in adults and children. GNH USA supplies Levocetirizine Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levocetirizine acts on histamine‑mediated allergic conditions, providing symptom control across several related disorders. Allergic rhinitis: alleviates sneezing, nasal discharge, itching and congestion. Chronic idiopathic urticaria: reduces the number and severity of hives and associated itching. Allergic conjunctivitis: eases eye itching, redness and watery discharge.

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

Common Side Effects: - Drowsiness or mild sedation. - Headache. - Dry mouth. - Nausea. - Dizziness. - Fatigue.

Serious or Rare Side Effects: - Angioedema or severe swelling of the face, lips, or tongue. - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Anaphylactic reactions. - Cardiac arrhythmias or prolonged QT interval. - Hepatic injury (rare). - Severe hypersensitivity reactions.

Before initiating therapy, consider the following safety measures. - Renal function assessment: dose adjustment may be required in severe renal impairment. - Alcohol avoidance: concurrent use can increase sedation. - Pregnancy caution: use only if the potential benefit justifies the potential risk to the fetus. - Lactation caution: levocetirizine is excreted in breast milk; weigh benefits against possible effects on the infant. - Cardiac monitoring: patients with known QT prolongation should be monitored. - Store at ambient temperature: keep below 25 °C, protect from moisture and retain in the original packaging.

Levocetirizine may interact with other medicines; awareness of the interaction level helps guide clinical decisions.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): may increase levocetirizine plasma concentrations. - Concurrent use of other sedating antihistamines: additive central nervous system depression.

Moderate Interactions (Monitor Closely): - Alcohol and other CNS depressants: may enhance drowsiness. - QT‑prolonging agents (e.g., certain antiarrhythmics, fluoroquinolones): monitor cardiac rhythm. - Grapefruit juice: can modestly affect metabolism. - Antihypertensive drugs: may potentiate hypotensive effects in susceptible individuals.
