Indications & Clinical Uses

Levocetirizine is an antihistamine that acts on histamine‑mediated allergic conditions.

  • Allergic rhinitis: reduces sneezing, nasal itching, congestion and rhinorrhea.
  • Chronic idiopathic urticaria: alleviates hives and associated itching.
  • Histamine‑mediated allergic symptoms (e.g., conjunctivitis): provides symptomatic relief of itching and watery eyes.

How It Works

  • Levocetirizine selectively blocks peripheral H1‑histamine receptors, preventing histamine from binding and activating the cascade that leads to vasodilation, increased vascular permeability, and sensory nerve stimulation. By inhibiting this pathway, the drug diminishes the classic signs of an allergic response without crossing the blood‑brain barrier in significant amounts.

Side Effects

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

Common Side Effects

  • Drowsiness: mild to moderate sedation, especially at treatment initiation.
  • Headache: transient, often resolves with continued use.
  • Dry mouth: reduced salivation causing mild discomfort.
  • Fatigue: feeling of reduced energy.
  • Nausea: occasional stomach upset.
  • Altered taste: temporary metallic or bitter sensation.

Serious or Rare Side Effects

  • Angioedema: swelling of face, lips or throat requiring urgent care.
  • Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
  • Anaphylaxis: rare systemic allergic reaction.
  • Cardiac arrhythmia: abnormal heart rhythm in susceptible individuals.
  • Hepatic dysfunction: elevated liver enzymes.
  • Blood dyscrasias: rare cases of neutropenia or thrombocytopenia.

Precautions & Warnings

Before using Levocetirizina Activase, consider the following safety measures.

  • Pregnancy: consult a healthcare professional; risk‑benefit assessment is required.
  • Breastfeeding: evaluate potential exposure to the infant.
  • Renal impairment: dose adjustment may be necessary in reduced kidney function.
  • Elderly patients: monitor for increased sedation or confusion.
  • Alcohol and CNS depressants: avoid or limit use as additive drowsiness may occur.
  • Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Levocetirizina Activase can interact with other medicines; awareness helps prevent adverse outcomes.

Major Interactions (Avoid)

  • Ketoconazole: may raise levocetirizine plasma concentrations.
  • Erythromycin: can increase systemic exposure.
  • Ritonavir: may significantly elevate drug levels.

Moderate Interactions (Monitor Closely)

  • Alcohol: additive sedative effect, monitor drowsiness.
  • Other CNS depressants (e.g., benzodiazepines): watch for enhanced sedation.
  • Theophylline: may increase its clearance, reducing therapeutic effect.

Frequently Asked Questions

Levocetirizina Activase contains levocetirizine, an antihistamine indicated for the relief of symptoms associated with allergic rhinitis—including seasonal and perennial forms—as well as chronic idiopathic urticaria, where it helps reduce hives and itching.

Levocetirizine acts as a selective peripheral H1‑receptor antagonist. By blocking histamine from binding to these receptors, it prevents the cascade that leads to vasodilation, increased vascular permeability, and nerve stimulation, thereby reducing typical allergic signs such as sneezing, itching, and swelling.

The appropriate dose is determined by the prescribing healthcare professional based on the patient’s age, weight, renal function and the specific condition being treated. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety in pregnancy and lactation has not been definitively established. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using the product.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Levocetirizine is the active enantiomer of cetirizine, offering similar efficacy with a potentially lower incidence of sedation. Compared with first‑generation antihistamines, it provides effective symptom control while crossing the blood‑brain barrier to a lesser extent, resulting in fewer central nervous system effects.

Store the product at temperatures below 25 °C in its original packaging. Protect it from moisture, excessive heat and direct sunlight to maintain potency throughout its shelf life.

Levocetirizina Activase is taken orally, typically as a tablet swallowed with water. It may be taken with or without food, according to the prescriber’s guidance.

Serious but rare adverse events include angioedema, severe skin reactions such as Stevens‑Johnson syndrome, anaphylaxis, cardiac arrhythmias, hepatic dysfunction and hematologic abnormalities. Patients should seek immediate medical attention if they experience swelling of the face or throat, rash, or unexplained fatigue.

Individuals with known hypersensitivity to levocetirizine or any excipients in the formulation should avoid the product. Caution is also advised for patients with severe renal impairment, as dose adjustment may be required, and for those taking medications that significantly increase levocetirizine levels.
