Generic Levocetirizine Information

Introduction

Levocetirizine is a second‑generation antihistamine used principally to relieve symptoms of allergic rhinitis and chronic idiopathic urticaria. In the United Kingdom it is prescribed when rapid relief of sneezing, itchy watery eyes, nasal congestion, or hives is required, and when a non‑sedating option is preferred. The active compound, levocetirizine, belongs to the Allergy medication group and is the pharmacologically active enantiomer of cetirizine. The drug is available as a generic product and under well‑known brand names such as Xyzal®. It is manufactured by several licensed pharmaceutical companies, including UCB Pharma and Teva UK, and is listed on the UK Medicines and Healthcare products Regulatory Agency (MHRA) register.

What is Levocetirizine?

Levocetirizine is the generic version of Xyzal®, containing the same active compound levocetirizine dihydrochloride. It is an oral antihistamine that selectively blocks peripheral H₁ receptors, preventing histamine‑mediated allergic responses. The molecule is the (R)-enantiomer of cetirizine, which gives it a higher affinity for the H₁ receptor and a reduced potential for central nervous system penetration, thereby limiting drowsiness. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, offering the same therapeutic benefit as the branded product at a lower price.

How Levocetirine Works

Histamine released from mast cells during an allergic reaction binds to H₁ receptors on blood vessels, nerves, and mucosal surfaces, causing vasodilation, increased vascular permeability, and sensory nerve stimulation. Levocetirizine competitively antagonises these H₁ receptors, inhibiting the downstream cascade that leads to itching, swelling, and secretion of mucus. Because it is highly selective for peripheral receptors, the compound does not readily cross the blood‑brain barrier, which accounts for its low sedative profile compared with first‑generation antihistamines. Onset of action is typically observed within 1 hour after oral administration, with a therapeutic effect lasting up to 24 hours, allowing once‑daily dosing. Levocetirizine is eliminated primarily by the kidneys; its plasma half‑life in healthy adults is about 8–9 hours, and renal clearance is proportional to glomerular filtration rate.

Conditions Treated with Levocetirine

• Seasonal allergic rhinitis (hay fever). Approximately 12 % of the UK adult population experiences seasonal symptoms; antihistamines reduce sneezing, rhinorrhoea, and nasal itching.
• Perennial allergic rhinitis. Persistent indoor allergens (dust mites, animal dander) provoke similar histamine‑driven symptoms; levocetirizine provides consistent daily control.
• Chronic idiopathic urticaria (hives). The condition affects about 1 % of adults in the UK; levocetirizine mitigates wheal formation and pruritus by blocking histamine release on the skin.
• Allergic conjunctivitis. By stabilising ocular H₁ receptors, levocetirizine alleviates redness, itching, and tearing.

The drug is not indicated for asthma, anaphylaxis, or other non‑histamine mediated conditions, although it be used adjunctively when concomitant allergic rhinitis is present.

Who is Levocetirine For?

Levocetirizine is appropriate for adults (≥ 18 years) who require reliable, non‑sedating allergy relief. It is especially useful for:

• Individuals with work or study schedules where daytime drowsiness would impair performance.
• Patients with recurrent chronic urticaria unresponsive to low‑dose antihistamines.
• Those who have experienced insufficient control with first‑generation antihistamines or who report intolerable side‑effects such as dry mouth or significant sedation.

Contra‑indications include hypersensitivity to levocetirizine or any excipients, severe renal impairment (creatinine clearance < 30 mL/min), and known prolonged QT interval without specialist supervision. Pregnant or breastfeeding women should only use levocetirizine when the potential benefit outweighs the theoretical risk, as safety data are limited.

Risks, Side Effects, and Interactions

Common

• Headache – mild to moderate, often resolves without intervention.
• Dry mouth – may be mitigated by sipping water or chewing sugar‑free gum.
• Fatigue or mild drowsiness – occurs in < 5 % of users; less frequent than with first‑generation agents.

Rare

• Palpitations or tachycardia – reported in isolated case reports, usually in patients with pre‑existing cardiac conditions.
• Elevated liver enzymes – occasional transient rise; monitor if pre‑existing hepatic disease.

Serious

• Anaphylactic reactions – extremely rare; immediate emergency medical care required.
• Severe cutaneous adverse reactions (e.g., Stevens‑Johnson syndrome) – urgent discontinuation and specialist assessment needed.

Clinically Relevant Drug Interactions

• CYP3A4 inhibitors (ketoconazole, erythromycin) – may increase levocetirizine plasma concentrations; dose adjustment rarely required but monitor for excess sedation.
• Alcohol – additive CNS depressant effect can increase drowsiness; patients should limit intake.
• Other antihistamines – concurrent use may heighten anticholinergic burden without added benefit; generally discouraged.
• Renal‑impairing agents (e.g., NSAIDs in high doses) – may reduce clearance; consider dose reduction in patients with moderate renal dysfunction.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose: 5 mg (one tablet) taken orally once daily, with or without food. The tablet may be swallowed whole; do not crush or chew.
• Missed dose: If the dose is remembered within 12 hours, take it immediately. If more than 12 hours have passed, skip the missed dose and resume the regular dosing schedule. Do not double‑dose.
• Overdose: Symptoms may include excessive sedation, tachycardia, or gastrointestinal upset. In the event of suspected overdose, seek urgent medical advice; treatment is mainly supportive, as levocetirizine has no specific antidote.
• Food and alcohol: Food does not significantly affect absorption, so the medication can be taken with meals. Excessive alcohol should be avoided due to potential additive sedation.
• Comorbidities: Patients with renal impairment (eGFR < 30 mL/min) should use a reduced dose of 2.5 mg once daily; dose adjustments are not required for mild hepatic disease.

FAQ

• **Is levocetirine available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is marketed as Xyzal®, while generic levocetirine tablets contain the same active ingredient and are typically less expensive.

• **Does levocetirine require refrigeration or special storage conditions?
  No. The tablets should be stored at room temperature (15‑30 °C), protected from moisture, light, and extreme heat.

• **What do levocetirine tablets look like, and are there any identifiable markings?
  Generic levocetirine tablets are usually white, round, and debossed with “5 mg” or the manufacturer's logo. Brand‑name Xyzal® tablets are also white but may have a different imprint pattern.

• **Can I travel internationally with levocetirine, and are there any customs restrictions?
  Levocetirine is classified as a prescription‑only medicine in most jurisdictions, but a personal supply for self‑use (up to a three‑month quantity) is generally permitted. Carry the original packaging and a copy of the prescription or a pharmacist’s statement to avoid customs delays.

• **Are there any known differences in formulation between EU and US levocetirine products?
  The active ingredient and dosage are identical, but excipients such as lactose, microcrystalline cellulose, or magnesium stearate may vary. Patients with specific excipient allergies should check the product’s ingredient list before use.

• **What clinical trials established levocetirine’s efficacy for chronic urticaria?
  Two pivotal double‑blind, placebo‑controlled Phase III studies (e.g., the ASTERION and SUNDIAL trials) demonstrated that levocetirine 5 mg once daily significantly reduces hive count and itch severity compared with placebo, with a favourable safety profile.

• **Does levocetirine affect drug testing for employment or sports?
  Levocetirine is not listed on standard occupational drug‑screening panels and is permitted by most sport anti‑doping agencies, as it does not possess psychoactive properties.

• **Can levocetirine be taken with other over‑the‑counter (OTC) allergy remedies?
  Concurrent use of multiple antihistamines is discouraged due to limited additional benefit and increased risk of adverse effects. However, nasal saline irrigation or intranasal corticosteroids can be safely combined with levocetirine for additive symptom control.

• **What should I do if I experience persistent drowsiness despite levocetirine’s low‑sedation claim?
  Although rare, some individuals are more sensitive to antihistamines. If drowsiness interferes with daily activities, discuss dose timing (e.g., evening administration) or alternative therapies with a pharmacist or healthcare professional.

• **Is levocetirine safe for patients with a history of cardiac arrhythmia?
  Levocetirine has a minimal effect on QT interval; however, patients with known prolonged QT or receiving other QT‑prolonging drugs should have cardiac monitoring and may require a dose adjustment or alternative therapy.

• **Can levocetirine be used in patients with severe liver disease?
  Hepatic metabolism plays a minor role in levocetirine clearance, so mild to moderate liver disease does not typically require dose modification. Severe hepatic impairment has not been extensively studied, and specialist guidance is advised.
