Allerzal 5mg Film Coated Tablet

Allerzal 5mg Film Coated Tablet contains levocetirizine 5mg, a second-generation, non-sedating antihistamine used to relieve the symptoms of allergic conditions such as allergic rhinitis (including hay fever) and chronic idiopathic urticaria (hives). It helps reduce sneezing, a runny or itchy nose, watery and itchy eyes, and skin itching or wheals, allowing people with allergies to go about their daily activities more comfortably.

Allerzal 5mg Film Coated Tablet is generally available as a non-prescription medicine, suitable for self-selected use in typical allergy symptoms. Customers who are pregnant, breastfeeding, have kidney problems, or are unsure whether it is suitable for them are encouraged to seek pharmacist or doctor advice, which is available through DoctorOnCall’s online consultation service.

Levocetirizine is the active R-enantiomer of cetirizine and works by selectively blocking peripheral H1 histamine receptors, preventing histamine from causing the typical allergic symptoms of itching, swelling, and mucus production, while causing less sedation than first-generation antihistamines because it crosses into the brain to a lesser extent.

Take Allerzal 5mg Film Coated Tablet once daily, with or without food, swallowing the tablet whole with a glass of water. It can be taken at any convenient time of day, but taking it at the same time each day helps maintain consistent symptom control.

The usual adult and adolescent (12 years and above) dose is one 5mg tablet once daily, and the dose should not be repeated within 24 hours. People with reduced kidney function may need a lower dose or less frequent dosing as advised by a pharmacist or doctor, so it is worth checking suitability if you have known kidney impairment.

Allerzal 5mg Film Coated Tablet is generally stable for up to 36 months from the date of manufacture when unopened and stored correctly. Check the expiry date on the blister strip or carton before use.

Store Allerzal 5mg Film Coated Tablet below 30°C in a dry place away from direct sunlight and moisture, keeping it in its original packaging until needed. Keep out of the sight and reach of children.

• Known hypersensitivity to levocetirizine, cetirizine, or any of the tablet’s other ingredients
• Severe renal impairment (end-stage renal disease)
• Children under 6 years of age unless advised by a doctor
• Hereditary galactose intolerance or other rare conditions affecting sugar metabolism, due to the lactose content

• Alcohol and other sedating medicines may increase drowsiness when taken together, although the sedative effect of levocetirizine itself is generally mild
• Theophylline may slightly reduce the clearance of levocetirizine from the body
• Other centrally acting sedatives may add to any mild drowsiness that occurs
• Ritonavir may increase the amount of levocetirizine in the body, so caution is advised if combined

• Take Allerzal 5mg Film Coated Tablet at the same time each day for consistent allergy control
• Assess how the tablet affects you before driving or operating machinery, even though sedation is uncommon
• Do not exceed one tablet in 24 hours
• Consult a pharmacist if you have kidney problems before use
• Seek medical advice if allergy symptoms do not improve after a few days of regular use

As a non-sedating, once-daily antihistamine, Allerzal 5mg Film Coated Tablet is often preferred by people who need reliable allergy control without significant drowsiness during work or study, though individual responses can vary and a small number of people may still feel mild sleepiness.
