Xyzal 5mg Tablets are a highly effective, prescription-strength, non-drowsy antihistamine used to relieve symptoms associated with seasonal allergies, year-round indoor allergies, and chronic hives. It is known for acting quickly and providing long-lasting, 24-hour symptom control.
Active Ingredient & Mechanism
-
Levocetirizine Dihydrochloride (5mg): This is a second-generation antihistamine. It works by selectively blocking histamine H1 receptors in the body, preventing the swelling, itching, and mucus production triggered by allergens.
-
Key Advantage: Levocetirizine is the active form of cetirizine (the compound found in Zyrtec). It is more potent, meaning a smaller dose (5mg) is required to achieve the same or better relief than standard cetirizine (10mg), often with less drowsiness.
Approved Uses
Xyzal is primarily indicated for:
-
Allergic Rhinitis: Stops sneezing, runny or itchy nose, and watery, red, or burning eyes.
-
Chronic Idiopathic Urticaria: Relieves severe skin itching and reduces the appearance of hives (nettle rash).
Standard Dosage Guidelines
Tablets should be swallowed whole with water, with or without food. It is frequently recommended to take this medication in the evening, as some individuals may still experience mild relaxation or sleepiness.
-
Adults and children over 12 years: 1 tablet (5mg) once daily.
-
Children 6 to 12 years: Half a tablet (2.5mg) once daily.
-
Note: For children under 6 years, a liquid syrup formulation is preferred over tablets.
Side Effects & Precautions
-
Mild Drowsiness: Although classified as a non-drowsy antihistamine, it can cause mild fatigue or sleepiness in a small percentage of users. Avoid operating heavy machinery until you know how it affects you.
-
Dry Mouth & Sore Throat: Drinking plenty of water can help mitigate mild dryness.
-
Kidney Impairment: Since levocetirizine is cleared heavily by the kidneys, patients with renal disease require reduced doses or should avoid it entirely under medical supervision.
