Overview
Sunward Sunizine 10mg Tablet contains Cetirizine 10mg, a second-generation, non-sedating (or low-sedating) antihistamine used to relieve symptoms of allergies. It helps relieve sneezing, runny or itchy nose, itchy and watery eyes, and itchy skin associated with conditions such as allergic rhinitis (hay fever), seasonal allergies, and hives (urticaria).
This tablet is available over the counter in Malaysia without a doctor’s prescription for adults and adolescents within the age range stated on the packaging. It is intended for the relief of typical allergy symptoms; if symptoms are severe, do not improve with regular use, or are accompanied by breathing difficulty or facial swelling, a doctor should be consulted promptly.
How it Works
Cetirizine works by blocking histamine H1 receptors throughout the body. Histamine is released during an allergic reaction and is responsible for triggering symptoms such as itching, sneezing, and a runny or blocked nose; by blocking its action at these receptor sites, Sunward Sunizine 10mg Tablet reduces these allergy symptoms, generally with a low tendency to cause the drowsiness associated with older, first-generation antihistamines.
Directions for Use
Swallow the tablet whole with a glass of water, with or without food, generally once daily. Sunward Sunizine 10mg Tablet can be taken at any convenient time but is often taken at the same time each day for consistent symptom control, especially during periods of ongoing allergen exposure such as haze or pollen season.
Dosage
For adults and adolescents, the usual dose is one 10mg tablet taken once daily, not to be exceeded within a 24-hour period. Those with reduced kidney function or elderly patients may require a lower dose as advised by a doctor or pharmacist. This tablet is not recommended for young children; a lower-strength syrup formulation is more appropriate for pediatric use.
Shelf Life
Sunward Sunizine 10mg Tablet typically has a shelf life of around 24 to 36 months from the date of manufacture when unopened and stored correctly; always check the expiry date printed on the blister strip or carton and do not use beyond this date.
