Cetirizine 10 mg is a widely used antihistamine in Australia, popular for its effectiveness in relieving allergy symptoms. Whether you suffer from hay fever, perennial allergic rhinitis, or chronic hives, cetirizine offers fast and lasting relief. This blog post covers everything Australians should know about cetirizine 10 mg, including its uses, dosage, precautions, and availability.
What is Cetirizine 10 mg?
Cetirizine hydrochloride 10 mg is a second-generation antihistamine that works by blocking histamine H1 receptors in the body. Histamine is a chemical released during allergic reactions that causes symptoms such as sneezing, itching, watery eyes, and runny nose. By preventing histamine from binding to its receptors, cetirizine helps reduce these allergy symptoms effectively.
What is Cetirizine 10 mg Used For?
In Australia, cetirizine 10 mg is primarily used to treat:
- Seasonal Allergic Rhinitis (Hay Fever): Provides relief from sneezing, nasal congestion, itchy nose, and watery eyes caused by pollen and other seasonal allergens.
- Perennial Allergic Rhinitis: Manages year-round allergy symptoms triggered by indoor allergens like dust mites, pet dander, and mould.
- Chronic Idiopathic Urticaria (Hives): Helps reduce itching, redness, and swelling associated with chronic hives in adults and children over 12 years.
Recommended Dosage in Australia
- Adults and children aged 12 years and over: The usual dose is 1 tablet (10 mg) once daily.
- Children aged 6 to 12 years: Typically, a half tablet (5 mg) twice daily is recommended.
- Children under 6 years: Cetirizine tablets are generally not recommended; liquid formulations may be used under medical advice.
Tablets should be swallowed whole with water and can be taken with or without food. If cetirizine causes drowsiness, it is advisable to take it in the evening.
