Zirin is a brand name for cetirizine, an antihistamine used to relieve allergy symptoms. It is commonly prescribed for various allergic conditions, including hay fever and chronic urticaria (hives).
Key Features
- Active Ingredient: Each capsule contains 10 mg of cetirizine hydrochloride.
- Formulation: Available in capsule form, making it easy to swallow.
Indications
Zirin is indicated for:
- Allergic Rhinitis: Relief from symptoms such as sneezing, runny or itchy nose, and itchy or watery eyes caused by pollen, dust mites, animal dander, and other allergens.
- Chronic Urticaria: Reduces itching and the number and size of hives.
- Other Allergic Reactions: Helps alleviate symptoms associated with allergic reactions.
Mechanism of Action
Cetirizine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. As a second-generation antihistamine, it is less likely to cause sedation compared to first-generation antihistamines.
