Both Histazine and Zyrtec are used to relieve allergy symptoms. They belong to the same class of medications and contain the same active ingredient. Understanding this fundamental similarity helps understand their uses and therapeutic expectations.
Histazine Tablets Ingredients
Histazine Tablets contain the active ingredient cetirizine. Cetirizine is a second-generation antihistamine. It works by blocking the action of histamine, a chemical released by the body in response to allergens that causes symptoms such as itching, sneezing, runny nose, and watery eyes.
Zyrtec Tablets Ingredients
Zyrtec Tablets also contain the active ingredient cetirizine, which has the same mechanism of action as described above. Therefore, the therapeutic effects of taking Zyrtec are very similar to those of taking Histazine in terms of relieving allergy symptoms.
