Cetrizine is an oral antihistamine that contains cetirizine hydrochloride, commonly used to relieve symptoms associated with allergies. The 30ml syrup formulation is particularly suitable for children and adults who prefer liquid medication.

- Allergic Conjunctivitis: Itching and redness in the eyes due to allergies.

Mechanism of Action
Cetirizine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. By inhibiting histamine receptors, it reduces symptoms such as sneezing, itching, and runny nose.
