Chlorohistol tablets are a trusted antihistamine medication designed to provide effective relief from allergy symptoms. Each tablet contains the active ingredient chlorpheniramine, a potent antihistamine that works by blocking the action of histamine in the body. Histamine is a natural substance that the body releases during allergic reactions, leading to symptoms like sneezing, itching, watery eyes, and runny nose. By inhibiting histamine's effects, Chlorohistol helps alleviate these symptoms, providing fast and long-lasting relief. The tablets are easy to swallow and are suitable for adults and children over 12 years old.
