Carebastine is primarily utilized as an antihistamine to alleviate symptoms associated with allergic conditions. It is effective in reducing symptoms such as sneezing, runny nose, itching, and watery eyes caused by allergic rhinitis. Additionally, it is used to manage skin reactions like hives and itching in cases of chronic urticaria. Carebastine works by blocking the action of histamine, a substance in the body that triggers allergic symptoms, providing relief and improving the quality of life for individuals suffering from these conditions.
