Summary
Bilastine is used to treat allergic rhinitis, which is inflammation of the nasal passages due to allergies, and urticaria, which is a skin rash with itchy welts. It helps reduce symptoms like sneezing, itching, and runny nose.
Bilastine works by blocking histamine receptors, which are parts of cells that react to histamine, a chemical causing allergy symptoms like itching and sneezing. By blocking these receptors, Bilastine prevents these symptoms.
The usual dose of Bilastine for adults is 20 mg once daily. It should be taken orally on an empty stomach, either one hour before or two hours after a meal.
Common side effects of Bilastine include headache and drowsiness, which means feeling sleepy. These effects are generally mild and affect a small percentage of people.
Bilastine may cause drowsiness, so avoid driving until you know how it affects you. It should be used with caution in people with severe kidney problems. Do not take Bilastine if you are allergic to it.
