Mebhydrolin is primarily used as an antihistamine, effectively managing symptoms associated with allergic reactions. It is commonly prescribed to alleviate conditions such as hay fever, allergic rhinitis, and skin allergies like urticaria. By blocking histamine receptors, it reduces itching, sneezing, and runny nose, providing relief to patients. Additionally, it is sometimes used in the treatment of mild anxiety and as a sedative due to its calming effects. Its application in dermatology includes managing eczema and other allergic skin disorders. Mebhydrolin is often available in oral tablet or syrup form, making it convenient for patient use. Always consult a healthcare professional for proper dosage and suitability.
