Primarily used as an antihistamine, it effectively manages allergic conditions such as rhinitis, urticaria, and other skin-related allergic reactions. It works by blocking histamine receptors, reducing symptoms like itching, sneezing, and runny nose. Additionally, it is sometimes prescribed for its anti-anxiety and sedative properties, aiding in mild anxiety disorders or sleep disturbances. Its anti-inflammatory effects also make it useful in treating certain inflammatory skin conditions. Always administered under medical supervision to ensure proper dosage and minimize potential side effects.
