Used primarily as an antihistamine with antiemetic properties, it is effective in preventing and treating nausea, vomiting, and dizziness associated with motion sickness. It also helps manage symptoms of vertigo due to inner ear disorders. Due to its sedative effect, it may be used to relieve anxiety or tension in certain clinical settings. Its long duration of action allows for once-daily dosing, making it convenient for prophylactic use during travel or in chronic vestibular conditions.
