Dibucaine is widely used as a local anesthetic to relieve pain and discomfort associated with minor surgical procedures, dental work, and skin irritations. It works by blocking nerve signals in the affected area, providing temporary numbness. In medical settings, it is often applied topically in the form of creams, ointments, or gels to treat conditions like hemorrhoids, anal fissures, and minor burns. Additionally, dibucaine is utilized in some over-the-counter products to alleviate itching and irritation caused by insect bites, rashes, or minor skin injuries. Its effectiveness in reducing pain and inflammation makes it a valuable component in various therapeutic formulations.
