Therapeutic prophylactic and diagnostic injections

Therapeutic injections are administered to relieve symptoms or treat conditions, such as corticosteroids for inflammation or anesthetics for pain relief. Prophylactic injections are given to prevent diseases, like vaccines that protect against infections. Diagnostic injections, on the other hand, are used to aid in the diagnosis of medical conditions, such as contrast agents in imaging studies or local anesthetics to identify pain sources. Each type serves a distinct purpose in patient care and management.
