Procedure and Effectiveness
To get an injection of prednisone for a sinus infection, you need to meet an ear, nose, and throat specialist. He or she will first give you a numbing agent to help reduce pain. After that, the medication will be administered into the sinuses via the nostrils. This is an in-office and quick procedure.
Prednisone tends to work quickly and can last for a long time. Another injection is needed only when the symptoms recur, typically between 3 and 12 months after the first injection. [4]
