Over the counter pain medication will suffice (Tylenol). Ask your Healthcare provider or better talk to your Urologist who did the procedure. They will prescribe you meds. In case you needed. Thank you

Pain following a prostate biopsy can be considered to be inflammatory. My recommendation would be to use a nonsteroidal anti-inflammatory drug such as ibuprofen (assuming you don't have any significant risks for heart attack or stroke or have uncontrolled high blood pressure). Might need to use it for about three days and things should improve rather quickly. Good luck!
