A combination of medications are used to lessen the spasms in the sphincter and pelvic muscles, and to calm the inflammation in the prostate. Alpha-blockers such as terazosin can be used for spasms. Sometimes a short course of a muscle relaxant like diazepam is used to help break the spasm. Anti-inflammatory agents such as ibuprofen can address the inflammation. Warm baths once or twice a day may also help.
Alpha-blockers can cause nasal congestion and headache. Diazepam and other muscle relaxants can cause drowsiness.
Non-bacterial prostatitis usually cannot be cured, but it can be managed. It helps a lot for the man to know that this is not a dangerous condition.
Once symptoms are gone there is no need for further monitoring. The man should contact a healthcare provider if symptoms persist or return.
