Acute bacterial prostatitis is treated with antibiotics-and steps can be taken to reduce discomfort until symptoms go away. You can make sure the person takes a stool softener to relieve painful bowel movements. Offer plenty of fluids - anywhere from 64 to 128 ounces each - day to increase urination and continue to cleanse the bladder from bacteria. Encourage taking warm baths to help relieve back pain. And make sure the person completes the full course of antibiotics to avoid a recurrence.
