You have been diagnosed with bacterial prostatitis. This is an infection of the prostate gland.
If you have acute prostatitis, your symptoms started quickly. After you start treatment, you may still feel ill, with fever, chills, and flushing (skin redness). It may hurt a lot when you urinate for the first few days. The fever and pain should begin improving over the first 36 hours.
If you have chronic prostatitis, your symptoms are likely to begin slowly and be less severe. Symptoms will probably improve slowly over many weeks.
It is likely you will have antibiotics to take home. Follow the directions on the bottle carefully. Take the antibiotics at the same time every day.
For acute prostatitis, antibiotics are taken for 2 to 6 weeks. Chronic prostatitis may be treated with antibiotics for at least 2 to 6 weeks if an infection is found. Because the infection can come back, you may need to take medicine for up to 12 weeks.
Finish all the antibiotics, even if you start feeling better. It is harder for antibiotics to get into prostate tissue to treat the infection. Taking all of your antibiotics will reduce the chance of the condition returning.
Antibiotics may cause side effects. These include nausea or vomiting, diarrhea, and other symptoms. Report these to your health care provider. Do not just stop taking your pills.
Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, may help with pain or discomfort. Ask your provider if you can take these.
Warm baths may relieve some of your perineal (the area between the scrotum and anus) and lower back pain.
Avoid substances that irritate the bladder, such as alcohol, caffeinated beverages, citrus juices, and acidic or spicy foods.
Drink plenty of fluids, 64 or more ounces (2 or more liters) per day, if your provider says this is OK. This helps flush bacteria from the bladder. It can also help prevent constipation.
To reduce discomfort with bowel movements, you may also:
See your provider for an exam after you finish taking antibiotics to make sure that the infection is gone.
If you do not improve or you are having problems with your treatment, talk to your provider sooner.
