I was recently told I have a uti. I'm taking 2 bactrim for 10 days then 1 a day for 2 months. Nurse didn't explain why I have to take it for so long, just kept saying it's because I have a uti.
Here is the usual adult dose for a UTI: 1 BACTRIM DS (double strength) tablet or 2 BACTRIM tablets every 12 hours for 10 to 14 days. An identical daily dosage is used for 5 days in the treatment of shigellosis.
Bactrim is used to treat ear infections, urinary tract infections, bronchitis, traveler's diarrhea, shigellosis, and Pneumocystis jiroveci pneumonia.
Used as a prophylaxis in adults:
The recommended dosage for prophylaxis in adults is 1 BACTRIM DS (double strength) tablet daily.
My conclusion is that you are being treated (1) for a UTI and (2) prophylactically for one of the problems listed above that you are at risk for. Think about where you live and what you might be exposed to and you may find the reason you are on a preventive dose of antibiotic.
Shigellosis is an infection of the colon (large intestine) caused by Shigella bacteria. Shigellosis is also called bacillary dysentery because it can cause severe diarrhea. However, the infection often causes only mild symptoms.
Shigella can be found in water polluted with infected sewage. Bacteria commonly enter the body through a contaminated drinking supply. Shigella bacteria also can be found on food that has been rinsed with unclean water, grown in fields contaminated with sewage, or touched by flies that have touched feces. Shigella bacteria can reach the mouth on dirty fingers that have touched items soiled with feces, including dirty diapers, toilets and bathroom fixtures.
Outbreaks of shigellosis are most common in areas where sanitation is poor, and in places where people live under confined or crowded conditions. Shigella also can be passed from person to person during anal-oral sex.
