The information provided here is meant to give you a general idea about each of the medications listed below. Only the most general side effects are included, so ask your doctor if you need to take any special precautions. Only use each of these medications as recommended by your doctor, or according to the instructions provided. If you have further questions about usage or side effects, contact your doctor.
You may be prescribed antibiotics for 3 or more days. A 3-day course has been shown to be helpful for both younger and older women with
urinary tract infections
(UTIs), rather than taking the medication for up to 10 days or more. You should take the full course of medication, even if you begin to feel better before all the medication is gone.
In some cases, severe UTIs are treated with IV or intramuscular antibiotics. Researchers, though, have found that oral antibiotics appear to be as effective in treating UTIs as those given as injections.
If you are suspected of having a more serious infection, such as a
kidney infection, you may need hospitalization, IV antibiotics, and fluids.
