How It Works

These medicines kill the bacteria that commonly cause urinary tract infections (UTIs).

Why It Is Used

Antibiotics treat a UTI. And they prevent complications of infection such as kidney damage.
Antibiotics also prevent UTIs. The doctor might prescribe preventive antibiotic therapy for:
  • Women who have recurrent UTIs (at least two UTIs in 6 months or three UTIs in 1 year).
  • Pregnant women who had recurrent UTIs before getting pregnantor during pregnancy.
  • People who have spinal cord injuries or other nervous systemconditions that affect urination.
  • People who have had a kidney transplant.
  • People who are going to have surgery involving the urinary tract.

How Well It Works

Antibiotics are effective for most UTIs. You should start to feel better within 1 to 2 days after starting antibiotics. If your symptoms get worse or you don't feel better by the third day, call your doctor.
It is important to take all of the antibiotics your doctor has prescribed. Most people begin to feel better soon after they begin the medicine. But if you stop taking the medicine as soon as you feel better, the infection may return.
When taken as preventive therapy, antibiotics also reduce the number of recurrent UTIs. But studies show that this kind of treatment is short-acting. When you stop taking an antibiotic, you are likely to get another UTI.

Acute diarrhea in children

Diarrhea refers to the passage of loose or watery stools or an increased frequency of stools for the child and occurs at some point in the life of nearly every child. Diarrhea is not a disease but is a symptom of a number of illnesses.  Although diarrhea is common and rarely serious, it is important to understand when to seek help.  Diarrhea can lead to dehydration, which alters the child's natural balance of water, and to electrolyte (sodium, potassium, chloride) imbalance.  It can be serious if not treated promptly. DIARRHEA CAUSES The most common cause of acute diarrhea is a viral infection. Other causes include bacterial infections, side effects of antibiotics, and infections not related to the gastrointestinal (GI) system. In addition, there are many less common causes of diarrhea.
