Types of Antibiotics for a Urinary Tract Infection

A urinary tract infection (UTI) is a bacterial infection in the urinary system, which includes the bladder, urethra, ureters and kidneys. UTI symptoms usually include a frequent urge to urinate, pressure in the lower abdomen and a stinging sensation while urinating. Urinary tract infections are typically treated with antibiotics.
  1. Penicillin

    • Penicillin medications, particularly Amoxicillin, are commonly prescribed to UTI patients. Penicillin kills the bacteria by interfering with the cell walls.

    Cephalosporin

    • Cephalosporin is another antibiotic that interferes with bacterial cell walls. This antibiotic effectively kills various bacteria growing in the urinary tract system.

    Trimethoprim-Sulfamethoxazole

    • Trimethoprim-sulfamethoxazole (TMP-SMX) is a sulfa antibiotic that is increasingly being used to treat UTIs. This antibiotic has a higher risk of side affects, and can interfere with the effectiveness of oral contraceptives.

    Quinolones

    • Quinolones, also referred to as fluoroquinolones, stop the bacteria from reproducing by interfering with their genes. These medications tend to be more expensive than other types of antibiotics.

    Tetracyclines

    • Tetracyclines cure UTIs by inhibiting bacterial growth. Side effects often include a sensitivity to sunlight and tooth discoloration.

    Nitrofurantoin

    • Nitrofurantoin is a fairly inexpensive antibiotic prescribed especially for UTIs. While this medication typically works for bladder infections, it isn't effective for kidney infections.
