Urinary Tract Infection

Medications used to treat urinary tract infections (UTIs).

What is a Urinary Tract Infection (UTI)?

The urinary system is the body's drainage system for removing wastes and extra water. It includes two kidneys, two ureters, a bladder, and a urethra. A urinary tract infection (UTI) occurs when bacteria enter the urinary system and cause an infection.

Symptoms of a UTI

You may have a UTI if you notice pain or burning when you urinate, fever, tiredness, or shakiness. Other symptoms include an urge to urinate often, pressure in your lower belly, urine that smells bad or looks cloudy or reddish, and pain in your back or side below the ribs.

Who is at Risk?

People of any age or sex can get UTIs, but about four times as many women get UTIs as men. You are also at higher risk if you have diabetes, need a tube to drain your bladder, or have a spinal cord injury.

Why is Treatment Important?

If left untreated, a UTI can lead to more serious health issues. It is important to see your doctor if you think you have a UTI.

How is a UTI Treated?

Your doctor can confirm a UTI with a urine test. Treatment typically involves antibiotics. Lifestyle changes may also help manage symptoms.

When to See a Doctor

If you think you have a UTI, it is important to see your doctor for proper diagnosis and treatment.

Medications used to treat Urinary Tract Infection

Several classes of medication treat urinary tract infection. Which is right depends on your health — that is a decision for you and your provider. Compare prices and coupons on any of them:

Penicillins
Penicillins work by inhibiting the synthesis of bacterial cell walls, leading to cell lysis and death.
Cephalosporins
Cephalosporins disrupt the formation of the bacterial cell wall, similar to penicillins, making them effective against a wide range of bacteria.
Fluoroquinolones
Fluoroquinolones inhibit bacterial DNA gyrase and topoisomerase IV, enzymes critical for DNA replication and repair.
Aminoglycosides
Aminoglycosides work by binding to bacterial ribosomes, inhibiting protein synthesis and leading to cell death.
Sulfonamides
Sulfonamides inhibit bacterial growth by interfering with the synthesis of folic acid, which is necessary for DNA and RNA production.
