Bladder infection - adults; UTI - adults; Cystitis - bacterial - adults; Pyelonephritis - adults; Kidney infection - adults
Your doctor must first decide whether you have a mild or simple bladder or kidney infection, or whether your infection is more serious.
MILD BLADDER AND KIDNEY INFECTIONS
Antibiotics taken by mouth are usually recommended because there is a risk that the infection can spread to the kidneys.
Commonly used antibiotics include trimethoprim-sulfamethoxazole, amoxicillin, Augmentin, doxycycline, and fluoroquinolones. Your doctor will also want to know whether you could be pregnant.
Your doctor may also recommend drugs to relieve the burning pain and urgent need to urinate. Phenazopyridine hydrochloride (Pyridium) is the most common of this type of drug. You will still need to take antibiotics.
Everyone with a bladder or kidney infection should drink plenty of fluids.
Some women have repeat or recurrent bladder infections. Your doctor may suggest several different ways of treating these.

MORE SEVERE KIDNEY INFECTIONS
If you are very sick and cannot take medicines by mouth or drink enough fluids, you may be admitted to the hospital. You may also be admitted to the hospital if you:
At the hospital, you will receive fluids and antibiotics through a vein.
Some people have urinary tract infections that keep coming back or that do not go away with treatment. Such infections are called chronic UTIs. If you have a chronic UTI, you may need antibiotics for many months, or stronger antibiotics may be prescribed.
If a structural (anatomical) problem is causing the infection, surgery may be recommended.
A urinary tract infection is uncomfortable, but treatment is usually successful. Symptoms of a bladder infection usually disappear within 24 - 48 hours after treatment begins. If you have a kidney infection, it may take 1 week or longer for your symptoms to go away.
Contact your health care provider if you have symptoms of a UTI. Call right away if the following symptoms develop:
These may be signs of a possible kidney infection.
Also call if you have already been diagnosed with a UTI and the symptoms come back shortly after treatment with antibiotics.
