Cephalexin For Chronic Uti

If this is not your first UTI, know one thing: you may not be fighting single-celled free-floating bacteria in your bladder. Most likely, you are fighting bacterial biofilms.

Cephalexin stops the growth of the cell wall, which bacteria need to survive. However, bacteria eventually learn how to hide from the antibiotic attack, allowing them to become resistant to Cephalexin.

One method is for them to team up, cover themselves with a protective slime, and hide in the deeper layers of your bladder lining. This allows bacteria to wait until you stop taking antibiotics before renewing their activity.

This bacterial method of defense is called bacterial biofilms.

This is called a culture. Itâll tell your doctor what type of germs caused your infection. Theyâll likely prescribe one of the following antibiotics to treat it before the culture comes back:

Which medication and dose you get depends on whether your infection is complicated or uncomplicated.

âUncomplicatedâ means your urinary tract is normal. âComplicatedâ means you have a disease or problem with your urinary tract. You could have a narrowing of your ureters, which are the tubes that carry urine from your kidneys to your bladder, a narrowing in the urethra which transports urine from the bladder out of the body, or, you might have a blockage like a kidney stone or an enlarged prostate . It’s also possible you have a urinary fistula or a bladder diverticulum.

To treat a complicated infection, your doctor might prescribe a higher dose of antibiotics. If your UTI is severe or the infection is in your kidneys, you might need to be treated in a hospital or doctor’s office with high-dose antibiotics you get through an IV.

Your doctor will also consider these factors when choosing an antibiotic:

  • Are you over age 65?
  • Are you allergic to any antibiotics?
  • Have you had any side effects from antibiotics in the past?

In dogs and cats, if UTI occurs only once or twice yearly, each episode may be treated as an acute, uncomplicated UTI. If episodes occur more often, and predisposing causes of UTI cannot be identified or corrected, chronic low-dose therapy may be necessary. Low antimicrobial concentrations in the urine may interfere with fimbriae production by some pathogens and prevent their adhesion to the uroepithelium. In dogs, recurrent UTIs are due to a different strain or species of bacteria ~80% of the time therefore, antimicrobial culture and susceptibility is still indicated. Antimicrobial therapy should be started as previously described and when urine culture is negative, continued daily at the total daily dose. The antimicrobial should be administered last thing at night to ensure that the bladder contains urine with a high antimicrobial concentration for as long as possible.
