What Antibiotics Are Best For Urinary Tract Infections

Which Antibiotic Will Work Best

Your doctor will take a urine sample to confirm that you have a UTI. Then the lab will grow the germs in a dish for a couple of days to find out which type of bacteria you have. 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:

• Trimethoprim/sulfamethoxazole

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?

Why Antibiotics Sometimes Dont Work

Most UTIs arent serious. But if left untreated, the infection can spread up to the kidneys and bloodstream and become life threatening. Kidney infections can lead to kidney damage and kidney scarring.

Symptoms of a UTI usually improve within 2 to 3 days after starting antibiotic therapy. Many doctors prescribe an antibiotic for at least 3 days.

While this type of medication is the standard treatment, researchers are noticing that antibiotic-resistant bacteria are reducing the effectiveness of some antibiotics in treating UTIs.

Some UTIs dont clear up after antibiotic therapy. When an antibiotic medication doesnt stop the bacteria from causing an infection, the bacteria continue to multiply.

The overuse or misuse of antibiotics is often the reason for antibiotic resistance. This can happen when the same antibiotic is prescribed over and over again for recurrent UTIs. Because of this risk, experts have been looking for ways to treat UTIs without antibiotics.

Some research has shown that UTIs can be treated without traditional antibiotics by targeting E. colis surface component for adhesion, FimH.

Typically, the urinary tract flushes away bacteria when you urinate. But according to researchers, FimH can cause E. coli to firmly attach to the cells in the urinary tract. And because of this tight grip, its hard for the body to naturally flush the bacteria from the urinary tract.

What Are The Causes Of Urinary Tract Infections In Dogs

In most cases, UTIs are caused by bacteria, most commonly Escherichia Coli. They migrate from the outside through the urethra to the bladder. When the bladder is inflamed, this is called cystitis.

A dog that does not urinate often is more prone to bacterial urinary tract infections, as these bacteria have more time to migrate and develop in the bladder. Thats why its important to provide frequent wee breaks for your dog.

Some dogs are also more susceptible to UTIs and can have them repeatedly.

Diet plays an important role as well, as it influences the pH of the urine. A slightly acidic pH is preferred, as the bacteria develop more easily in an alkaline pH environment. See below how to help achieve this optimal pH level.

• Your dog has a harder time holding his bladder.
• They need to wee in small amounts, and more often.
• They start to have accidents in the house.
• Noticeable dripping after they have finished urinating .
• The urine looks darker and smelly.

• Your pet seems in pain during urination, it seems forced.
• You notice blood in the urine.

Antiseptic Drug As Good As Antibiotics For Preventing Recurrent Urinary Tract Infections

And may also help tackle antibiotic resistance, say researchers

The antiseptic drug methenamine hippurate is as good as antibiotics for preventing recurrent urinary tract infections in women, finds a trial published by The BMJ today.

Its use as an alternative to antibiotics may also help tackle the global burden of antibiotic resistance, say the researchers.

Over half of women have at least one urinary tract infection in their lifetime, and recurrence occurs in about a quarter of women who have one episode.

Current guidelines recommend daily low dose antibiotics as the standard preventive treatment for recurrent UTI. But such long term use of antibiotics has been linked to antibiotic resistance, so research into non-antibiotic alternatives is urgently needed.

Methenamine hippurate is a drug that sterilises urine, stopping the growth of certain bacteria. Previous studies have shown that it could be effective in preventing UTIs, but the evidence is inconclusive and further randomised trials are needed.

So a team of UK researchers, led by clinicians and scientists from Newcastle-upon-Tyne, set out to test if methenamine hippurate is an effective alternative to standard antibiotic treatment for preventing recurrent UTI in women.

Their findings are based on 240 women with recurrent urinary tract infections requiring prophylactic treatment. On average before trial entry these women experienced over six UTI episodes per year.
