How Effective is Amoxicillin for a Urinary Tract Infection

What happens when UTIs are left untreated? Contrary to popular belief, your immune system is often able to clear a UTI on its own. Studies have found that 25-42% of women are able to recover from an uncomplicated UTI without antibiotics.

But that means a majority of UTIs do not go away on their own. If left untreated, they can lead to continued discomfort and other more serious health issues, such as kidney damage or a severe infection. Therefore, treatment is recommended.

“Physicians tailor care plans to each patient, and there is no sole treatment for everyone,” says Stanford physician Kim Chiang, MD. During your visit, feel free to ask in-depth questions, particularly if a non-recommended antibiotic is prescribed.

This is the fifth post in the series Understanding UTIs. The goal of this seven-part series is to provide easy-to-understand, scientifically grounded information about UTIs. Patients referenced are composites, compiled from actual patient experiences.Data on medications used for UTIs were extracted from the National Disease and Therapeutic Index, a nationally representative physician survey produced by IQVIA.

Treatments For A Urinary Tract Infection

The type of treatment you are prescribed and the length of time you need to take medicine depends on your health history and the type of bacteria found in your urine.

Medications

Doctors commonly prescribe antibiotics for urinary tract infections. Amoxicillin is a type of antibiotic medicine that stops the growth of bacteria in your urine.

Amoxicillin comes as a capsule, tablet, or liquid to be taken by mouth. The medicine is taken two or three times a day with or without food. If you have a UTI and are prescribed an antibiotic like amoxicillin, you should start feeling better within a few days. It is important to remember that even though your symptoms may start to subside within a few days, you should continue to take your medicine as prescribed by your doctor. The treatment length depends on your unique circumstances.

Home care

A healthy lifestyle that includes methods like regular bathing and good hygiene may help you control and prevent urinary tract infections. These techniques include:

  • Choosing NOT to use or feminine hygiene products containing perfumes
  • Avoiding bath oils
  • Taking showers instead of baths
  • Keeping the genital area clean
  • Drinking water after sexual activity
  • Wiping front to back after using the bathroom
  • Wearing clean cotton-cloth underwear and changing underwear daily
  • Avoiding excessive amounts of alcohol and caffeine

What Can I Do To Prevent A Uti From Occurring In The Future

Your veterinarian will let you know if there is anything that can be done to prevent your dogs UTI from recurring. Often, a diet change may be recommended. They may also recommend some medications or supplements that can help to change the pH of the urine, making it harder for an infection to take hold. It is best to discuss UTI prevention with your veterinarian in order to put into place strategies that have been shown to be effective.

When To See A Doctor

If you have signs of a UTI, talk to your doctor or healthcare provider.

While not all UTIs require antibiotics, most of them do.

Leaving a UTI untreated can result in serious complications such as a kidney infection.

If a healthcare provider prescribes amoxicillin-clavulanate potassium for a UTI and you experience any serious side effects, contact them.

But if you think youre having an allergic reaction, head to the emergency room or call 911.

Also contact your doctor if your UTI doesnt appear to clear after finishing the full course of antibiotics or if symptoms worsen.

Do I Really Need To Take Antibiotics For A Uti

In most cases, it makes sense to start antibiotics if you know you have a bacterial UTI since this is the only way to treat it.

While it is possible for a UTI to go away on its own, this doesnt always happen. Plus, youll still have to deal with uncomfortable UTI symptoms like pain during urination while waiting to see if the UTI will go away. And if it doesnt, the infection can travel up your urinary tract and cause a more serious infection in your kidneys called pyelonephritis. If youre pregnant, have underlying health conditions, or are older than 65 years old, you should not try to treat a UTI without antibiotics.

How Are Urinary Tract Infections Diagnosed

Your doctor will use the following tests to diagnose a urinary tract infection:

  • Urinalysis: This test will examine the urine for red blood cells, white blood cells and bacteria. The number of white and red blood cells found in your urine can actually indicate an infection.
  • Urine culture: A urine culture is used to determine the type of bacteria in your urine. This is an important test because it helps determine the appropriate treatment.

If your infection does not respond to treatment or if you keep getting infections over and over again, your doctor may use the following tests to examine your urinary tract for disease or injury:

  • Ultrasound: In this test, sound waves create an image of the internal organs. This test is done on top of your skin, is painless and doesnt typically need any preparation.
  • Cystoscopy: This test uses a special instrument fitted with a lens and a light source to see inside the bladder from the urethra.
  • CT scan: Another imaging test, a CT scan is a type of X-ray that takes cross sections of the body . This test is much more precise than typical X-rays.

Diagnosis Of E Coli Infections

  • Culture of samples of infected tissue

Samples of blood, stool, sometimes urine, or other infected material are taken and sent to a laboratory to grow the bacteria. Identifying the bacteria in the sample confirms the diagnosis.

If E. coli O157:H7 is suspected, doctors do a stool test for Shiga toxins, which are produced by these bacteria. This test provides results quickly.

If E. coli O157:H7 is detected, blood tests must be done frequently to check for hemolytic-uremic syndrome.

Are There Any Over

Over-the-counter antibiotics for a UTI are not available. You should see your doctor to have your symptoms evaluated.

Your provider may recommend an OTC product called Uristat to numb your bladder and urethra to ease the burning pain during urination. Uristat can be bought without a prescription at the pharmacy. A similar phenazopyridine product called Pyridium is also available.

Take phenazopyridine for only 48 hours, and be aware it may cause your urine to turn a brown, orange or red color which may stain fabrics or contact lenses. It may be best to not wear contact lenses while being treated with phenazopyridine.

Phenazopyridine is not an antibiotic and will not cure a UTI.

Who Gets Utis Which Children And Toddlers Are At Risk

Mayo Clinic Minute: Treating Urinary Tract Infections

UTIs are most common in immunosuppressed children and children who have been on antibiotics for a long period of time for other issues. If your child recently went through an organ transplantation, they are also more vulnerable to a urinary tract infection. Children can also be born with abnormalities of their urinary tract that make them more likely to get an infection.

Adults are also vulnerable to urinary tract infections.

Intracellular Bacteria Localization By Laser Confocal Microscopy

Although all the evaluated UPECs were able to enter the eukaryotic cells, confirmation and localization of intracellular bacteria was performed by confocal laser scanning microscopy . Four strains were tested, two of which were negative for the presence of IBC in urine desquamated cells .

After image acquisition and their subsequent analysis, all the strains were observed in small groups, rather than dispersed in the cytoplasm .

Maximum intensity z-projections are shown in the central panel, upper and left are zx and zy, respectively. In red actin staining , in blue DNA , and in green UPEC . UPEC 7, the intracellular bacteria are observed in groups inside the eukaryotic cell resembling IBC. UPEC 144, intracellular bacteria are observed in big groups in a perinuclear localization. UPEC 172, in this case the intracellular bacteria are dispersed in the cytoplasm of the eukaryotic cell. Severe damage is observed as the cells had their membrane damaged and the presence of philopodia this is in agreement with cytotoxicity assay as UPEC 172 had one of the highest values. UPEC 174, disperse intracellular bacteria is observed.

Treatment Options For Dogs With Urinary Tract Infections

Treatment for UTI focuses on managing pain, giving antibiotics for bacterial UTIs. If there is an underlying cause, this must be addressed as well. Dogs with a recessed vulva often benefit from surgery which helps correct this problem. Some dogs with bladder stones can be treated by changing the diet. This helps prevent the future formation of stones in the bladder. For more information on bladder stones, click here!

Talk to your vet about other or alternative treatments such as supplements and/or acupuncture. Cranberry juice has not been proven to help dogs with UTI, but it can be offered to dogs along with their normal bowl of fresh water. Its important to note that cranberry juice or cranberry supplements are thought to improve bladder health and decrease the recurrence of UTI, but they will not cure a current bladder infection.

Make sure that your dog finishes all medications as directed by your vet. If your dog stops eating, has vomiting or diarrhea, or worsening of UTI symptoms while on medication, call your vet right away.

Follow up with your vet to recheck your dogs urine sample once the medication is finished. This will help determine if the UTI has cleared up or if your dog needs to continue treatment.

Carefully Targeted Antibiotic Treatment For Urinary Tract Infections

Amoxicillin Rx, Capsules, 500 mg x 100 ct

So what do we do now? As a society and as individuals, we should reduce and carefully target antibiotic use. Both physicians and patients should be aware of the grave potential to lose effective antibiotics for all infections even simple UTIs. Its an opportunity that empowers individuals to have informed conversations with their doctors. Every time your doctor prescribes an antibiotic, ask: Do I need this? Why? Is there an antibiotic-free alternative? Talking about it might be enough to meaningfully reduce inappropriate antibiotic use.

If youre having UTI symptoms like burning with urination, more frequent urination, bloody or cloudy urine, low abdominal pain, or fever, you should see a medical provider to get tested. Youll have to urinate into a container and the medical office will test for products of bacterial metabolism. Make sure to tell your provider if youve had UTIs before, and what antibiotic you took. If you have a history of antibiotic-resistant infections, share that, too. There are alternatives to Cipro and Bactrim, but antibiotic choices are limited.

If antibiotic resistance continues to grow, more people will need intravenous treatment for UTIs we used to cure with simple oral antibiotic courses. Were also likely to see more complications, like kidney infections and sepsis, arising from ineffective treatment.

    How To Cope With Side Effects Of Amoxicillin

    What to do about:

    • feeling sick â stick to simple meals and do not eat rich or spicy food. It might help to take your amoxicillin after a meal or snack.
    • diarrhoea â drink plenty of fluids, such as water or squash, to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor. If you take contraception and you have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Check the pill packet to find out what to do.

    Who Gets Urinary Tract Infections

    Antibiotic Awareness: Urinary Tract Infection (UTI), Cystitis or Bladder Infection

    Anyone can. But theyre more likely when you:

    • Have something that blocks the passage of urine, such as a tumor, kidney stone, or an enlarged prostate
    • Use a diaphragm or spermicide for birth control
    • Have a catheter, a tube placed into the bladder to drain urine from the bladder into a bag outside the body
    • Are a man who has sex with men, has HIV, or hasnât been circumcised

    Most of these traits also raise the odds that a simple bladder infection may become a more serious kidney infection or turn into . For pregnant women, a kidney infection can lead to delivering a baby too early.

    Managing Multiple Episodes Of Uti:

    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.

    Symptoms To Which You Should Pay Special Attention

    If you need to go to the toilet more often than usual, and you feel pain and stinging when you pass water, you may have a urinary tract infection. If it is very painful, it is advisable to see a doctor. However, cystitis often clears up by itself.

    If you have a high temperature and pain in your lower back, you may have an infection of the renal pelvis, and then it is a good idea to call a doctor.

    Is It Possible To Prevent Recurrent Urinary Tract Infections With A Vaccine

    Currently, there are no commercially available vaccines for UTIs, either recurrent or first-time infections. One of the problems in developing a vaccine is that so many different organisms can cause infection a single vaccine would be difficult to synthesize to cover them all. Even with E. coli causing about most infections, the subtle changes in antigenic structures that vary from strain to strain further complicate vaccine development even for E. coli. Researchers are still investigating ways to overcome the problems in UTI vaccine development.

    What About Cranberry Juice For Uti

    Rx Amoxicillin &  Clavulanate Potassium Tablets, 875mg/125mg, 20 ct

    Its a long-held belief that consuming cranberry juice may help prevent and treat urinary tract infections. While its true that cranberries contain an active ingredient that can prevent adherence of bacteria to the urinary tract, there is still no evidence that cranberry products can treat a UTI.

    One of the reasons: Products like cranberry juice or cranberry capsules are not explicitly formulated with the same amount of PACs that have shown potential in lab studies. Moreover, a 2019 report in the Journal of Urology noted that the availability of such products to the public is a severe limitation to the use of cranberries for UTI prophylaxis outside the research setting.

    In all, theres actually very little high-quality research on the topic of prevention. For instance, a 2016 study in The Journal of the American Medical Association, found that among female nursing home residents, daily consumption of cranberry capsules resulted in no significant prevention of UTIs.

    While consuming cranberry juice or supplements is not considered a first-line treatment of urinary tract infections, in most cases, it cant hurt. After all, drinking plenty of liquids does dilute your urine and help spur more frequent urination, which flushes bacteria from the urinary tract. The exception: Those who are taking blood-thinning medication, such as warfarin, should not consume cranberry juice. And those with diabetes should be mindful of the high-sugar content of fruit juices.
