How Do Antibiotics Treat A Uti
UTIs can be caused by many different types of germs including bacteria or fungi and in rare cases, even viruses. But bacterial UTIs are the most common.
If you have a bacterial UTI, the only way to treat it is by getting rid of the bacteria thats causing it. Thats where antibiotics come in. They either stop those bacteria from growing or directly kill the bacteria altogether.
Its worth noting that antibiotics only treat UTIs and other infections caused by bacteria. If you have a fungal or viral UTI, antibiotics wont help.
Other Health Conditions Of Concern
Keflex may not be a good choice if you have certain health conditions. Be sure to discuss your health history with your doctor before they prescribe Keflex or any other drug to treat your UTI.
Examples of conditions that could cause problems with Keflex include kidney disease and allergies to penicillin or other cephalosporins.
When To Seek Medical Advice
You are at greater risk of developing complications from a UTI and should seek medical advice promptly if you:
- have existing kidney disease, diabetes, or another chronic condition
- are pregnant
- are over the age of 65
- or have one or more of the following symptoms – high temperature , shivering, nausea and/or vomiting, diarrhoea or worsening pain in your abdomen, pelvis or back.

What Is The Urinary Tract
The urinary tract makes and stores urine, one of the body’s liquid waste products. The urinary tract includes the following parts:
- Kidneys: These small organs are located on back of your body, just above the hips. They are the filters of your body removing waste and water from your blood. This waste becomes urine.
- Ureters: The ureters are thin tubes that carry urine from the kidneys to your bladder.
- Bladder: A sac-like container, the bladder stores your urine before it leaves the body.
- Urethra: This tube carries the urine from your bladder to the outside of the body.
What About Cranberry Juice For Uti
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.

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.

Which Antibiotic Should Be Used To Treat A Uti
There are multiple types of antibiotics used to treat urinary tract infections . Different treatments may be recommended in different areas of the country based on regional patterns of antibiotic resistance.
Most patients with an uncomplicated UTI will begin treatment without any special diagnostic test, although a urinalysis may be performed by taking a urine sample. In a urinalysis, the chemical components of the urine are determined, and the doctor may look at urine color, clarity, and a view a sample under the microscope. A urine culture may be order, too, but is not always needed to start treatment. A urine culture can define the specific bacteria causing the UTI in more complicated cases or in the case of treatment failure.
Symptoms like burning and stinging while urinating will usually clear up in within one day after starting treatment. Be sure to finish your entire course of medication. If symptoms are still present after 2 to 3 days, contact your healthcare provider.
More extensive diagnostic procedures or imaging tests like an X-ray may be required if you continue to have frequent UTIs.

Can I Become Immune To The Antibiotics Used To Treat A Uti
Your body can actually get used to the antibiotics typically used to treat a urinary tract infection . This happens in people who have very frequent infections. With each UTI and use of antibiotics to treat it, the infection adapts and becomes harder to fight. This is called an antibiotic-resistant infection. Because of this, your healthcare provider may suggest alternative treatments if you have frequent UTIs. These could include:
- Waiting: Your provider may suggest that you watch your symptoms and wait. During this time, you may be encouraged to drink plenty of fluids in an effort to flush out your system.
- Intravenous treatment: In some very complicated cases, where the UTI is resistant to antibiotics or the infection has moved to your kidneys, you may need to be treated in the hospital. The medicine will be given to you directly in your vein . Once youre home, you will be prescribed antibiotics for a period of time to fully get rid of the infection.

Antibiotics Used For Complicated Utis
Before getting into how to best treat a complicated UTI, its important to understand which UTIs are considered complicated. Here are some guidelines:
- Urinary tract abnormalities are present
- Youre pregnant
- The patient is a child
- A comorbidity is present that increases risk of infection or treatment resistance, such as poorly controlled diabetes
- Youre a man, since most UTIs in men are considered complicated
- Youre elderly
Kidney infections are often treated as a complicated UTI as well, notes the Merck Manual.
If a UTI is complicated, a different course of antibiotics may be required. And the initial dose of antibiotics may be started intravenously in the hospital. After that, antibiotics are given orally at home. In addition, follow-up urine cultures are generally recommended within 10 to 14 days after treatment. Not all of the antibiotics approved for uncomplicated UTIs are appropriate for the complicated version. Some that are considered appropriate, include:
Things You Can Do Yourself
To help ease pain:
- takeparacetamolup to 4 times a day to reduce pain and a high temperature for people with a UTI, paracetamol is usually recommended over NSAIDs such as ibuprofen or aspirin
- you can give childrenliquid paracetamol
- rest and drink enough fluids so you pass pale urine regularly during the day, especially during hot weather
It’s important to follow the instructions on the packet so you know how much paracetamol you or your child can take, and how often.
It may also help to avoid having sex until you feel better.
You cannot pass a UTI on to your partner, but sex may be uncomfortable.
Taking cystitis sachets or cranberry products has not been shown to help ease symptoms of UTIs.

Utis And Ms: How To Prevent This All
Why are people who have MS prone to UTIs? And how can you prevent more of them? Find the answers here.
Canva Everyday Health
At least 80 percent of people who have multiple sclerosis have some bladder dysfunction, which can lead to frequent bladder or urinary tract infections , according to the National Multiple Sclerosis Society .
Its common for people who have MS to have difficulties fully emptying their bladder, which puts them at increased risk of UTIs, notes the NMSS. Urine that stays the bladder too long breeds an abundance of bacteria, which eventually leads to infection. Holding urine also allows mineral deposits to form stones that can lead to infection and irritate bladder tissues.
Talking to your doctor about any bladder dysfunction issues you may have can help stave off repeated UTIs, which can be serious in some cases for people who have MS. Taking steps to prevent UTIs, and seeking prompt diagnosis and treatment when youre having symptoms, can also be helpful.
Common Side Effects With Antibiotic Use
Each antibiotic is responsible for its own unique list of side effects, and the list is usually extensive. Be sure to discuss your individual antibiotic side effects with your healthcare provider. However, there are side effects that are common to most antibiotics, regardless of class or drug:

Bacterial Interference: Escherichia Coli Strain 83972
The intentional colonization of the bladder with a non-virulent strain, also called bacterial interference, has been studied among patients with neurogenic bladder. E. coli 83972 is a clinical strain, isolated from a woman with chronic urinary colonization and which has naturally lost its capacity to develop Type 1 and Type P fimbriae. This strain has been used for prophylactic purposes to deliberately colonized the bladders with this bacterium to prevent colonization/infection by pathogenic species.
In a mouse model of UTI, E. coli 83972 demonstrated a better fitness than a virulent strain of UPEC. In a poor environment, like the bladder, this difference in fitness is a crucial advantage for the competition between bacteria. The 83972 strain could reduce the impact of UTIs by a monopolization of resources and space .
Seven clinical studies are available: three are RCT, one of which is a crossover designed study and four are prospective cohorts . Sample sizes were small and varied from 12 to 44 patients. Clinical endpoints were the interval before first recurrence or the incidence of UTI during follow up.
Despite this heterogeneity, all studies demonstrated the ability of non-virulent strain to protect patients from UTI. One limit is the difficulty to achieve bladder colonization with the non-virulent strain .
What Is The Prognosis For A Person With A Urinary Tract Infection
Urinary tract infections typically respond very well to treatment. A UTI can be uncomfortable before you start treatment, but once your healthcare provider identifies the type of bacteria and prescribes the right antibiotic medication, your symptoms should improve quickly. Its important to keep taking your medication for the entire amount of time your healthcare provider prescribed. If you have frequent UTIs or if your symptoms arent improving, your provider may test to see if its an antibiotic-resistant infection. These are more complicated infections to treat and may require intravenous antibiotics or alternative treatments.

Diagnosis And Treatment Of Urinary Tract Infections In Children
BRETT WHITE, MD, Oregon Health and Science University, Portland, Oregon
Am Fam Physician. 2011 Feb 15 83:409-415.
Acute urinary tract infections are relatively common in children, with 8 percent of girls and 2 percent of boys having at least one episode by seven years of age. The most common pathogen is Escherichia coli, accounting for approximately 85 percent of urinary tract infections in children. Renal parenchymal defects are present in 3 to 15 percent of children within one to two years of their first diagnosed urinary tract infection. Clinical signs and symptoms of a urinary tract infection depend on the age of the child, but all febrile children two to 24 months of age with no obvious cause of infection should be evaluated for urinary tract infection . Evaluation of older children may depend on the clinical presentation and symptoms that point toward a urinary source . Increased rates of E. coli resistance have made amoxicillin a less acceptable choice for treatment, and studies have found higher cure rates with trimethoprim/sulfamethoxazole. Other treatment options include amoxicillin/clavulanate and cephalosporins. Prophylactic antibiotics do not reduce the risk of subsequent urinary tract infections, even in children with mild to moderate vesicoureteral reflux. Constipation should be avoided to help prevent urinary tract infections. Ultrasonography, cystography, and a renal cortical scan should be considered in children with urinary tract infections.
How Should This Medicine Be Used
Phenazopyridine comes as a tablet or capsule to take by mouth. It usually is taken three times a day after meals. Do not chew or crush the tablets as it may cause your teeth to become stained swallow them whole with a full glass of water. You may stop taking this drug when pain and discomfort completely disappear. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take phenazopyridine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

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:
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?
Amoxicillin/potassium Clavulanate Cefdinir Or Cephalexin
How it Works: is another combination drug that belongs to the penicillin class of antibiotics. and belong to a different class of antibiotics thats closely related to penicillins.
All three antibiotics kill bacteria by destroying one of its most important components: the cell wall, which normally keeps bacteria structurally intact.
Common doses:
-
Amoxicillin/clavulanate: 500 twice a day for 5 to 7 days
-
Cefdinir: 300 mg twice a day for 5 to 7 days
-
Cephalexin: 250 mg to 500 mg every 6 hours for 7 days
Notable side effects: Diarrhea, nausea, vomiting, and rash are common side effects of these antibiotics. In rare cases, all three have the potential to cause the dangerous skin reactions, SJS and TEN.
If you have a penicillin allergy, your healthcare provider wont prescribe amoxicillin/clavulanate. They may or may not prescribe cefdinir or cephalexin since there is a small chance that a person with a penicillin allergy may also be allergic to these two.

What Are Utis And Who Should Care
UTIs are infections of the urinary tract. The urinary tract is the system that creates, collects, and gets rid of urine from your body. When bacteria enter the urinary system and find a place to grow, this is called a UTI.
Your urinary tract begins with your kidneys, which create urine. A pair of tubes called ureters carry urine from your kidneys down into your bladder. Urine is held in your bladder until you are ready to empty it. When you go to the bathroom, urine comes out through your urethra, which is the tube that connects your bladder to the outside.
Infections of the kidney, called pyelonephritis, can be quite serious. Bladder infections, called cystitis, are the most common type of UTI. Usually, when people talk about a UTI, they are talking about a bladder infection.
