What Is The Best Antibiotic For Urinary Tract Infection

Ask Dr. Nandi: Antibiotic-resistant urinary tract infections are on the rise

The urinary tract is comprised of the ureters , kidneys, bladder, and urethra . Urinary tract infections wake forest nc are most commonly located in the urethra and bladder and while typically caused by bacteria, UTIs can also be viral or fungal. For patients suffering from a bacterial UTI, they may be curious about what antibiotics are the best for treating their infection.

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.

Antibiotics For More Complicated Urinary Tract Infections

A different antibiotic may be better for a more severe or stubborn UTI. This may include a UTI that:

Spreads to the kidneys
Comes back
Is not responding to treatment

Additionally, there is a medical category of complicated UTIs that may require a different antibiotic regimen.

Complicated UTIs include UTIs that occur:

In a person with a childhood history of UTIs
In a person with a weakened immune system
In a child or postmenopausal woman
During pregnancy
With a medical condition, like diabetes
With an abnormality of the urinary tract, like a stone, obstruction, catheter or kidney deformity

In these cases, a urine culture may be done to make the choice of antibiotic. A urine culture grows the bacteria from the urine so that it may be identified under a microscope and tested for antibiotic sensitivity. The best antibiotic will be determined by the culture and sensitivity results.

No matter what antibiotic your health care provider prescribes, it is important to take the entire course as directed. Stopping early can lead to antibiotic resistance.

If your antibiotic doesnt seem to be working and symptoms dont go away or come right back, let your health care provider know.

Can I Become Immune To The Antibiotics Used To Treat A Uti

Antibiotic Treatment of Febrile Urinary Tract Infection ...

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.

indigestion remedies known as antacids, particularly those that contain magnesium
certain medicines for gout, including probenecid or sulfinpyrazone
cystitis remedies you can buy from a pharmacy
antibiotics known as quinolones, including nalidixic acid, ciprofloxacin, levofloxacin, norfloxacin, ofloxacin and moxifloxacin

Typhoid vaccine given by mouth may not work properly if you’re taking nitrofurantoin. This does not apply to typhoid vaccines given by injection.

Can I Prevent A Urinary Tract Infection

Creating Stronger Strains Of Bacteria

Over time, some species of bacteria have become resistant to traditional antibiotics. According to some research , several species of E. coli, the primary cause of UTIs, are showing increasing drug resistance.

The more a person uses an antibiotic, the greater the risk of the bacteria developing resistance. This is even more likely when people do not follow a doctors instructions to complete the full prescribed course of treatment.

It is essential to continue a course of antibiotics until the end date that the doctor provides. People should also never share antibiotics with others.

Can A Uti Go Away On Its Own

Treatment of Urinary Tract Infections with Antibiotics

While most patients with a UTI will be prescribed antibiotics, the truth is, uncomplicated urinary tract infections are often self-limiting, meaning they can potentially run their course sans antibiotic treatment, noted a 2018 report in PLoS Medicine.

In fact, that same report found that more than one-half of the women studied experienced a UTI resolution without the use antibiotics. However, since kidney infections occurred in 7 out of 181 women using ibuprofen, the researchers concluded that, at this time, they cannot recommend ibuprofen alone as initial treatment to women with uncomplicated UTIs.

A better idea, for now: Simply wait until a positive urine culture comes back before treating with antibiotics.

How Do I Know If The Treatment Isnt Working

If the treatment isnt working, your symptoms will stay the same, get worse, or you will develop new symptoms. Call your doctor if you have a fever , chills, lower stomach pain, nausea, and vomiting. You should also call your doctor if, after taking medicine for 3 days, you still have a burning feeling when you urinate. If you are pregnant, you should also call your doctor if you have any contractions.

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.

Urine Drug Concentration & Clinical Efficacy

Antimicrobial drugs must achieve an adequate urine concentration, which must be maintained for a sufficient time for a drug to be effective in treating UTI.16 It has been suggested that clinical efficacy is observed when the urine drug concentration is maintained at a concentration 4-fold higher than the isolates MIC throughout the time between doses.9

Experimental studies in rats have shown that the time for which the plasma drug concentration exceeds the isolates MIC correlates to the magnitude of bacterial colony count reduction the longer the time for which the drug concentration remained above the MIC, the lower the urine colony counts.12 Successful eradication of bacteria within the renal parenchyma or urinary bladder wall is correlated to the plasma, not urine, drug concentration.

When prescribing time-dependent antibiotics, shortening the interval between drug administration is the most effective method to allow the tissue/urine drug concentration to exceed the MIC for the majority of the dosing interval.

Drug elimination follows first-order kinetics, where 50% of the drug is lost in 1 half-life.
In contrast, doubling the dose would only add 1 half-life to the dosing interval.
To add 2 half-lives to the dosing interval, the initial dose would have to be increased 4-fold. The peak serum drug concentration achieved by this approach may exceed the window of safety, producing adverse drug effects.

What Happens When A Uti Goes Untreated

Thanks to early diagnosis and proper treatment, the vast majority of lower urinary tract infections result in no complications. However, if left untreated, a UTI can have serious ramifications notes the Mayo Clinic, including:

Recurrent UTIs
Premature birth and low birth weight
Kidney damage, which can occur is an untreated UTI spreads from the bladder to the kidneys.

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:

What Is The First

First-line antibiotics for acute, uncomplicated urinary tract infections typically include:

Fosfomycin

Cost of generic
First
100 mg twice daily for 5 days	$55
400 mg orally 2-3 times daily for 3-7 days	NA in the U.S.
Trimethoprim/sulfamethoxazole	160/800 mg twice daily for 3 days	$17
250 mg twice daily for 3 days	$26
Ciprofloxacin, extended release	500 mg daily for 3 days	$57
250 mg daily for 3 days	NA

500/125 mg twice daily for 7 days	$32
300 mg twice daily for 10 days	$40
100 mg twice daily for 7 days	$71

Since there is a lower chance of antibiotic resistance with nitrofurantoin and fosfomycin as compared to other classes of antibiotics, they are often used as first-line antibiotics for the treatment of UTI.

However, for severe UTI with complications, fosfomycin or nitrofurantoin may not be effective.

First Line Antibiotics For A Uti

What If I Forget To Take It

If you forget to take a dose, take one as soon as you remember, unless it’s nearly time for your next dose. In this case, just leave out the missed dose and take your next dose as normal.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

Are There Natural At

Yes. While taking antibiotics is still considered the gold standard of UTI treatments, there are some things you can do at home that help relieve symptoms, as well. These include:

Drink plenty of water. Consuming at least six to eight 8-ounce glasses of water daily can help flush away UTI-causing bacteria, setting you up for a quicker recovery. Plus, the more you drink, the more youll have to urinate.
Urinate often. Each time you empty your bladder, youre helping to flush bacteria out of your system.
Try heat. Applying a heating pad to your pubic area for 15 minutes at a time can help soothe the pressure and pain caused by UTI-related inflammation and irritation.
Tweak your wardrobe. Wearing loose cotton clothing and underwear can help you recover from a UTI.
Go fragrance-free. Make sure your personal hygiene products are fragrance-free to sidestep further irritation, notes the National Institute of Diabetes and Digestive and Kidney Diseases.
Cut out certain irritants. Caffeine, alcohol, spicy food, raw onions, citrus fruits, carbonated drinks, artificial sweeteners, and nicotine can further irritate your bladder, making it more difficult for your body to heal, per the Cleveland Clinic.

Clinical And Patient Characteristics

A total of 18 practices took part in the study, and 131 women were included. We excluded 11 patients due to screening failure or technical reasons, such as missing or erroneous data, resulting in a valid sample of 120 women with a total of 769 symptom reports across 7days of measurement. The womens mean age was 43.3±16.6years 62% of them were employed, 77% lived in a partnership, 68% had children, 16% were pupils, 6% were homemakers and 13% were retired. One-third reported that the symptoms lasted no longer than 2days, another third had symptoms for 3 to 5days, while 98 expected to have a UTI, and 25% felt feverish.

History And Physical Examination

ASK DIS: Urinary Tract Infection: Antibiotics in Adults

Clinical signs and symptoms of a UTI depend on the age of the child. Newborns with UTI may present with jaundice, sepsis, failure to thrive, vomiting, or fever. In infants and young children, typical signs and symptoms include fever, strong-smelling urine, hematuria, abdominal or flank pain, and new-onset urinary incontinence. School-aged children may have symptoms similar to adults, including dysuria, frequency, or urgency. Boys are at increased risk of UTI if younger than six months, or if younger than 12 months and uncircumcised. Girls are generally at an increased risk of UTI, particularly if younger than one year.3 Physical examination findings can be nonspecific but may include suprapubic tenderness or costovertebral angle tenderness.
