Most Used Antibiotic For Uti

International Clinical Practice Guidelines

Urinary Tract Infection (UTI) Treatment | How to Treat UTI | Nitrofurantoin (Macrobid) | Most Common

In 2010, a panel of international experts updated the 1999 Infectious Diseases Society of America guidelines on the treatment of acute uncomplicated cystitis and pyelonephritis in women. The panel reviewed the literature, including the Cochrane Database of Systematic Reviews, and provided an evidence-based guideline for women with uncomplicated bacterial cystitis and pyelonephritis.16,17 The IDSA collaborated with the European Society of Clinical Microbiology and Infectious Diseases, and invited representation from diverse geographic areas and a wide variety of specialties, including urology, obstetrics and gynecology, emergency medicine, family medicine, internal medicine, and infectious diseases. Levels-of-evidence ratings were assigned to recommendations on the use of antimicrobials for the treatment of uncomplicated UTIs.

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.

Could My Uti Symptoms Be A Sign Of Anything Else

Sometimes symptoms can be mistaken for a UTI but actually be caused by something else. For example, pain, burning, and stinging when passing urine can also be a sign of chlamydia, so it is important to exclude this if you are at risk.13

Needing to pass urine very frequently may also be a sign of other conditions, such as type 1 diabetes, although this is much less common than UTIs. However, it may be considered if other symptoms are present, like feeling thirsty very often.

Other less common conditions can also cause an increase in the frequency of passing urine, including a high blood level of calcium, and some medications. Blood in the urine can be a sign of lots of things other than a UTI, including kidney stones, STIs, and problems with the anatomy of the urinary tract. An examination from a medical professional and common tests if necessary can help distinguish between a UTI and another cause.

Generally speaking, UTIs are very treatable and wont always need antibiotics it just depends on the severity of your symptoms. However, if you experience symptoms and are unsure, it is always best to visit your doctor to be on the safe side, as some types of UTIs always need antibiotics.

Treatment For Complicated Utis

If your UTI is considered complicated due to extenuating circumstances, your doctor will likely still prescribe an antibiotic, but your course of treatment may be different. For example, while UTIs are common during pregnancy especially in the lower urinary tract pregnant women typically require a longer course of treatment, regardless of which type of antibiotic is used. The antibiotics prescribed vary according to which trimester the expectant mother is in, too. TMP, for instance, isnt used during the first trimester.

In short, if your UTI is informed by extenuating circumstances, expect your physician to take those into account as he or she determines what antibiotics may be the safest and most effective, as well as how long you need to take them.

What Are The Best Antibiotics For UTI In Males?

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.

Urine Drug Concentration And 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.

How Do I Know If My Particular Strain Of Uti Is Resistant To A Particular Drug

The only way is to get a urine culture. The lab results will identify the germ and what would be effective in treating the infection. But it can take several days to get the results.

Most patients want an immediate prescription so doctors usually make a best-guess determination of what drug will work given a patients symptoms and history.

The importance of history cannot be overstated if you have had a previous U.T.I., a previous resistant U.T.I., or have traveled outside the country, your history can help a doctor decide which drug to use.

Increasingly, experts tell us that you should ask for a culture when you go in for a U.T.I. treatment, even if you get an immediate prescription. The culture will allow a doctor to change the drug if the first one does not work.

That said, there is an important catch about when to do a urine culture. Often, it will show bacteria in the bladder even when an infection is not present. Some amount of bacteria is normal. The Infection Disease Society of America cautions doctors against doing cultures when symptoms of a U.T.I. are not present. The culture likely presence of bacteria can then lead to prescription of unnecessary antibiotics, contributing to the rise of resistance through overuse of the drugs.

Finally, some U.T.I.s, even when there are symptoms, can clear up on their own. This is one of many reasons to seek the care of an informed professional.

What Oral Antibiotics Are Used To Treat An Uncomplicated Uti In Women

The following oral antibiotics are commonly used to treat most uncomplicated UTI infections :

Your doctor will choose your antibiotic based on your history, type of UTI, local resistance patterns, and cost considerations. First-line options are usually selected from nitrofurantoin, fosfomycin and sulfamethoxazole-trimethoprim. Amoxicillin/clavulanate and certain cephalosporins, for example cefpodoxime, cefdinir, or cefaclor may be appropriate options when first-line options cannot be used.

Length of treatment for cystitis can range from a single, one-time dose, to a course of medication over 5 to 7 days. Kidney infections may require injectable treatment, hospitalization, as well as a longer course of antibiotic, depending upon severity of the infection.

Sometimes a UTI can be self-limiting in women, meaning that the body can fight the infection without antibiotics however, most uncomplicated UTI cases can be treated quickly with a short course of oral antibiotics. Never use an antibiotic that has been prescribed for someone else.

In men with symptoms that do not suggest a complicated UTI, treatment can be the same as women. In men with complicated UTIs and/or symptoms of prostatitis are not present, men can be treated for 7 days with a fluoroquinolone . Tailor therapy once urine cultures are available.

  • 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 Are Risk Factors For Recurrent Utis

  • Having had a UTI in the past

  • Incomplete emptying of the bladder, such as after menopause

  • A weakened immune system

The influence of these risk factors also differs for women depending on their age. In young, pre-menopausal women, the most common risk factor for recurrent UTIs is frequency of sexual intercourse. Having sex more than 9 times a month makes them twice as likely to have recurrent UTIs compared to having sex 4 to 8 times in a month.

In postmenopausal women, the strongest risk factor is related to the ability to empty the bladder. If you have urinary incontinence or a condition that keeps you from being able to completely empty your bladder, your risk of recurrent UTIs is higher.

If you have recurrent UTIs, your healthcare provider may suggest antibiotics for prevention. That means youd be taking an antibiotic regularly to prevent another UTI, rather than treat an existing one.

Cephalosporins As Antibiotics For Uti

Cephalosporins are divided into four different generations according to their spectrum of activity against Gram negative bacteria. They have some chemical and pharmacological properties similar to these of penicillin.

Cephalosporins have a broad spectrum against Gram+ and Gram- bacteria, what made them a treatment of choice in UTIs resistant to Amoxicillin and Trimethoprim-sulfamethoxazole. But, this tend to change due to overuse of cephalosporins and development of resistance.

Types of Cephalosporins used as antibiotics for UTI:

  • First generation: cefadroxil , cefazolin , cephalexin , cephradine
  • Second generation: cefaclor , cefamandole , cefotetan , cefoxitin , cefuroxime
  • Third generation: cefdinir , cefixime , cefoperazone , ceftazidime , ceftriaxone
  • Fourth generation: cefepime

The adverse effects of cephalosporins are as follow:

  • GI: diarrhea, nausea, vomiting, abdominal pain
  • CNS: headache, dizziness, weakness
  • Hematology: leukopenia, thrombocytopenia, agranulocytosis, anemia

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

The majority of urinary tract infections are now resistant to one or more antibiotics. The drug ampicillin, once a common treatment, has been largely abandoned because most U.T.I.s are now resistant to it.

The most important question isnt whether an infection is resistant to any drug, but whether it is resistant to the drugs that are commonly used to treat your particular infection.

When experts in the field think about resistant U.T.I.s, they say that resistance depends on the bug and the drug. What that means is that they try to figure out which particular germs are resistant to specific medications.

For patients suffering from a bacterial UTI, they may be curious about what antibiotics are the best for treating their infection.

What About Antibiotic Resistance

Resistance rates for antibiotics are always variable based on local patterns in the community and specific risk factors for patients, such as recent antibiotic use, hospital stay or travel. If you have taken an antibiotic in the last 3 months or traveled internationally, be sure to tell your doctor.

High rates of antibiotic resistance are being seen with both ampicillin and amoxicillin for cystitis , although amoxicillin/clavulanate may still be an option.
