What Is Best Antibiotic For Bladder Infection

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

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

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.

Best Antibiotics For Utis

A UTI is a common infection of the urinary tract that can affect the kidneys, urethra, bladder, or ureters. They are often caused by bacteria entering the urinary tract, which then multiplies in the bladder. In addition, UTIs can also be caused by viral infections. Your doctor may request special testing if they believe you have a viral UTI, as they are treated with antivirals, not antibiotics. If you have a bacterial UTI, the best course of treatment would be antibiotics.

Dr. David Beatty, a general practitioner for over 30 years, provided insight for this article. Dr. Beatty noted that in an ideal situation, a urine culture is performed to see the specific bacteria causing an infection. A physician can then determine the perfect antibiotic for killing the bacteria. In cases without urine cultures, which happens most often, the following is taken into consideration:

  • Severity of illness

There are some medicines that do not mix well with nitrofurantoin.

Tell your doctor if youâre taking these medicines before you start nitrofurantoin treatment:

  • 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

What Are Prostate Infections And Prostatitis

The prostate gland is a part of a mans reproductive system, secreting fluids that help transport sperm. The gland lies just below the bladder and surrounds the urethra .

Prostate infections may irritate the prostate and cause inflammation and swelling of the gland. Prostate infections occur most often in men aged 30-50 years but can occur in older men. Unfortunately, many people equate the terms prostate infection and prostatitis, but prostate infections comprise only two of the four major classifications of the term prostatitis, and infectious types comprise only a few of the total number of prostatitis diagnosed patients.

The National Institutes of Health consensus panel has designated four types of prostatitis classifications.

  • Acute bacterial prostatitis
  • Chronic prostatitis/chronic pelvic pain syndrome with subtypes of CPPS termed inflammatory and noninflammatory
  • Asymptomatic inflammatory prostatitis
  • The NIH has established extensive criteria for chronic pelvic pain syndrome that excludes infection and other problems and is as follows:

    Inclusion Criteria

    • male, at least age 18
    • pain or discomfort in the pelvic area for at least 3 months

    Exclusion Criteria

    This classification system is important to understand because about 90% of men with prostatitis symptoms are diagnosed with chronic pelvic pain syndrome and, by definition, do not have infectious prostatitis.

    Stress and depression are common in men with chronic infectious prostatitis.

    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.

    What Antibiotics Are Used To Treat Bacterial Utis

    Once your physician has determined the location of your UTI and whether its complicated, he or she will likely suggest an antibiotic for treatment. Infections in the lower urinary tract are typically treated with oral medication , while upper-tract UTIs usually merit intravenous antibiotics.

    All antibiotics require a prescription. This is, in part, to avoid the potential for antibiotic misuse, which can result in your body forming a dangerous resistance to antibiotics. Its also a way to ensure that you visit a healthcare provider when you have symptoms. If left untreated, even an uncomfortable but harmless lower-tract UTI can become more severe, particularly if its allowed to travel further up the urethra and take up residence in your kidneys.

    What Is The Most Effective Antibiotic For Uti

    Mayo Clinic Minute: Treating Urinary Tract Infections
  • What Is the Most Effective Antibiotic for UTI? Center
  • While mild UTIs usually go away on their own with sufficient hydration, most cases of moderate or recurrent UTIs may require medical treatment involving antibiotics and painkillers.

    In order to determine what type of antibiotic you need, a urine sample is needed to identify the type of bacteria infecting your urinary tract. A urine culture is conducted on the sample, examining it for antibiotic sensitivity and specificity. It may take 3-4 days to get the results.

    Doctors do not recommend taking a broad-spectrum antibiotic without a urine culture because doing so may contribute to antibiotic resistance, where the germ becomes stronger than the antibiotic.

    Once the culture results are back, depending on the sensitivity, your doctor may prescribe the following:

He is the current president of the American Society of Veterinary Nephrology and Urology.

    Urinary tract infections are common in small animal practice it has been reported that up to 27% of dogs will develop infection at some time in their lives.1

    Most UTIs are successfully treated with commonly used drugs, dosages, and administration intervals. However, infections can be challenging to effectively treat when they involve the kidneys and prostate . In addition, it can be difficult to create an appropriate antibiotic prescription in patients with kidney disease due to reduced drug clearance.

    Understanding drug pharmacokinetics and pharmacodynamics is essential when determining the most effective antibiotic therapy. In addition, successful antimicrobial therapy requires appropriate choice of antibiotic, including dose, frequency, and duration .

    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.

    Does Cranberry Juice Prevent A Uti

    ASK DIS: Urinary Tract Infection: Antibiotics in Adults

    Some patients may want to use cranberry or cranberry juice as a home remedy to treat a UTI. Cranberry juice has not been shown to cure an ongoing bacterial infection in the bladder or kidney.

    Cranberry has been studied as a preventive maintenance agent for UTIs. Studies are mixed on whether cranberry can really prevent a UTI. Cranberry may work by preventing bacteria from sticking to the inside of the bladder however, it would take a large amount of cranberry juice to prevent bacterial adhesion. More recent research suggests cranberries may have no effect on preventing a UTI

    • According to one expert, the active ingredient in cranberries — A-type proanthocyanidins — are effective against UTI-causing bacteria, but is only in highly concentrated cranberry capsules, not in cranberry juice.
    • However, cranberry was not proven to prevent recurrent UTIs in several well-controlled studies, as seen in a 2012 meta-analysis of 24 trials published by the Cochrane group.
    • While studies are not conclusive, there is no harm in drinking cranberry juice. However, if you develop symptoms, see your doctor. Some people find large quantities of cranberry juice upsetting to the stomach.

    Increasing fluid intake like water, avoiding use of spermicides, and urinating after intercourse may be helpful in preventing UTIs, although limited data is available.

    What Are The Best Antibiotics For A Kidney Infection

    The kidneys are responsible for filtering waste materials from the body and forming urine. When bacteria enter the kidneys, usually through the tube known as the urethra that connects the bladder to the outside of the body, an infection may develop. Antibiotics are almost always used to treat these infections. Some available antibiotics for a kidney infection include fluoroquinolones, beta-lactam antibiotics, trimethoprim, and co-trimoxazole. Choosing the best antibiotics depends upon the severity and frequency of the infections as well as the overall health of the patient.

    Fluoroquinolones are commonly used to treat a kidney infection. These medications are in a class known as broad-spectrum antibiotics. This means they may be used to treat a wide variety of infections, including kidney infections. This type of antibiotic is used primarily when there has been an ongoing history of kidney problems. A rash resembling measles may occur in some patients taking this type of antibiotic.

    Amoxicillin/potassium Clavulanate Cefdinir Or Cephalexin

    What are some common antibiotics used to treat UTIs?

    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.

    Monitoring Response To Therapy

    Patients with a simple, uncomplicated UTI may not require rigorous monitoring. However, patients with complicated, relapsing, or recurrent infections should be monitored very closely. The following protocol is recommended to monitor response to therapy in patients with relapsing, recurrent, or refractory UTI.3

  • Recheck urine culture 5 to 7 days into antibiotic therapy. This confirms that the prescribed dose and frequency of the drug were successful in treating the organism isolated. This culture also may reveal an additional isolate that could not be identified in the initial culture. Any bacterial growth observed at this time suggests treatment failure. Reconsider the choice of antibiotic, dose, and administration frequency.
  • Recheck urine culture 3 days before discontinuing antibiotic therapy. This is an optional step, but it confirms that, when therapy was discontinued, the patient still had a negative culture. Positive bacterial growth at this stage suggests a refractory infection or newly inoculated organism. Investigate patients for any nidus of infection . Alter treatment and institute new therapy for the same duration as previously intended.
  • Recheck urine culture 7 days after discontinuing antibiotic therapy. Positive growth should prompt investigation for causes of relapse or reinfection.
  • Which Antibiotics Are Most Effective In The Treatment Of Prostatitis

    Nitrofurantoin, sulfonamides, vancomycin, penicillins, and cephalosporins do not penetrate well into the prostate.

    Antibiotics that penetrate well into the acid milieu of the prostate are nonpolar and lipid-soluble and have a high measure of acid strength, a small molecular radius, and low serum protein binding. Drugs that best fit these criteria are the fluoroquinolones, doxycycline, minocycline , trimethoprim , rifampin, and erythromycin. Of this group, the fluoroquinolones appear to achieve the best tissue levels.

    Erythromycin is used as a second-line agent when culture results are available.
