What Antibiotics Treat Uti And Bladder Infections

Must Read

Creating Stronger Strains Of Bacteria

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

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.

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.

Cephalexin For Chronic Uti

If this is not your first UTI, know one thing: you may not be fighting single-celled free-floating bacteria in your bladder. Most likely, you are fighting bacterial biofilms.

Cephalexin stops the growth of the cell wall, which bacteria need to survive. However, bacteria eventually learn how to hide from the antibiotic attack, allowing them to become resistant to Cephalexin.

One method is for them to team up, cover themselves with a protective slime, and hide in the deeper layers of your bladder lining. This allows bacteria to wait until you stop taking antibiotics before renewing their activity.

This bacterial method of defense is called bacterial biofilms.

How Long Do You Need To Take Antibiotics For A Uti

Antibiotics are typically prescribed for 3-7 days. The course may be extended or the prescription may change if the initial course fails to treat the infection.

For antibiotic therapy to be effective, you need to take the drugs as instructed. Many times, symptoms may seem to resolve before you complete the entire course of antibiotics. However, avoid discontinuing the course of treatment and continue to take the doses as prescribed.

If you are a female and suffer from frequent UTIs, your doctor may ask you to:

  • Take a single dose of antibiotic after intercourse
  • Take low-dose antibiotics for up to 5 months
  • Undergo vaginal estrogen therapy if you are menopausal

How Do Antibiotics Treat A Uti

Episode 69  Urinary Tract Infections

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.

What If Its Not A Uti

If you have symptoms of a UTI, chances are thats what youre dealing with. In some cases, though, these symptoms can also be signs of more serious health conditions.

Other conditions that can cause similar symptoms include:

  • Bladder or kidney cancer

A family history, physical exam, and lab tests can help your doctor determine the next steps and potential causes of your lingering UTI symptoms.

Can I Prevent A Urinary Tract Infection

You can usually prevent a urinary tract infection with lifestyle changes. These tips can include:

In some post-menopausal women, a healthcare provider may suggest an estrogen-containing vaginal cream. This may reduce the risk of developing a UTI by changing the pH of the vagina. Talk to your healthcare provider if you have recurrent UTIs and have already gone through menopause.

Over-the-counter supplements are also available for UTIs. These are sometimes recommended for people who have frequent UTIs as another way to prevent them. Talk to your healthcare provider before starting any supplements and ask if these could be a good choice for you.

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.

A Pharmacist Can Help With Utis

Why is it important to treat UTIs with antibiotics?

You can ask a pharmacist about treatments for a UTI. A pharmacist can:

  • offer advice on things that can help you get better
  • suggest the best painkiller to take
  • tell you if you need to see a GP about your symptoms

Some pharmacies offer a UTI management service and can prescribe antibiotics if they’re needed.

Consider Switching Birth Control

Some older research suggests that certain contraceptives may contribute to the cause of UTIs in some women.

If you use diaphragms, spermicides, or nonlubricated condoms and get frequent UTIs, it may be worth talking to your doctor to find other methods of birth control.

Its not uncommon for UTIs to go away on their own with at-home care and without the use of antibiotics.

Some research estimates that 25 to 42 percent of UTIs can go away on their own. This is usually only common in women with no other health issues.

However, there are some serious risks that can come from leaving a UTI untreated, including pyelonephritis and .

UTIs are painful, but with treatment, you can alleviate an infection and prevent recurrent infections. Talk with your doctor if you have symptoms of a UTI. With proper treatment, you should begin to feel better in a few days.

Take your antibiotics as instructed even after your symptoms improve to prevent complications or a secondary infection.

If the UTI doesnt resolve after antibiotic treatment or you end up with multiple episodes of a UTI, your doctor will likely do further testing.

This could be in the form of:

You may be referred to a urologist, depending on the severity of your UTI or if you have chronic infections.

Certain strains of bacteria can cause UTIs. They can range from mild to severe. The degree of severity depends on multiple factors, including:

Other Antibiotics And Treatments For Urinary Tract Infections

Other antibiotics may be as effective as first-line antibiotics but have more side effects or risks of complications. They are not commonly used. They include:

  • Fluoroquinolones
  • Ciprofloxacin
  • Levofloxacin

Antibiotics called beta-lactams may be used when other first-line antibiotics are unavailable or cannot be used for any other reason. They include:

  • Amoxicillin-clavulanate
  • Cefdinir
  • Cefaclor

These are not usually first-line choices because they are broad-spectrum antibiotics that have a higher risk of causing antibiotic resistance.

Another drug that is frequently prescribed for a UTI is phenazopyridine, available under several brand names such as Pyridium. This medication is not an antibiotic and does not cure a UTI. It is used to relieve symptoms of pain, burning, urgency and pressure.

Treatment For Underlying Conditions

Underlying conditions such as Cushings or diabetes can lead to the recurrence of urinary tract infections in dogs. If your dog has an underlying health condition, treatment may primarily focus on the underlying condition as a means of preventing infection. In some dogs, the prostate disease can be controlled with surgical castration or chemicals, and the growth of bladder tumours can be slowed with medications.

How Are Urinary Tract Infections Diagnosed

Antibiotics recommended for the treatment of urinary tract infections ...

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.

  • Why Do Antibiotics Sometimes Not Work For A Urinary Tract Infection

    What are some common antibiotics used to treat UTIs?

    If an antibiotic doesnt work it is likely that the bacteria causing the UTI is not susceptible or is resistant to the antibiotic you are taking.

    Antibiotic resistance occurs when the bacteria that is causing the infection is no longer affected by a particular antibiotic and is able to continue to grow and multiply. Inappropriate and unnecessary antibiotic use contributes to the increasing problem of antibiotic resistance.

    If you felt better for a little while and then came down with the symptoms of a UTI again, it is also possible that you have a new or recurrent UTI.

    Another possibility if you continue to experience symptoms of a UTI despite antibiotic treatment, is that you have another type of infection that mimics that symptoms of a UTI and you need a different antibiotic or other treatment. Sexually transmitted infections such as chlamydia and gonorrhea, for example, produce symptoms that mimic a UTI. Vaginal yeast infections can also cause burning when you pee.

    What Causes A Urinary Tract Infection

    Urinary tract infections are caused by microorganisms usually bacteria that enter the urethra and bladder, causing inflammation and infection. Though a UTI most commonly happens in the urethra and bladder, bacteria can also travel up the ureters and infect your kidneys.

    More than 90% of bladder infection cases are caused by E. coli, a bacterium normally found in the intestines.

    Does Cranberry Juice Prevent A Uti

    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.

    Practice Good Sexual Hygiene

    The also says that sexual intercourse introduces bacteria and other microbes from outside the body to the urinary tract. Practicing good sexual hygiene can help to reduce the number of bacteria that people can transfer during intercourse and other sexual acts.

    Examples of good sexual hygiene include:

    • urinating before and immediately after sex
    • using barrier contraception, such as a condom
    • washing the genitals, especially the foreskin, before and after engaging in sexual acts or intercourse
    • washing the genitals or changing condoms if switching from anal sex to vaginal sex
    • ensuring that sexual partners are aware of any current or previous UTIs

    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.

    Cephalexin & Uti: My Experience

    I had my share of UTIs several years ago. Fortunately, I was able to get rid of this chronic problem, mostly by relying on a specific type of probiotics and some lifestyle changes.

    If this is your first UTI and you are treating it with Cephalexin, there is no guarantee that the UTI wont come back.

    Remember, the antibiotics will kill the bacteria that invaded your bladder, but antibiotics will not address any of the underlying health conditions that may have caused the UTI in the first place.

    If you do not want to experience the horrors of UTI again, make sure to implement smart prevention strategies, and do not rely solely on the antibiotics. Here are some tips to get you started:
