Does Macrobid Help Kidney Infections

What Causes A Kidney Infection

Urinary Tract Infections, Animation.

Most kidney infections develop from a bladder infection . Bacteria travel up the tube between the bladder and kidney to infect a kidney. These bacteria are usually those normally living in the bowel eg, E. coli. Most people with cystitis dont get a kidney infection.

Some kidney infections develop without a bladder infection. This is sometimes due to a problem in the kidney. For example, people are more prone to kidney infections if they have a kidney stone or an abnormality of the kidney.

Kidney infections are also more common in children, in older people and during pregnancy. They are uncommon in men.

I Still Have A Uti After Finishing A Course Of Antibiotics Why Didnt Drug Kill It All Off


Im 25 and not sexually active. After having a burning discomfort down there and lower back pains that my doctors were ignoring for weeks to months they finally did a test and discovered I had a UTI. I was put in Macrobid/ nitrofutonin 100mg 1 pill twice a day for 5 days. I took the medicine EXACTLY as prescribed. I was drinking both cranberry juice and water to flush it out completely. I did notice an immediate difference in the pain when I was taking the antibiotics. However, by the 4th day of treatment I noticed My infection stopped responding to the antibiotics. So I just assumed maybe its residual burning and irritation from having a UTI for awhile. Plus I thought once I finish the course maybe it needed time to kick in so waited a few weeks to see if there would be difference.

    You may need a different antibiotic. I, too, was on the nitrofutonin, and it didnt get rid of it. The dr. prescribed Amoxicil which took care of it. In the past, I have also been prescribed Cipro which would knock it out fast. The last infection i had which was about 2 months ago, was really hard to get over. I ended up having an ultrasound/ cystoscopy which were normal. The symptoms remained yet no infection. My urologist seems to believe I may have had an allergic reaction to the lubricant used f/ my pap smear. I am just now beginning to feel better.

  • What Conditions Can It Treat

    Nitrofurantoin is prescribed to treat UTIs, which fall into two major categories:

    • Lower tract UTIs: Also called bladder infections, these are the most common type of urinary tract infections and also the easiest to treat. They occur in the lower urinary tract, meaning the area from the urethra up to the bladder.
    • Upper tract UTIs: These more serious forms of UTIs are also known as kidney infections. Upper UTIs usually result from untreated lower UTIs that spread upward to the kidneys. Symptoms include nausea, fever, body chills, and lower back or side pain. Kidney infections can be treated with antibiotics but in severe cases may require a trip to the hospital to prevent permanent organ damage or renal failure.

    Nitrofurantoin is primarily prescribed to treat uncomplicated lower urinary tract infections. A UTI is considered uncomplicated if someone has no urinary tract abnormalities or underlying health issues. If you are prone to recurrent UTIsmeaning you get two or more in six months or three or more in a yearyour doctor might prescribe nitrofurantoin in a smaller dose over a longer period of time to prevent UTIs.

    Kidney Function And The Use Of Nitrofurantoin To Treat Urinary Tract ...

    Treating kidney infection solely at home or with natural remedies is not a good idea. However, several home remedies can help manage the pain while the infection is treated with antibiotics. These include drinking water, using a heating pad to reduce pain, and taking over-the-counter acetaminophen to manage both pain and fever.

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

    Tell your doctor if youre 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

    Which Drugs Interact With Nitrofurantoin

    • High doses of probenecid or sulfinpyrazone can partially block the kidneys’ elimination of nitrofurantoin. This can increase the blood concentrations of nitrofurantoin and the risk of toxicity from nitrofurantoin.
    • Concomitant administration of a magnesium trisilicate antacid may decrease the absorption of nitrofurantoin, reducing the effectiveness of nitrofurantoin.
    • Nitrofurantoin may reduce the activity of live tuberculosisvaccine and live typhoid vaccine. In laboratory tests, nitrofurantoin reduced the effect of quinolone antibiotics, for example, norfloxacin . Therefore, nitrofurantoin should not be combined with quinolone antibiotics.

    Does Enterobacter Cause Uti

    In both the community and the clinical environment, Enterobacteriaceae are the most prevalent causes of urinary tract infections . In fact, 90% of all UTIs are caused by these bacteria. The other 10% of cases may be caused by other organisms such as Candida or Pseudomonas.

    Enterobacter causes about 15% of all UTIs in adults who go to their doctor with symptoms of a bladder infection. This figure increases to 25% for people who do not report symptoms but still have evidence of infection. Children can get enterobacteria from their parents urine or feces. Therefore, children often get UTIs due to enterobacteria even if they appear healthy and no one has reported any signs of illness. Parents should take precautions so that this does not happen.

    Enterobacter is a common bacterium found in the intestines of humans and other animals. It plays an important role in digestion by breaking down food into nutrients that can be absorbed by the body. However, when enterobacteria invade the urinary system they can cause problems such as cystitis and pyelonephritis. This occurs when the bacteria infect the kidneys.

    Treatment for enterobacterial infections includes antibiotics.

    Older women with urinary tract infections who are taking the commonly prescribed antibiotic nitrofurantoin are more likely to experience treatment failure, resulting in a second antibiotic prescription or a hospital visit, than if they received another antibiotic, according to research in CMAJ .

    More than 25% of older adults have low kidney function, and bladder infections are common. Nitrofurantoin is one of the most commonly prescribed antibiotics for bladder and other urinary tract infections, with an estimated 25 million prescriptions worldwide each year. However, there is a concern that less of the drug reaches the urinary space in patients with low kidney function, rendering it unable to work against the bacteria that cause bladder infections. It is recommended that nitrofurantoin be avoided in people with low kidney function, although the evidence for this recommendation is weak and based on small studies.

    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.
