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.
When To See A Gp
Women do not necessarily need to see a GP if they have cystitis, as mild cases often get better without treatment.
Try some self-help measures or ask a pharmacist for advice.
See a GP if:
- you’re not sure whether you have cystitis
- your symptoms do not start to improve within 3 days
- you get cystitis frequently
- you have severe symptoms, such as blood in your urine, a fever or pain in your side
- you’re pregnant and have symptoms of cystitis
- you’re a man and have symptoms of cystitis
- your child has symptoms of cystitis
A GP should be able to diagnose cystitis by asking about your symptoms.
They may test a sample of your urine for bacteria to help confirm the diagnosis.
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.

Implications For Research And Practice
Based on the data we analysed, a pragmatic approach is required when considering prescribing long-term antibiotics in older patients with recurrent UTI. Although long-term antibiotics may reduce the risk of UTI recurrence in women, this benefit diminishes on cessation of treatment. Little is known about optimal prophylaxis period, long-term effects on health, risk of antibiotic resistant infections, effect in older men, effect in frail care home residents or impact on important patient-centred outcomes. These unknowns must be balanced against benefits and patient preferences.
Future research efforts on recurrent UTI should focus on improving the design and reporting of trials and developing a core set of outcomes to allow better synthesis of trial data. Antibiotic prophylaxis should be compared with non-antibiotic prophylaxis with some evidence of efficacy rather than those with little or poor evidence of efficacy. Researchers should address unanswered questions regarding long-term effects, duration of use, adverse effects and antibiotic resistance.
Bottom Line: Seek Treatment For A Uti Immediately
Antibiotics can be really powerful when it comes to treating urinary tract infectionsespecially when they are caught early. Untreated UTIs can lead to kidney infections and other serious complications. So, when you feel like you have one, go see your primary care doctor as soon as you can, and talk about which treatment would be best for you.

What Are Potential Side Effects Of Antibiotics For Uti
In addition to the notable side effects weve already covered, there are a few more potential antibiotic side effects youll want to know about.
Most antibiotics can cause some degree of stomach upset like nausea, vomiting, and/or diarrhea. If you have severe diarrhea or diarrhea that lasts for 2 or more days, let your healthcare provider know. Diarrhea is a common side effect while taking antibiotics and just after finishing them. But in some cases, diarrhea from antibiotics can be a sign of a more serious infection caused by Clostridium difficile bacteria.
Some people are also sensitive to antibiotics, which could result in a minor reaction like a rash or a more serious reaction like anaphylaxis. If you notice difficulty breathing or major skin changes after taking an antibiotic, get medical help right away.

Which Antibiotic Will I Be Prescribed
Uncomplicated UTIs are most commonly treated with a three day course of one of two antibiotics: trimethoprim or nitrofurantoin.

If this test is positive and symptoms are suggestive of a UTI, the urine sample probably wont be sent off to the labs for further testing, as there is no real need for this.11
Understanding Drug Pharmacokinetics And Pharmacodynamics Is Essential When Determining The Most Effective Antibiotic Therapy For Utis In Dogs And Cats

If you are pregnant, have a high fever, or cannot keep food and fluids down, your doctor may admit you to the hospital so you can have treatment with intravenous antibiotics for a complicated UTI. You may return home and continue with oral antibiotics when your infection starts to improve.
In areas with fluoroquinolone resistance exceeding 10%, in patients with more severe pyelonephritis, those with a complicated UTI who have allergies to fluoroquinolones, or are unable to tolerate the drug class, intravenous therapy with an agent such as ceftriaxone, or an aminoglycoside, such as gentamicin or tobramycin, may be appropriate. Your ongoing treatment should be based on susceptibility data received from the laboratory.

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.

What Are The Most Common Causes Of Utis
Most of the time when you go #1, what flows out flushes away some of the troublesome microbes hanging out around your nether region.
Usually urine is sterile so theres no bacteria in it, explains Sabitha Rajan, M.D., MSc, associate managing editor at MCG. One of the things that keeps us sterile is its continuous flow. Urine flows out of your bladder, down and out your urethra , and that flow keeps any bacteria from the outside from ascending.
Proper hygiene helps keep bacteria at bay but even the cleanest among us can get a UTI. Keep an eye out for these common symptoms:
- A burning sensation when peeing
- A frequent urge to urinate
- Bloody or cloudy urine
- Bladder cramps or pelvic pain
- And in the worst cases: fever, vomiting, and nausea
Women tend to be more susceptible to UTIs, partly because of the way their bodies are built, says Cheyenne Santiago, R.N., M.S.N., a managing editor at MCG. Men have a longer urethra that runs through the penis and farther away from the anus, so there is less of a chance for bacteria from stool and other sources to make their way to where they can cause problems.
Women, on the other hand, have a very short urethra, says Santiago. So can get bacteria forced up into your bladder.
Sex can also increase the risk of UTIs in women and so Santiago and Dr. Rajan recommend going to the bathroom after intercourse.
Causes Of Urinary Tract Infections
UTIs are usually caused by bacteria from poo entering the urinary tract.
The bacteria enter through the tube that carries pee out of the body .
Women have a shorter urethra than men. This means bacteria are more likely to reach the bladder or kidneys and cause an infection.
Things that increase the risk of bacteria getting into the bladder include:
- having sex
do not use scented soap
do not hold your pee in if you feel the urge to go
do not rush when going for a pee try to fully empty your bladder
do not wear tight, synthetic underwear, such as nylon
do not drink lots of alcoholic drinks, as they may irritate your bladder
do not have lots of sugary food or drinks, as they may encourage bacteria to grow

Can I Become Immune To The Antibiotics Used To Treat A Uti
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.
- Intravenous treatment: In some very complicated cases, where the UTI is resistant to antibiotics or the infection has moved to your kidneys, you may need to be treated in the hospital. The medicine will be given to you directly in your vein . Once youre home, you will be prescribed antibiotics for a period of time to fully get rid of the infection.
