How Do Antibiotics Treat A Uti
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.
The Rise Of Drug Resistant Utis
Each year, millions of Americans contract UTIs, and most of those patients are women.
In the past, UTIs have been cured “easily and quickly” through a short course of antibiotics, but that’s increasingly not the case, according to Richtel.
The New York City Department of Health, for instance, recently found “sharp rises in resistance to gold standard treatments over the past decade and a half,” Richtel writes. Specifically, the department found that one-third of the most common type of UTIuncomplicated UTIs caused by E.coliare resistant to Bactrim, one of the most commonly used treatments, and about one-fifth are resistant to five other common drug treatments.
According to Richtel, physicians across the United States have stopped prescribing the drug ampicillin, which was once the most popular way to treat the infections, altogether because UTIs grew resistant to it. Now, some UTIs requiring intravenous antibiotics to clear.
How Often Are Utis Resistant
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.

Bactrim Septra For Utis In Multiple Sclerosis
Bactrim and Septra are antibiotics used in multiple sclerosis for urinary tract infections treatment and prevention.1
Bactrim treats different types of infection caused by bacteria. Due to their established effectiveness, low cost, and relative lack of toxicity, this group of antibiotics remains a first choice drug for conventional treatment of acute, uncomplicated urinary tract infections caused by susceptible organisms.
The recommended oral dose of Bactrim for mild to moderate infections is 2 grams initially, followed by 1 gram twice daily. For severe infections, the recommended dose is 2 grams initially, followed by 1 gram three times a day.
These types of medications must be used for the full prescribed length of time, even if the symptoms improve before the infection has completely cleared.
Common Bactrim side effects include nausea, vomiting, loss of appetite, and mild itching or rash.
There are generics available rather than the brand-name drugs.
Antibiotic Warnings And Treatment Concerns
The most commonly prescribed antibiotics for uncomplicated UTIs are similar in efficacy. But its important to note that ampicillin, amoxicillin, and sulfonamides are no longer the drugs of choice for combatting UTIs because of the emergence of antibiotic resistance. In addition, amoxicillin and clavulanate has been shown in previous research to be significantly less effective than others when it comes to treating urinary tract infections.
Also, as noted above, the FDA advises against using fluoroquinolones for uncomplicated UTIs. These medicines should only be considered if no other treatment options are available. In some cases, such as a complicated UTI or kidney infection, a healthcare provider may decide that a fluoroquinolone medicine is the best option, notes the American Academy of Family Physicians.
For pregnant women, some common antibiotics, such as fluoroquinolones and tetracyclines, should not be prescribed because of possible toxic effects on the fetus. But oral nitrofurantoin and cephalexin are considered good antibiotic choices for pregnant women with asymptomatic bacteriuria and acute cystitis, according to past research.

Carefully Targeted Antibiotic Treatment For Urinary Tract Infections
So what do we do now? As a society and as individuals, we should reduce and carefully target antibiotic use. Both physicians and patients should be aware of the grave potential to lose effective antibiotics for all infections even simple UTIs. Its an opportunity that empowers individuals to have informed conversations with their doctors. Every time your doctor prescribes an antibiotic, ask: Do I need this? Why? Is there an antibiotic-free alternative? Talking about it might be enough to meaningfully reduce inappropriate antibiotic use.
If youre having UTI symptoms like burning with urination, more frequent urination, bloody or cloudy urine, low abdominal pain, or fever, you should see a medical provider to get tested. Youll have to urinate into a container and the medical office will test for products of bacterial metabolism. Make sure to tell your provider if youve had UTIs before, and what antibiotic you took. If you have a history of antibiotic-resistant infections, share that, too. There are alternatives to Cipro and Bactrim, but antibiotic choices are limited.
If antibiotic resistance continues to grow, more people will need intravenous treatment for UTIs we used to cure with simple oral antibiotic courses. Were also likely to see more complications, like kidney infections and sepsis, arising from ineffective treatment.
Clostridioides Difficile Associated Diarrhea
Clostridioides difficile associated diarrhea has been reported with use of nearly all antibacterial agents, including Bactrim, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Antibiotics Used For Complicated Utis
Before getting into how to best treat a complicated UTI, its important to understand which UTIs are considered complicated. Here are some guidelines:
- Urinary tract abnormalities are present
- Youre pregnant
- The patient is a child
- A comorbidity is present that increases risk of infection or treatment resistance, such as poorly controlled diabetes
- 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:

For a complicated infection, you might need to take antibiotics for 14 days or more.
If you still have symptoms after completing antibiotics, a follow-up urine test can show whether the germs are gone. If you still have an infection, you’ll need to take antibiotics for a longer period of time.
If you get UTIs often, you may need a prolonged course of antibiotics. And if sex causes your UTIs, you’ll take a dose of the medicine right before you have sex. You can also take antibiotics whenever you get a new UTI if youâre having symptoms and a positive urine culture.

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.
