Causes Of Urinary Tract Infections
Urinary tract infections 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:
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 You Get Rid Of A Uti Naturally At Home Or Do You Need Antibiotics
Sometimes, you can get rid of a UTI naturally by resting, drinking lots of water, taking dietary supplements, and giving the infection some time to heal. Research from 2017 suggests that somewhere between 25% and 42% of UTIs resolve naturally without the use of antibiotics.
However, there are certain situations where wait and see just isnt an acceptable approach. Untreated UTIs can cause potentially life threatening complications, including .
What Happens When A Uti Goes Untreated
Thanks to early diagnosis and proper treatment, the vast majority of lower urinary tract infections result in no complications. However, if left untreated, a UTI can have serious ramifications notes the Mayo Clinic, including:
- Premature birth and low birth weight
- Kidney damage, which can occur is an untreated UTI spreads from the bladder to the kidneys.

If You Forget To Take It
If you forget to take a dose, take it as soon as you remember, unless its nearly time for your next dose. In this case, just leave out the missed dose and take your next dose at the usual time.
Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to remember your medicines.

Urinary Tract Infection Antibiotics
Antibiotics are the treatment of choice for a urinary tract infection.
Your veterinarian will perform a sensitivity test to see how the bacteria in the urine react to certain drugs, then check if your dog is allergic to any drugs and then prescribe the proper antibiotics.
If the right antibiotic is prescribed, the number of bacteria in the dogs urine will decrease.
However, your veterinarian may prescribe the antibiotic without performing the urine culture test.
A urinary tract infection is often treated with antimicrobials.
These are usually taken for 2 to 3 weeks, depending on how much the infection has spread.
The most common antibiotics and antimicrobials are:
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

Blisters And Other Skin Problems
Blisters are small, raised lesions where fluid has collected under the skin. They may be caused by an allergic reaction, burns, frostbite, or by excessive friction or trauma to the skin. Blisters may also be a symptom of a systemic illness, or of a specific skin disorder.
This side effect is somewhat rare, but serious when it does occur. If you experience discoloration, blistering, or peeling or loosening of the skin after taking amoxicillin, contact your doctor right away.
Home treatments may be used to manage mild, non-itching rashes that are not severe. Treatment includes antihistamines or hydrocortisone, oatmeal baths, and drinking lots of water. If skin starts blistering, peeling, or loosening, however, seek medical attention immediately.
To prevent severe skin irritations, do not take amoxicillin if youre allergic to penicillin.
Possible Side Effects Of Amoxicillin
Like many antibiotics, amoxicillin-clavulanate potassium may cause some common side effects.
These newer drugs are not associated with antibiotic resistance yet.
However, they are used more sparingly to prevent the development of multi-drug resistance.
Our physicians can prescribe antibiotics for various conditions, but only if necessary. Chat with a provider to see which treatment option is best for you.

How Is A Uti Diagnosed
To diagnose a UTI, your GP will examine you and ask you questions about your general health. Sometimes that might be enough to diagnose a UTI. Your doctor may want you to provide a urine sample to identify what bacteria is causing the infection. Your doctor may also do a blood test and check your temperature and heart rate.

Urine Drug Concentration & 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.

Dosage Regimens For Uti:
Currently, the duration of therapy for UTI is controversial. Although animals are routinely treated with antimicrobial drugs for 1014 days, shorter duration antimicrobial regimens are routinely prescribed in human patients, including single-dose fluoroquinolone therapy. A clinical comparison of 3 days of therapy with a once-daily high dose of enrofloxacin with 2 wk of twice daily amoxicillin-clavulanic acid showed equivalence in the treatment of simple UTI in dogs. However, further studies are needed to determine the optimal dosage regimens for different classes of antimicrobials, and it is inappropriate to use fluoroquinolones as first-line therapy for simple UTIs. Animals with complicated UTI may require longer courses of therapy, and underlying pathology must be addressed. Chronic complicated cases of UTI, pyelonephritis, and prostatitis may require antimicrobial treatment for 46 wk, with the risk of selecting for antimicrobial resistance. A follow-up urine culture should be performed after 47 days of therapy to determine efficacy. If the same or a different pathogen is seen, then an alternative therapy should be chosen and the culture repeated again after 47 days. Urine should also be cultured 710 days after completing antimicrobial therapy to determine whether the UTI has resolved or recurred.

Since UTI symptoms usually improve just a few days after starting antibiotics, youll want to talk to your healthcare provider if you notice that UTI symptoms are still hanging around after finishing your antibiotics.
Theres no need to panic, but you and your healthcare provider will want to make sure the antibiotics actually worked against your UTI. To do this, they may take another sample of your urine to see if the bacteria are still there or not. If the infection is cured, youll want to be sure there isnt a different issue thats causing similar symptoms.
