Q: How Long Should You Take Antibiotics for a UTI?

Hello： Please come to the hospital for a urine test, and don't worry. <br>This is Dr. <br>Chang Cheng-yeh, attending physician of the Urology Department at Hsinchu Hospital, Ministry of Health and Welfare.

How many days of medication are required for a urinary tract infection to ensure it is safe?

Recently, I have been feeling strange sensations at the urethral opening, so on March 29, I went to a gynecologist for a urine test, which showed no urinary tract infection (UTI).
However, on March 31, I visited another obstetrician-gynecologist who diagnosed me with a UTI and prescribed a two-week course of medication.
Since I was not very reassured, I went to a urologist on April 2.
The urologist tested me and concluded that I did not have a UTI, suggesting that the four packets of medication I had already taken might have improved my condition, resulting in a negative test.
Nevertheless, the urologist prescribed me two days of Keflex, advising me to finish the previous three days of medication before starting the new prescription.
The urologist also mentioned that I did not need to take medication for two weeks; typically, three to five days of treatment is sufficient for such symptoms.
However, I found conflicting information online stating that a UTI should be treated for one to two weeks to prevent recurrence.

Now, I am unsure whether I should return to the urology clinic after finishing the two days of Keflex or if I should continue taking medication.
As of today, I have completed the medication prescribed on March 31.
I am quite distressed about whether I actually have a UTI, as the test results have been inconsistent.
I do not experience pain or burning during urination, but I do feel a peculiar sensation at the urethral opening, which is somewhat itchy and mildly painful—an indescribable feeling that is just odd.
Additionally, I am unsure if my frequent urination—about once an hour—could be considered polyuria, as I have been drinking a considerable amount of water.
Thank you, doctor, for your patience in reading this.

When it comes to the appropriate duration for taking antibiotics for a urinary tract infection (UTI), the answer can vary based on individual circumstances, the severity of the infection, and the specific antibiotic prescribed. Generally, for uncomplicated UTIs, a typical course of antibiotics may last anywhere from 3 to 7 days. However, some guidelines suggest that in certain cases, especially for recurrent infections or more complicated cases, a longer course of treatment (up to 14 days) may be necessary.

In your situation, it seems that you have received conflicting information from different healthcare providers regarding your diagnosis and treatment. Initially, you were told that you did not have a UTI, and then later diagnosed with one, only to be told again that you might not have it after all. This inconsistency can understandably lead to confusion and concern about whether you should continue taking antibiotics.

It's important to note that antibiotics are effective against bacterial infections, and their use should be guided by a confirmed diagnosis. If your symptoms have improved after taking the initial course of antibiotics, it may indicate that you were indeed experiencing a UTI or a similar infection. However, if you are still experiencing discomfort or unusual sensations in the urethra, it may be worth discussing this further with your healthcare provider.

Regarding the duration of treatment, if your urologist has advised that a 3 to 5-day course of Keflex (cephalexin) is sufficient for your symptoms, it is likely based on their clinical judgment and your specific case. It is essential to follow your doctor's advice, especially if they have assessed your condition and determined that a shorter course is appropriate.
If you complete the prescribed course of Keflex and still experience symptoms, or if you have any concerns about your urinary health, it would be advisable to return to your urologist for further evaluation. They may want to conduct additional tests, such as a urine culture, to determine if there is an underlying issue that needs to be addressed.

As for your concern about frequent urination, this can be influenced by several factors, including increased fluid intake, anxiety, or even irritative conditions of the bladder or urethra. If you find that you are urinating more frequently than usual, and it is accompanied by discomfort or other symptoms, it is worth discussing this with your healthcare provider as well.

In summary, while the general recommendation for treating uncomplicated UTIs is often around 3 to 7 days, your specific treatment should be guided by your healthcare provider's assessment. If symptoms persist after completing your medication, or if you have ongoing concerns, do not hesitate to seek further medical advice. Your health and comfort are paramount, and clear communication with your healthcare team is key to managing your condition effectively.
