Burning while passing urine, going to the bathroom again and again, or a constant urge even when little urine passes. Most people in Bangalore recognise these as UTI symptoms and the first reaction is simple: “Which tablet should I take?”
Medicines do play an important role in treating urinary tract infections. But what many patients do not realise is this: the right medicine depends on where the infection is, how severe it is, and why it started in the first place. This is exactly why UTIs often keep coming back even after taking tablets.
This blog explains which medicines are commonly used for UTI, when they actually help, and when it is safer to see a doctor instead of continuing tablets on your own.
Why urinary tract infections happen
A urinary tract infection occurs when bacteria enter the urinary system and start multiplying. In most cases, the infection starts in the bladder. In some people, it can move upward and affect the kidneys, which is more serious.
Common reasons UTIs develop include:
- Inadequate water intake
- Delaying urination
- Poor bladder emptying
- Diabetes
- Hormonal changes
- Prostate enlargement in men
- Recurrent infections without proper testing
Because the cause differs from person to person, the same tablet does not work for everyone.
Common medicines used for UTI and how they work
Doctors prescribe UTI medicines after considering symptoms, urine test results, age, and medical history. Some commonly used antibiotic salts include:
Nitrofurantoin
This medicine is frequently prescribed for simple bladder infections. It works well when bacteria are sensitive to it. However, it is not suitable for everyone, especially people with certain kidney conditions.
Fosfomycin
Often given as a single dose in selected cases, mainly for uncomplicated UTIs in women. It is convenient, but not meant for repeated infections or severe symptoms.
Trimethoprim–Sulfamethoxazole
Used in some patients when bacterial resistance levels are low. It must be taken for the full duration to prevent recurrence.
Cephalosporins and Fluoroquinolones
These are reserved for more severe infections, recurrent UTIs, or infections involving the kidneys. They are prescribed carefully because of side effects and resistance concerns.
Pain-relief tablets may reduce burning or discomfort, but they do not treat the infection itself.
When UTI medicines usually work well
Tablets are likely to help when:
- Symptoms are mild and started recently
- Infection is limited to the bladder
- The correct antibiotic is chosen
- The full course is completed as advised
In such cases, improvement is usually seen within two to three days.

Why symptoms come back even after taking tablets
This is one of the most common problems doctors see.
UTI medicines may not solve the issue if:
- Antibiotics were taken without urine testing
- Treatment was stopped once symptoms reduced
- There is an underlying cause like stones, diabetes, or prostate problems
- The infection has reached the kidneys
- The bacteria are resistant to the medicine used
In these situations, tablets may temporarily reduce symptoms, but the infection continues silently.
Warning signs that need medical attention
Do not ignore UTI symptoms if you notice:
- Fever or chills
- Pain in the lower back or sides
- Blood in urine
- Burning that does not improve after two to three days of tablets
- Repeated UTIs in a short time
These signs suggest a more complicated infection that needs proper evaluation.
