What is a UTI?
A urinary tract infection occurs when bacteria — most commonly E. coli (80–85% of cases) from the gut — enter and multiply in the urinary tract. Cystitis is infection of the bladder (lower UTI), the most common type. Pyelonephritis is infection of the kidneys (upper UTI), more serious and requiring different treatment. In women, the short urethra and its proximity to the anus make ascending infection much more likely than in men — which is why UTIs are far more common in women. In men, UTIs are less common but more likely to have an anatomical cause and generally require more thorough investigation.
Risk factors include: female anatomy, sexual activity, incomplete bladder emptying, urinary catheters, kidney stones, diabetes, immunosuppression, and menopause (reduced protective vaginal flora). Uncomplicated cystitis in a healthy, non-pregnant woman is the most common scenario — readily treatable with a short course of antibiotics based on symptoms alone, without always requiring prior urine culture.
Key facts
- ✓Classic UTI symptoms are highly specific — a doctor can prescribe empirically based on symptoms alone in uncomplicated cases
- ✓Fever, chills, and flank pain suggest kidney involvement (pyelonephritis) — more serious, requires longer treatment
- ✓Completing the full antibiotic course matters — stopping early when symptoms improve contributes to resistance
- ✓Frequent recurrent UTIs (3+ per year) require evaluation for underlying cause and may benefit from prophylaxis
- ✓Drinking more water and urinating after sex reduce UTI risk but do not replace antibiotic treatment when infection is present

Consult now →Symptoms: cystitis vs. pyelonephritis
Cystitis (bladder infection): Dysuria (burning or pain when urinating), urinary frequency (needing to urinate often but passing little), urgency, suprapubic pressure or discomfort, cloudy or strong-smelling urine, and sometimes blood in the urine. No fever or systemic symptoms. Pyelonephritis (kidney infection): All or some of the above, plus fever (typically above 38.5°C), chills, flank or back pain, nausea, and vomiting. Pyelonephritis requires a longer antibiotic course (7–14 days) and sometimes intravenous antibiotics if severe.
If symptoms are limited to the lower urinary tract in an otherwise healthy adult woman — not pregnant, no diabetes, no urological abnormalities — this is uncomplicated cystitis treatable empirically. If fever, flank pain, vomiting, or significant systemic symptoms are present, a urine culture should be obtained and more aggressive treatment initiated.

Book nowAntibiotic treatment
First-line antibiotics for uncomplicated cystitis in Peru: nitrofurantoin 100 mg twice daily for 5 days (preferred — good efficacy, low resistance, minimal systemic effects); fosfomycin 3g single dose (extremely convenient, available at most pharmacies); trimethoprim-sulfamethoxazole (TMP-SMX) 960 mg twice daily for 3 days — however, local resistance rates in Peru are relatively high, making this a secondary option. Fluoroquinolones (ciprofloxacin) are effective but should not be used first-line for uncomplicated UTIs due to resistance concerns.
Phenazopyridine (bladder analgesic) can relieve burning and urgency within hours while antibiotics take effect — available without prescription in Peru but should be used for 1–2 days only as it does not treat the infection. Symptoms typically improve within 24–48 hours of starting antibiotics; if they don't, a urine culture to check for resistant bacteria is appropriate.
FAQ
Can I treat a UTI without antibiotics?
Uncomplicated cystitis can occasionally resolve on its own, but antibiotics significantly shorten duration, prevent spread to kidneys, and reduce recurrence risk. Without treatment, a small percentage of bladder infections ascend to pyelonephritis — more serious and harder to treat. Antibiotics are strongly recommended.
Does cranberry juice prevent or treat UTIs?
Cranberry products (especially concentrated supplements, not sugary juice cocktails) have modest evidence for reducing UTI recurrence — possibly by reducing bacterial adherence to the bladder wall. They are not a treatment for an active infection. For women with frequent recurrent UTIs, cranberry supplements may be a useful adjunct.
I keep getting UTIs — what can I do?
Recurrent UTIs (3+ per year) should be evaluated by a physician. Strategies include: post-coital antibiotic prophylaxis, continuous low-dose prophylaxis, cranberry supplements, vaginal estrogen in postmenopausal women, and investigation for urological causes. An online physician can initiate this evaluation and management plan.
Can an online doctor prescribe UTI antibiotics in Peru?
Yes. A Delvir physician can evaluate your symptoms and prescribe the appropriate antibiotic with a digital prescription valid at pharmacies throughout Peru — Inkafarma, MiFarma, Boticas y Salud, and others. No in-person visit required for uncomplicated cases.
