What is urinary tract infection?
A urinary tract infection (UTI) is a bacterial infection anywhere in the urinary system — most commonly in the bladder (cystitis), but sometimes in the urethra (urethritis) or, more seriously, the kidneys (pyelonephritis).
UTIs are extremely common: about half of women will have at least one in their lifetime, and roughly 10% of women have a UTI every year. They can affect men too, but less frequently — and when they do, they're more likely to be complicated.
Most UTIs are caused by bacteria from the GI tract — usually E. coli — getting into the urethra and traveling up into the bladder. Sexual activity, certain forms of birth control (especially diaphragms and spermicide), menopause-related changes, and dehydration all raise the risk.
Do I have urinary tract infection? Common signs
If most of these describe what you're experiencing, telehealth is a reasonable next step:
What causes it
The vast majority of uncomplicated UTIs are caused by Escherichia coli (E. coli) from the GI tract. Less commonly, other bacteria like Klebsiella, Proteus, Staphylococcus saprophyticus, or Enterococcus are responsible. Risk factors include sexual activity, holding urine for long periods, diaphragm or spermicide use, menopause (lower estrogen thins the urethral lining), pregnancy, diabetes, kidney stones, and any structural abnormality of the urinary tract.
Is it contagious?
UTIs themselves are not contagious — you don't catch a UTI from someone else. The bacteria are usually your own. Sexual activity can introduce bacteria from the perineal area into the urethra, which is why some women get UTIs after sex, but this is mechanical rather than infectious transmission.
About half of women will have a UTI in their lifetime — and the right antibiotic usually brings real relief within a day.
Can it be treated online?
Uncomplicated UTIs in non-pregnant adult women with classic symptoms and no complicating factors are well-suited to telehealth. A clinician asks about your symptoms, history, any red flags, and recent treatments, then prescribes a short course of antibiotics that targets the most likely organisms.
Telehealth is NOT appropriate for: men (UTIs in men are more likely complicated and warrant in-person evaluation), pregnant patients, anyone with fever or back/flank pain (possible kidney involvement), recurrent UTIs (>2 in 6 months), recent hospitalization, structural urinary issues, or symptoms not classic for cystitis.
How urinary tract infection is treated
Standard first-line treatments for uncomplicated UTIs include nitrofurantoin (Macrobid, 5 days), trimethoprim-sulfamethoxazole (Bactrim, 3 days) where local resistance allows, and fosfomycin (single dose) in some cases. Symptoms typically improve within 24–48 hours. Pain relief while waiting for antibiotics to work can include phenazopyridine (AZO, OTC) — note this turns urine orange/red, that's normal. Drinking plenty of water helps flush bacteria out.
Self-care while you wait
- Drink plenty of water — aim for 6–8 glasses a day while symptomatic
- Don't hold urine — empty your bladder as soon as you feel the urge
- Pee after sexual activity to flush the urethra
- Wipe front to back
- Cranberry juice or supplements may help prevent recurrence (modest evidence)
- A heating pad on the lower belly can relieve cramping
How long does it last?
With antibiotics, symptoms usually start improving within 24 hours and clear within 2–3 days. Most prescriptions run 3–5 days total. Without treatment, an uncomplicated UTI might resolve on its own, but it can also progress to a kidney infection — not worth the risk.
Frequently asked questions
Can I get a UTI antibiotic online without a urine test?
Yes — for uncomplicated cases in adult women with classic symptoms and no red flags, current guidelines support empiric treatment based on symptoms alone. Clinicians follow specific criteria to decide if your case qualifies.
How soon will I feel better?
Most people feel significantly better within 24–48 hours of starting the right antibiotic. If you're not improving by day 2–3, the bacteria may be resistant and a culture is needed.
Can men get treated for UTIs through telehealth?
UTIs in men are uncommon and almost always considered "complicated" — they need in-person evaluation, urine culture, and sometimes imaging. Telehealth isn't the right path for men with UTI symptoms.
What if I keep getting UTIs?
Two or more UTIs in 6 months counts as recurrent and warrants in-person workup — possible causes include incomplete emptying, low estrogen, kidney stones, or biofilm-producing bacteria. Long-term low-dose antibiotic prophylaxis or vaginal estrogen may be options.
Is this just bladder irritation or a real infection?
Symptoms can overlap with bladder irritation from diet, sexual activity, or menopause-related changes. Burning pain on urination plus urgency, especially with cloudy or bloody urine, points more strongly to infection. If you're unsure, get evaluated — over-treating without infection drives antibiotic resistance.
