What a urinary tract infection is
Few infections are more common in women. A UTI begins when bacteria get into the urethra and multiply in the bladder, and the usual culprit is E. coli from the digestive tract. Expect burning or pain when you pee, a frequent and urgent need to go, small amounts each time, pressure low in the pelvis or belly, and urine that looks cloudy or smells strong. A woman's urethra is short, which is why women get these far more often than men. An uncomplicated bladder infection tends to respond fast to a short antibiotic course, usually 3 to 5 days.

How the prescription part works
The secure intake asks about your symptoms, allergies, medications, pregnancy status, past urinary tract infections and the pharmacy you want. A Colorado-licensed physician reads it all and may message you for more detail. When the picture fits an uncomplicated bladder infection and nothing raises a safety concern, that physician can send an electronic prescription to your pharmacy, with same-day pickup in most cases.
Nothing is prescribed automatically at Vyta.co. Your physician may send you for in-person care or testing if your answers point to a kidney infection (fever, chills, back or flank pain), pregnancy, a possible sexually transmitted infection, recurrent UTIs, an unclear diagnosis, a medication allergy or some other complicating factor.

What does Colorado resistance data show?
Bactrim is a first-line choice where local resistance is low, so local numbers count. In a 2022 paper, Denver Health researchers wrote that E. coli resistance to trimethoprim-sulfamethoxazole in their system was above 20 percent, while E. coli stayed 98 percent susceptible to nitrofurantoin in 2018. That is one public health system in Denver, and it can't speak for Grand Junction or Alamosa. For you, it means your Colorado-licensed physician weighs resistance patterns like these alongside your allergies, kidney function, pregnancy status and prior treatment.
Who an online visit suits
Telehealth may suit adult women with the typical signs of an uncomplicated bladder infection: burning when you urinate, going often and urgently, or pressure in the lower belly. It fits especially well if you've had a UTI before and know the pattern.
Sexually transmitted infections and other conditions can feel much the same, so your physician goes through the full intake before deciding if antibiotics are clinically appropriate. Unsure what this is? Use our free UTI symptom checker or read how a UTI differs from BV and a yeast infection.
When you need an exam in person
Some urinary symptoms call for an exam. Get in-person care, even if it means a long drive, when any of these apply.
- Fever, chills, back or flank pain, or nausea and vomiting, which can mean a kidney infection
- Pregnancy, a possible sexually transmitted infection, or a diagnosis that is new or unclear
- UTIs that keep recurring, or symptoms that aren't better within a couple of days on antibiotics

The three first-line antibiotics
Nitrofurantoin (Macrobid), trimethoprim-sulfamethoxazole (Bactrim) and fosfomycin (Monurol) lead the list for an uncomplicated UTI, in line with the IDSA uncomplicated-cystitis guideline and CDC guidance. A typical nitrofurantoin course is 100 mg twice a day for five days. Bactrim is generally one double-strength tablet twice a day for three days where local resistance is low. Fosfomycin is one 3 g dose of granules mixed into water. Your symptoms, allergies, kidney function, pregnancy status and prior treatment guide which drug your physician picks and for how long.
Side effects are usually mild and can include nausea or an upset stomach. Mention a sulfa allergy, because it rules out Bactrim, along with any other antibiotic allergy. Mention kidney problems too: nitrofurantoin is avoided when kidney function is reduced, and also near full-term pregnancy. Keep taking the whole course after you start feeling better.

Why UTIs happen
Bacteria from the bowel or skin usually reach the urethra and climb to the bladder. Sexual activity, a new partner, spermicide or a diaphragm, holding your urine and postmenopausal changes can each raise the risk, and a shorter urethra leaves women more prone. A UTI is not a sexually transmitted infection, and poor hygiene doesn't cause one. Drinking enough and urinating after sex may help lower your risk, although a symptomatic infection usually needs antibiotics once it has taken hold. Separately, CU Boulder's Medical Services says Colorado's dry climate and higher elevation can leave you dehydrated faster than you might expect, and it suggests bringing extra water into the mountains. Read more on what causes UTIs and how to prevent them.
When UTIs keep coming back
Two or more infections in six months, or three or more in a year, usually count as recurrent, and plenty of women land there. If the familiar signs of an uncomplicated bladder infection flare again, a Colorado-licensed physician can often treat that acute episode online the same day. Frequent repeats also deserve a fuller evaluation, possibly a urine culture, a review of risk factors or a preventive (prophylactic) plan, and an in-person primary care clinician or urologist often coordinates that longer workup.
