What is a UTI, exactly?
A urinary tract infection (UTI) ranks among the most common infections women get. Bacteria, most often E. coli from the digestive tract, enter the urethra and multiply in the bladder. Then come the familiar signs: burning or pain when you pee, frequent and urgent trips that produce very little, pressure in the pelvis or lower belly, and urine that turns cloudy or strong-smelling. Women have a shorter urethra, which is the reason they get UTIs far more often than men do. Most uncomplicated bladder infections respond quickly to an antibiotic course of 3 to 5 days.

How the online prescription works
The secure assessment asks about your symptoms, allergies, current medications, pregnancy status and past urinary tract infections, plus which pharmacy you prefer. An Arizona-licensed physician reviews all of it and may message you for more detail. If this looks like an uncomplicated bladder infection and there are no safety concerns, an electronic prescription can go to your pharmacy, usually for pickup that same day.
Antibiotics are never automatic at Vyta.co. Your physician may steer you to testing or an in-person visit if you report fever, chills, or back or flank pain, which suggest a kidney infection. The same goes for pregnancy, a possible sexually transmitted infection, recurrent UTIs, an unclear diagnosis, a medication allergy or any other complicating factor.

Does Arizona's heat raise the odds of a UTI?
Phoenix summers make women ask, and the honest answer is that nobody has proven it. A 2018 study in Epidemiology and Infection looked at hospital admissions around the country from 1998 to 2011. Months averaging 27.5 to 30 C, about 82 to 86 F, carried about 20 percent higher odds of a UTI admission than months averaging 5 to 7.5 C, about 41 to 46 F. Above 30 C the odds fell again. The authors raised fluid loss as a possible reason and did not claim the heat is the cause. Staying hydrated may help. In a 2018 JAMA Internal Medicine trial, premenopausal women with three or more bladder infections in the prior year, who drank under 1.5 liters of fluid a day, added 1.5 liters of water daily and had about half as many infections over the next year as women who made no change. That result covers that group only. Once burning or urgency has started, antibiotics are usually what you need, and your physician decides which one.
Who online UTI care fits
Online care may be appropriate if you are an adult woman with typical symptoms of an uncomplicated bladder infection: it burns when you urinate, you go often and urgently, or your lower belly feels full of pressure. Recognizing the pattern from an earlier UTI makes it an especially good fit.
The same complaints can come from a sexually transmitted infection or another condition, so your physician weighs your whole intake before settling on antibiotics. Not sure what this is? Our free UTI symptom checker is a good first stop, and you can also read how a UTI differs from BV and a yeast infection.
When to get seen in person
Some urinary symptoms need hands-on care. Go in person when any of these apply.
- Fever, chills, back or flank pain, or nausea and vomiting, which can point to a kidney infection
- You are pregnant, you may have a sexually transmitted infection, or the diagnosis is new or unclear
- UTIs that keep recurring, or symptoms no better a couple of days into antibiotics

The first-line antibiotics
For an uncomplicated UTI, three drugs come up most: nitrofurantoin (Macrobid), trimethoprim-sulfamethoxazole (Bactrim) and fosfomycin (Monurol). Physicians commonly weigh them in line with the IDSA uncomplicated-cystitis guideline and guidance from the CDC. Nitrofurantoin typically runs 100 mg twice daily for five days. Bactrim, where local resistance is low, is usually one double-strength tablet twice daily for three days. Fosfomycin is a single 3 g dose of granules you stir into water. Which one you get, and for how long, depends on your symptoms, allergies, kidney function, pregnancy status and prior treatment.
Side effects tend to be mild, with nausea or stomach upset the most common. Your physician needs to hear about any sulfa allergy, which rules out Bactrim, any other antibiotic allergy, and any kidney problems, since nitrofurantoin is avoided when kidney function is reduced or near full-term pregnancy. Finish the full course, even once the burning stops. See our full guide to UTI antibiotics and treatment →
Why UTIs happen
It usually begins with bacteria from the bowel or skin that reach the urethra and move up into the bladder. Sex, a new partner, spermicide, a diaphragm, holding your urine and postmenopausal changes can all raise the risk. Anatomy plays a part too, since a shorter urethra leaves women more prone. UTIs are not an STI. They are also not caused by poor hygiene. Drinking enough water and urinating after sex may help reduce risk, but a symptomatic infection that is established usually needs antibiotics. Learn more about 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, is the usual line for calling UTIs recurrent, and you are far from alone if you have crossed it. A flare with your usual uncomplicated bladder symptoms can often be treated online the same day by an Arizona-licensed physician. Repeat infections still need a wider look, such as a urine culture, a check of your risk factors or a preventive (prophylactic) plan, and that workup is often coordinated in person with a primary care clinician or urologist here in Arizona.
