How to Find a Doctor Who Can Prescribe Urocit-K XR Near You [2026 Guide]

If you've been told you need potassium citrate to prevent kidney stones — or if you've been diagnosed with renal tubular acidosis or uric acid lithiasis — you may be wondering which type of doctor prescribes Urocit-K XR and how to find one near you. The good news: Urocit-K XR is not a controlled substance, so it can be prescribed by a wide range of providers, including via telehealth.

Who Can Prescribe Urocit-K XR?

Because potassium citrate extended release is not a controlled substance, it can be prescribed by any licensed prescriber in the United States. That includes:

Urologists: The most common prescribers for kidney stone prevention. A urologist is typically the first specialist to recommend potassium citrate after a stone event.

Nephrologists: Kidney disease specialists who manage renal tubular acidosis and complex stone disease, often using Urocit-K XR as part of a long-term treatment plan.

Primary care physicians (PCPs): Can prescribe potassium citrate for patients with documented stone history and known metabolic abnormalities. Many PCPs handle refills once a specialist has established the diagnosis and dosing.

Nurse practitioners (NPs) and physician assistants (PAs): Can prescribe Urocit-K XR in most states, often working within urology or nephrology practices.

Do You Need a Specialist to Get Urocit-K XR?

Not necessarily. If you have a documented history of kidney stones with known hypocitraturia (low urinary citrate), your PCP can often prescribe potassium citrate ER based on your prior workup. However, the AUA recommends a 24-hour urine metabolic evaluation for all first-time stone formers and all recurrent stone formers, which typically requires a urologist or nephrologist to order and interpret. If you haven't had this workup yet, you should see a specialist before starting potassium citrate therapy — the right medication depends on your specific urine chemistry.

How to Find a Urologist or Nephrologist Near You

Your insurance directory: Search your insurer's online provider directory for in-network urologists or nephrologists by ZIP code. Filter by specialty (urology or nephrology) and check for availability.

Zocdoc.com: Shows real-time appointment availability for urologists and nephrologists near you, with insurance filter options.

Your PCP: Ask for a referral to a urologist. A PCP referral can sometimes get you a faster appointment and ensures the specialist receives your medical records.

Can You Get a Urocit-K XR Prescription via Telehealth?

Yes. Because potassium citrate extended release is not a controlled substance, there are no legal restrictions on telehealth prescribing. A telehealth provider can review your prior lab results (24-hour urine metabolic panel, serum electrolytes, creatinine) and prescribe Urocit-K XR if clinically appropriate. This is especially useful if you need a refill, are managing an established diagnosis, or are in a rural area with limited specialist access.

For a first-time prescription or new diagnosis, a physical exam and lab workup are typically still recommended before starting therapy. However, if you've already had the workup and just need a prescription filled, telehealth is a fast and convenient option.

What to Bring to Your Appointment

Any prior 24-hour urine test results (citrate, calcium, oxalate, uric acid, pH, volume)

Imaging reports if you've had a CT scan or ultrasound showing kidney stones

Stone analysis results if you've passed or had a stone removed

A list of current medications (to check for drug interactions with potassium citrate)

Recent blood work: serum creatinine, serum potassium, and basic metabolic panel
