How to Find a Doctor Who Can Prescribe Pentasa XR Near You [2026 Guide]

Pentasa XR (mesalamine extended-release) is a prescription medication — you'll need a licensed healthcare provider to write your prescription. The good news is that Pentasa XR is not a controlled substance, meaning it doesn't require any special DEA registration or prescribing restrictions. A wide range of providers can prescribe it. Here's how to find the right one for your situation.

Which Doctors Can Prescribe Pentasa XR?

Because Pentasa XR is not a controlled substance, it can be prescribed by any licensed healthcare provider with prescribing authority. The most common prescribers include:

• Gastroenterologists (GI specialists): The most common prescribers for Pentasa XR. They specialize in digestive diseases including ulcerative colitis and Crohn's disease and are best positioned to determine the right mesalamine formulation for your specific GI anatomy and disease severity.
• Primary care physicians (PCPs) and internists: Many primary care doctors manage mild-to-moderate UC, especially for patients who have already been diagnosed and are in stable remission.
• Nurse practitioners (NPs) and physician assistants (PAs): NPs and PAs with prescribing authority in their state can prescribe Pentasa XR, often working within a gastroenterology or primary care practice.
• Colorectal surgeons: May prescribe mesalamine for patients with IBD managed through surgical care.

Do I Need a Specialist, or Can My PCP Prescribe Pentasa XR?

It depends on your situation. If you've already been diagnosed with ulcerative colitis, are in stable remission, and have a well-established treatment plan, your primary care physician can often manage refills and routine adjustments to your Pentasa XR prescription without needing a GI specialist for every visit.

However, if you're newly diagnosed, having frequent flares, or considering a change in treatment — including switching mesalamine formulations — a gastroenterologist is the appropriate specialist to consult. GI specialists have deep expertise in calibrating mesalamine therapy to your specific disease pattern.

How to Find a Gastroenterologist Near You

To find a gastroenterologist who can diagnose and treat your condition and prescribe Pentasa XR:

1. Your insurance directory: Log into your insurance plan's member portal and search for in-network gastroenterologists in your zip code.
2. Zocdoc or similar platforms: Search for gastroenterologists accepting new patients with your insurance. You can filter by next available appointment.
3. Referral from your PCP: Ask your primary care physician for a referral to a gastroenterologist they trust. This is often the fastest path to a new GI appointment and may be required by your insurance.
4. The Crohn's & Colitis Foundation: Their website (crohnscolitisfoundation.org) provides a provider finder tool specifically for GI specialists experienced with IBD.

Can I Get Pentasa XR Through Telehealth?

Yes — for many patients, telehealth is a convenient and fast option for getting a Pentasa XR prescription, especially for routine refills and medication management. Because Pentasa XR is not a controlled substance, there are no restrictions on prescribing it via telehealth in any U.S. state.

Telehealth options for Pentasa XR include:

• Virtual gastroenterology practices: Many gastroenterology groups now offer telehealth appointments for established and new patients.
• General telehealth platforms: Teladoc, MDLive, and similar services can often prescribe Pentasa XR for patients with an established UC diagnosis.
• Your existing doctor via telehealth: If you're an established patient, ask your current gastroenterologist or PCP about telehealth appointments for prescription refills — this is the simplest path and avoids a new patient intake process.
