Need a doctor who prescribes Ibsrela for IBS-C? Learn which specialists prescribe it, how to find one near you, and what to expect at your first visit.
If you've been dealing with irritable bowel syndrome with constipation (IBS-C) and think Ibsrela (Tenapanor) might be right for you, the first step is finding a doctor who can prescribe it. Ibsrela is a prescription medication — you can't get it over the counter — so you'll need a provider who understands IBS-C treatment options and is familiar with this medication.
This guide walks you through exactly how to find a prescribing doctor near you, what to expect at your appointment, and how to move forward once you have a prescription in hand.
Ibsrela can be prescribed by several types of healthcare providers:
In most cases, a gastroenterologist will be the most experienced with Ibsrela specifically. However, any licensed physician or qualified provider can write the prescription.
If you have health insurance, start by searching your plan's provider directory. Most insurance companies have an online "Find a Doctor" tool where you can search by specialty (gastroenterology) and location. This ensures the provider you see is in-network, which can significantly reduce your out-of-pocket costs.
Websites like Zocdoc and Healthgrades let you search for gastroenterologists and other specialists near you. You can filter by insurance accepted, availability, and patient reviews. Many providers on these platforms offer online booking, so you can schedule an appointment right away.
If you already see a primary care doctor, ask for a referral to a gastroenterologist. Your doctor likely has trusted colleagues they refer IBS patients to regularly. Some insurance plans (especially HMOs) require a referral before you can see a specialist, so this step may be necessary anyway.
Telehealth is a convenient option for getting an Ibsrela prescription, especially if you live in a rural area or have a busy schedule. Many gastroenterologists and primary care providers now offer virtual visits where they can evaluate your symptoms and prescribe medication. Since Ibsrela is not a controlled substance, it can be prescribed during a telehealth appointment in most states.
Whether you're seeing a doctor in person or via telehealth, here's what to prepare for:
Once your doctor prescribes Ibsrela, the next step is filling it. Here are a few things to keep in mind:
Ibsrela is a specialty brand-name medication made by a single manufacturer (Ardelyx). Not every pharmacy keeps it on the shelf. You may need to check a few locations or use a tool like Medfinder to find a pharmacy that has Ibsrela in stock near you.
Most insurance plans require prior authorization for Ibsrela. This means your doctor's office will need to submit paperwork to your insurance company explaining why Ibsrela is medically necessary. This process can take a few days to a couple of weeks, so be patient. Your doctor's office should handle most of this for you.
Ibsrela comes as a 50 mg tablet taken twice daily — once before breakfast and once before dinner. Your doctor will explain the dosing instructions, but you can also read more in our complete guide to Ibsrela uses and dosage.
Before you start taking Ibsrela, make sure you understand the potential side effects. The most common is diarrhea (affects about 16% of patients), which makes sense given the medication's mechanism. Your doctor should review when to call their office if side effects become concerning.
Finding a doctor who can prescribe Ibsrela doesn't have to be complicated. Start with your primary care provider or use your insurance directory to find a gastroenterologist near you. Telehealth is also a solid option if you want a faster, more convenient route.
The most important thing is to come prepared — know your symptom history, what you've tried before, and any questions about cost. With the right provider, you can work together to figure out if Ibsrela is the right fit for managing your IBS-C symptoms.
