Sutab Coupons & Prices
Sutab 12 Tablets
Looking for a Sutab coupon before your colonoscopy prep? Sutab (sodium sulfate, magnesium sulfate, and potassium chloride tablets) is a tablet-form bowel-prep option, and Rx.com can show you today's cash price at nearby pharmacies alongside the manufacturer's own savings program, so you can compare before you fill the prescription.
What Sutab is and how the prep works
Sutab is an FDA-approved combination of sodium sulfate, magnesium sulfate, and potassium chloride, taken as tablets rather than a liquid solution, to cleanse the colon before a colonoscopy in adults. It's a brand-name product with no substitutable generic version available.
The regimen is a split dose: 12 tablets (dose 1) taken with 16 ounces of water plus an additional 32 ounces of water, followed by a second set of 12 tablets (dose 2) the day of the procedure, also with the required water. All tablets and water must be finished at least 2 hours before the colonoscopy. Always follow the exact schedule your doctor or the procedure center gives you.
Manufacturer savings card vs. the Rx.com cash coupon
Sutab's manufacturer runs an official savings program at sutab.com, and terms (who qualifies, how much it reduces your cost, and any caps) vary and can change, so check the current details directly on the manufacturer's site. Like most manufacturer copay cards, it's generally intended for people with commercial insurance and typically isn't usable if you're on Medicare, Medicaid, or uninsured.
The Rx.com cash coupon works differently: it's not tied to insurance status at all, so it's an option if you're uninsured, on Medicare, or if the manufacturer's card is declined at the pharmacy counter. Enter your ZIP above to see today's price at pharmacies near you, and compare it against what the manufacturer's card would offer for your situation before you decide which to use.
How Sutab compares to other bowel-prep options
Sutab is one of several products used to prep for a colonoscopy, and doctors choose based on a patient's medical history, kidney function, and personal preference for tablets versus liquid. Other options your doctor may prescribe or recommend include liquid preps like GoLYTELY, Plenvu, and Suprep, the stimulant laxative Dulcolax (sometimes used as part of a prep regimen), and the over-the-counter osmotic laxative MiraLAX, which some prep protocols combine with an electrolyte solution.
None of these options is universally "better" — each has a different volume of liquid required, taste profile, and safety consideration. Your doctor will pick the prep that's appropriate for your health history.
Safety considerations
Sutab carries a risk of fluid and electrolyte abnormalities, including low sodium, low potassium, and dehydration, so drinking the full amount of water required with each dose matters. Your doctor may want to check electrolyte labs before and after the prep, particularly if you have kidney problems, a seizure history, or a heart rhythm condition, and may consider an ECG before and after the procedure in patients at higher cardiac risk.
Sutab should not be used if you have a bowel obstruction or perforation, bowel ileus, toxic colitis or an enlarged colon (megacolon), gastric retention, or a known allergy to its ingredients. It's not a controlled substance. This is general information, not medical advice — talk with your doctor about whether Sutab is right for you, especially if you have kidney disease, ulcerative colitis, or swallowing/aspiration concerns.
