What it is and how it works

Sodium sulfate, potassium sulfate, and magnesium sulfate is a combination osmotic laxative and bowel-cleansing agent, sold under the brand name Suprep Bowel Prep Kit. It is FDA-approved to clean out the colon as preparation for a colonoscopy in adults and in children 12 years and older. A clear, empty colon lets your doctor see the lining clearly during the exam.

It works by pulling water into the bowel, which softens and flushes out the contents. It is taken as a split-dose regimen: you dilute one 6-ounce bottle with water and drink it the evening before your procedure, then drink the second diluted 6-ounce dose the morning of the procedure. Each dose is followed by additional water exactly as directed. Following the water instructions matters, both for a clean prep and to help protect against dehydration.

Cost and savings without insurance

Because a substitutable generic of this bowel prep is available, it is typically the more affordable choice compared with the brand-name Suprep kit. Still, cash prices are not the same everywhere. The same generic prep can cost noticeably more at one pharmacy than at another nearby, which is why comparing before you fill is worth the few minutes. Rx.com checks prices across more than 60,000 pharmacies so you can find a lower cash price in your area.

The maker of brand-name Suprep also runs a manufacturer savings program on its official website, suprepkit.com; those offers usually apply to the brand only and their eligibility and terms vary, so read the fine print. An Rx.com discount coupon is a cash-price tool and is not insurance; use whichever gives you the lower price.

How it compares to other colonoscopy preps

Several colonoscopy prep options are on the market, and the right one depends on your doctor's preference, your kidneys and other health conditions, and how easy the prep is to drink. Your gastroenterologist will usually specify which prep to use.

• Sutab — a tablet-based sulfate prep (swallowed with water) instead of a liquid.
• Suflave — a lower-volume, flavored sulfate/PEG-based prep from the same maker as Suprep.
• Clenpiq — a ready-to-drink, smaller-volume prep.
• Moviprep — a polyethylene glycol (PEG) plus electrolyte prep.
• Polyethylene glycol 3350 — a PEG-based option sometimes used in prep regimens.

Do not switch preps on your own. If cost or tolerability is a concern, ask your provider whether one of these alternatives fits your situation, then compare prices here.

Safety and who should be careful

This prep does not carry a boxed warning, but it can cause serious fluid and electrolyte problems, including low sodium (hyponatremia), low potassium (hypokalemia), and high magnesium (hypermagnesemia). Rare but serious effects have included seizures, heart rhythm changes (arrhythmias), and kidney problems (renal impairment). Drinking all the prescribed water is an important safeguard. Rare reports also include ischemic colitis, aspiration, and allergic reactions.

Use extra caution, and talk with your doctor first, if you have kidney problems, heart failure, a prolonged QT heart rhythm, or take diuretics (water pills), ACE inhibitors, ARBs, or NSAIDs. This prep should not be used if you have a bowel blockage or perforation, toxic colitis or toxic megacolon, gastric retention, or ileus. This is general information, not medical advice; follow your provider's specific instructions and call them with any concerns.
