Head-to-head comparisons of medication uses, side effects, warnings, and more.
Suprep (sodium sulfate/potassium sulfate/magnesium sulfate) and Miralax (polyethylene glycol 3350) are both osmotic laxatives, but they are used for different purposes. Suprep is a prescription medication used to clean out your colon before a colonoscopy, while Miralax is an over-the-counter medication for occasional constipation. Suprep requires a two-dose regimen taken the night before and the morning of your procedure, whereas Miralax is typically taken once a day for up to a week. Miralax usually takes 1 to 3 days to work. Suprep can cause side effects like stomach discomfort and bloating, and it may not be suitable for people with kidney problems. On the other hand, Miralax is generally well-tolerated but can cause nausea, bloating, and gas. Suprep is not available over-the-counter, unlike Miralax, which you can buy without a prescription.
Suprep is a combination bowel prep kit used to clean out your colon before a colonoscopy. It works by causing diarrhea, which helps clear your intestines so that your gastroenterologist can see inside your colon more clearly. The medication is a berry-flavored liquid taken in two doses that must be prepared according to the instructions. You take the first dose on the night before your procedure and the second dose on the morning of your procedure. Common side effects include bloating, stomach pain, and nausea.
Polyethylene glycol (Miralax) is an over-the-counter (OTC) medication used for occasional constipation. It comes as a powder that you need to mix with a beverage and then drink. Typically, you take a dose of polyethylene glycol (Miralax) once a day, for up to a week. Most people will experience a bowl movement in 1 to 3 days. Some side effects that polyethylene glycol (Miralax) can cause include nausea, bloating, and passing gas.
