What is Macrogol and Miralax?
Macrogol is a general term for polyethylene glycol (PEG) with a high molecular weight. It is commonly used as an osmotic laxative. Miralax is a brand name for a polyethylene glycol 3350 product, making it a specific type of macrogol [1]. Both are used to treat occasional constipation by drawing water into the colon, which softens stool and facilitates easier passage [1][2].

While Miralax is a specific product containing macrogol (polyethylene glycol 3350), macrogol itself is a class of polymers. Therefore, Miralax is a type of macrogol, but not all macrogols are Miralax. Different molecular weights of macrogol exist, and while PEG 3350 is common for laxative use, other weights might be used for different applications [1][3].
