Compare Golytely vs. Miralax

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

PEG 3350 with electrolytes (Golytely, Nulytely, and Moviprep) and polyethylene glycol 3350 (MiraLAX) are both osmotic laxatives used to treat bowel issues. They work by drawing water into the colon to help with bowel movements but there are some differences. PEG 3350 with electrolytes is mainly used for bowel cleansing before procedures like colonoscopies, while MiraLAX is used for occasional constipation. PEG 3350 with electrolytes is a prescription medication, whereas MiraLAX is available over-the-counter. The dosing for PEG 3350 with electrolytes involves drinking large volumes of liquid, often up to 4 liters, while MiraLAX is taken once daily in smaller amounts mixed with a beverage. PEG 3350 with electrolytes can cause side effects like nausea, vomiting, and electrolyte imbalances, while MiraLAX may cause nausea, gas, and bloating. Additionally, PEG 3350 with electrolytes has more serious risks, such as kidney problems and seizures, especially if you have certain health conditions.
