Is MiraLAX Safe During Pregnancy?
For pregnant individuals experiencing occasional constipation, a common symptom during pregnancy, MiraLAX (which contains polyethylene glycol 3350) is listed among over-the-counter medications generally considered safe 1.
The reason for its safety profile is how it works in the body. MiraLAX functions osmotically within the gut, meaning it helps draw water into the stool to soften it and make it easier to pass. Importantly, it is not significantly absorbed systemically, meaning very little of the medication enters your bloodstream 1. This localized action reduces concerns about potential effects on the developing baby.
