A 35-year-old male asked about a male:

Can just 1dose of miralax cause diarrhea for a couple of days? can it really last in your system that long?

Yes, it can.Since there is not specific dosing or MiraLax other than the 1 capful recommended to start with, it does work “too well” for some people. If loose stools continue, wait before you take another dose and if you’re needing it again, take a lower dose. Please contact your doctor if lasting much longer or if any blood in your stool.
