MiraLAX Laxative Powder

MiraLAX is an osmotic laxative that works by drawing water into the colon to soften stool and restore natural rhythm, typically producing a gentle bowel movement within one to three days. Unlike stimulant laxatives, it doesn't force the intestines to contract, which is why so many people — and their doctors — reach for it for occasional constipation without the cramping, urgency, or dependency concerns. The active ingredient is polyethylene glycol 3350 (PEG 3350) at a 17-gram dose, the same formulation trusted for everyday relief and for prep in some clinical settings.

What people ask most is simple: how do I take it, and will I taste it? Each 17-gram dose dissolves completely in 4 to 8 ounces of any beverage — water, juice, coffee, tea — and stirs away clear. The powder is genuinely tasteless and grit-free, so it won't change the flavor or texture of your drink, which matters for older adults, picky kids, and anyone managing it long-term under a provider's guidance.

This collection carries Bayer MiraLAX in the formats that fit different routines. The 8.3-ounce bottle covers about 14 doses for short courses, while the larger 17.9-ounce and 26.9-ounce (45-dose EZ Pour) bottles suit ongoing use and include a measuring cap for accurate dosing. If you want zero measuring or need portability, the MiraLAX Single Dose Sachets and the 10-count boxed packets deliver one pre-measured 17-gram dose each — ideal for travel, caregiving, or facility supply closets where consistency counts.

MiraLAX is intended for occasional constipation and short-term use unless a healthcare provider advises otherwise. For a broader look at bowel-care options, browse our full Laxatives selection.
