How long has miralax been around?

When did Miralax first come to market?

Miralax (polyethylene glycol 3350) has been around since the mid-to-late 1990s. It was approved by the U.S. Food and Drug Administration (FDA) in 1999 for treatment of constipation in adults. [1]

How can you tell the “start date” vs. earlier research?

The active ingredient, polyethylene glycol (PEG), had been studied and used in other contexts before Miralax as a branded product. What marks “Miralax being around” for most people is the FDA approval and product launch as Miralax (PEG 3350), which dates to 1999. [1]

Is Miralax still the same type of drug?

Yes. Miralax is still polyethylene glycol 3350 in powder form. The branded product’s long availability reflects that it has remained in use for constipation treatment for decades since its original approval. [1]
