Hey mrsD, I've seen several posts where you've said that Miralax is under reconsideration by the FDA, but my searches here haven't turned up any links to more info. I did find this:
http://www.fda.gov/downloads/Drugs/G.../UCM166481.pdf but it looks pretty old (pre-OTC status) and talks about false claims rather than any concern for safety.
I've also found many references about a recall due to faulty container caps. Do you know of any other concerns that might make me want to stop using this product (aside from the creepy sound of "polyethylene glycol", which reminds me of anti-freeze, or something awhile back about dangerous Chinese imports of something)?
