GaviLAX Reviews

For Constipation "Absolutely disgusting!! Something is wrong with this stuff. I have taken miralax and generic forms from two different stores and had no issues with taste or smell. They USUALLY have no smell nor taste. This stuff from the pharmacy smells like chemicals or some type of metal mixture. You can not mix it with anything to mask this nasty taste. I have tried 3 different times from my pharmacy thinking it was a bad batch but they are all the same. How can I expect my child to drink this if I can not even bare the taste nor smell??"


For Constipation, Acute "3rd bottle of GaviLAX I got from my pharmacy that was rancid. Not sure what chemical(s) are added to it but the smell and taste are definitely bad. Taking it back to pharmacy for exchange to different product. Even grocery store generic tastes better (meaning no taste or smell). "


For Constipation "I've been using Poly Glycol 3350 for 5 years through a major drugstore chain. A few years back, they, in their infinite wisdom, decided to partially switch suppliers to Gavilax. Upon opening a container, I was shocked at the strong chemical smell. Regardless, I tried it in my coffee: ugh!! Without exaggeration, it reminded me of WD-40. Until recently, when placing my 60-day order, I was able to finally obtain the different brand that I'm accustomed to (after an extended delay). It appears that my drugstore is now exclusively sourcing with this brand. If there was a numeric "0" on your Rate this Medicine, that would be my response"


For Constipation, Acute "It tastes bad. I have used miralax for many years without any issues. I can not take something that tastes this bad, twice a day."
