"Wow been taking Monistat off and on for years with no side effects.  This time taking Monistat 1 was a nightmare.  Like the other posters on this site, I had insane burning and pain; never anything like that before.  I was up for hours before I followed the advice of a poster here and took a pain relief medicine and benedryl, and left a ice pack on the area for quite awhile.  Next day, it's still burning but the drugs are still in my system so it's manageable,  they CLEARLY changed the formula and omitted to tell us.  This should be removed from the market!"
