lately ive been using weekly pill planners. you know those pill holders that have 7 boxes for each day of the week. a few days ago my heartburn and reflux was getting really bad despite taking my pariet. i couldnt understand why. then i had a thought, perhaps they were going off in the pill planner? after all, when i put my fish oil caps in there the capsule gets all soft like it has already started to break down. i looked up the instructions for pariet and it says it must remain in its packaging until ready for use. i have gone back to taking it straight out of the package and my stomach problems have gone. ive decided im going to stop using all of my pills in the planner. if it can make the pariet and fish oil go off im assuming it would do the same to the rest. so unless you are 100% sure your tablets can be stored outside of its packaging, dont use these planners! they may be convenient but your medicine wont work!
