I speak as a pharm tech...
It is near impossible to see someone store everything to the letter...
I know it may spend time in the hot car and in Texas (not at the pharmacy) I know most prefer there houses at 80ish in the summer
I know it's not completely effective
There was this one time where someone used 4 different types of birth control...
It all failed... I bet because of the way it was stored... In the bathroom where the temp went from hot and moist to cold and dry (being all above or below the recommended levels)
