Dad's doesn't like it when my medications change. My enalapril compound began using a different manufacture and my furosemide tablets changed also. I guess we just have to trust that everything works the same way between companies. It's kind of scary (to Dad, not to me) when he realizes how much my life depends on blind trust; trust that the companies are making the pills the same way as each other, trust that they haven't been substituted with fake ones, that the pharmacists are paying attention when they're compounding my meds. Dad always says I'm here to teach him things; I'm sure that includes trust.
