Answer:
Step-by-step explanation:
I think it's true.
A patient should always be aware of what he/she puts in their mouth and swallows. You don't really know, unless you study what the "medicine" does. And you should. You can trust your doctor to know what he/she is doing, but you should know as well.
You may uncover a reaction to what you are taking especially if your doctor does not know what you are doing. That's especially true of alternate medications which may work against what is prescribed. ]
