I think this song is about society as a whole silencing those who have different opinions than they do. The medicine symbolizes forced values and ideas.
"All these ideas keep swimming, running through your head.
Quick, we'll drown them with this fix."
That's basically saying having ideas is a bad thing, so we'll wash them out for you.
"Your opinions are a thing of the past,
so tilt your head back and swallow this."
Again, this is saying that you're not allowed to think on your own anymore, so you have to be one of us.
