Translator notes:

I think this song is about excesses, in this song, more specifically, about excesses in love, he treats love as a medicine (a steroid) that is used against loneliness (illness), love excess sinks you, causes "serious side effects" on you, then, I believe that the message that remains is "everything in excess is bad, even love" or something like that.
