I got a prescription for Drysol from my dr but I don't know how to use it!?

My dr put me on meds that raise my body temp so then to counter act the sweating he gave me a prescription for drysol. I just picked it up and am confused on how to use it. It says not to use any other deodorants or antiperspirants while using this. Does that mean only while its on or not ever? He said it would help w/my newly found smelly problem but I am concerned that it isn't going to. HELP!

all you do is squeeze the bottle, and put the liquis that comes oout on your armpiots. and you only use deoderant when you DONT have it on.
