I apologize. I misread your comment.
Var won't impact the pill and if you keep the dose at 5 to 10 mgs she won't need to do anything after but may have some hormone disruption for a few weeks after ie: monthly cycle off, moodiness etc.
If she has more specific questions, she can always pm me too. Most women will gain some weight on var too... Which is usually the idea... Gaining muscle.
Good luck!
