I had to start taking medication when I was 7 and was totally against taking it . But my parents would not stop being very persistent that I needed to take it. Sometimes it would take hours , but after a week or so I realized I lost and they would not leave me alone till I took so I gave in . Only advice I can give is be very persistent and don't stop sooner or later she will take it with no problems . As a parent I feel for you and just stay strong together and stay positive hopefully she grows out of needing to take medication.
