Has she had a bad reaction?
Or been abused for taking them?
I had a severe reaction which resulted in me collapsing in a road and causing a traffic accident (someone is paralysed, another was seriously injured as a result) after I was told there would be no side effects and then blamed for the accident by mh team. The police agree but the mental health team said I did it delibrately as it was impossible for meds to cause that (actually untrue as any mh meds severely effect my neurological condition for which there are no meds or cure - mh team are dismissive of the condition and as such kept giving me meds causing worsening of my neurological condition which meant I was forced to choose).
I was also told "side effects" are not real, and then by the same dr if someone has "real" side effects then they're minor and disappear after two months. I never managed a day safely. Telling me to phone if I didn't recover consiousness when I live alone was very telling of just how serious they took the seizures they induced.
I was given meds when younger after being assaulted and blamed. I was then assaulted by my parents who see mh meds as something only the weak and pathetic rely upon, they flushed them, assaulted me and said if I was so weak to need pills I should just get over it, get married and have babies like normal kids and get out of their home.
Many years later I've viewed the medication leaflets for what I was given (having not been allowed to be given the leaflets at the time) and know it was dangerous for me to be given them. Denying someone's medical (physical) disability is a very foolish thing to do.
They've tried giving me meds since, stating that it was just silliness but it wasn't. I've also been tricked into taking meds disguised as pain relief as an inpatient which made me very unwell as well, again, I was blamed for wanting to be ill.
My notes now have in huge red letters on the front that I am a med denier. I'm not. I know people whose lives have been changed hugely by them. BUT I struggle massively with discussions about meds because of my experiences. No one in RL is aware of those struggles, nor will they be, as I carry a lot of shame. A person nearly died because of me taking meds, another is paralysed for life. I know my behaviour around meds is extremely hard for others to understand as people have had this conversation with me, but I cannot bear anyone knowing what has happened. Especially when the mental health team are so adamant it's all delibrate on my part.
I guess what I'm saying is it may not be as simple as you think, often these things are not. Perhaps just avoid the subject as hard as you may find that.
