I believe this is just misunderstanding. I know what OP is talking about. Me, for example, I always check all meds I'm prescribed for ingredients and side effects on https://www.canadapharmacy.com/. I'm really scared if there is sth mentioned about eye sight risk. So I ask to change the meds. This is not meant I want a different way of treatment, but only change the medication that won't have that active ingredient that might possibly cause problems for me.
