It’s possible that she appears normal when speaking to the Dr. and when she picks up her prescription. Perhaps, before ‘putting the fear of God’ in him, you might contact the Dr.’s office and explain that her observed behavior is terrifying and give him specific examples. Perhaps ask if he might consider referring her to a psychiatrist since she’s not responding as anticipated to the drugs. This way you don’t alienate the Dr. - you want his help at this point. If he were intentionally doing this - I’d want to use the method you explained but at this point, he doesn’t appear to know. And it might influence him just by letting him know you know and have reported it to him.

He won’t or can’t talk to you about her. Get a second opinion.
