HI MissKim, my dad went through this, he wouldn't take his meds at home. They gave him hormone shots at the Dr. and a whole box of medicine at home, but he never took it. Said he didn't like how it made him feel. You know what they say about leading a horse to water, I think it applys to Dad's and medicine too.
If you will repost this as a question in the "questions" tab at the top of the page, you will get responses from lots of people, as an update not as many people see it.
Thanks for posting, hope your dad is doing as well as he can.
