Should my boyfriend get off addiction to pills?

My boyfriend is on antidepressents, tranquilizers, plus sleeping bills. He has been on tranquilizers and sleeping bills for 8 years and antidepressents for 1 year. I have a problem with him being on them, and told him needs to get off them. He won't go see anyone to talk with and he is very paranoid about everything. Am I wrong by asking him to get off them? And what is the best way to handle this - don't want him to get off them and blame me....
Thanks for your help.

Your boyfriend should discuss his medication with his psychiatrist and follow his advice.
