My son is 22 and he has been with Fluoxetine for many years (since he was 15).He was diagnosed as depression. He can get very angry and violent about once a month.He yells, punches holes in the wall and hit himself, talks about all violent words, seems very depressed. In about 1- 2 days, he calms down. When he is not angry, he is such a nice young man. We joke around in the family and he has so much sense of humor. Now he refused to see doctor and take meds anymore.He has been nervous when talking to stangers and he hates that feeling. He was very social when he was a kid (before 12 years old). He is OK when hanging with his friends.I m wondering if Fluoxetine causes his anti-social, or gets angry once a while.Should he switch to another med? Such as Sertraline? Thanks in advance!
