Well, I'm not a doctor so take this with a grain of salt. I've never heard or read anything from a realiable physican that recommends going cold turkey off any anti depresessant. I would perhaps ask for a 2nd opinion regarding your loved one's current symptoms.

In my case, I tried to go off Prozac but I was very careful. I started by cutting them in quarters and taking 2/3 every day, then taking one every other day. I tapered off about 1/4 tablet each week for 6 weeks. I did not have what you would call withdrawal symptoms, but I did notice a change in my mood. So, I went back on it after a couple of weeks. I probably should have waited longer to see how long it would take (if possible) for my mood to get a bit happier, but it didn't look promising.
