I have been taking Fluoxetine (20 mgs) for 6 years with much success. I made a boo boo and didn t pickup my refill. I have been feeling good for so long I thought maybe I didn t need it. Now its been 2 months and suddenly I m a mess. I picked up my RX and started taking it again 3 days ago. I have fear, panic, anxiety, and trouble making decisions. How long before it starts working again? And why did it take 2 months for my panic and anxiety to set in?
HiThanks for using ChatDoctor Half life of fluoxetine is 2 to 6 days and a  ChatDoctor.
