Hi Cathy. My older sister was on Prozak for six years and it simply stopped working. She told her GP and was immediately changed to Citalopram. He said it was a common fault with this drug. Google " prozak stopped working" and you get 1.2 million results as opposed to "Citalopram stopped working" which gives about 0.5 million results.
However, this does'nt mean it's going to happen to you Cathy, you might get lucky like your friends, and the millions of folks that take it for many years with no problems.
Regards, Gordon
