I don't know if you can take it all your life. I DO know that after years of use, sometimes you have to keep increasing the dosage to get the same effect. My mom was on Paxil for ten years and had to switch over to Zoloft as the Paxil no longer worked.
I went on it knowing the doc wanted me off in a year...maybe two, as it was prescribed for the depression/anxiety that came with mutiple deaths in my family over a very short period of time. It did it's job for that an I am thankful. But I can honestly say that I would have never started it if I had known this would happen to me. It is unrelenting and even with all my other medical conditions, I cannot think of day with all of them acting up at once that I have ever felt anything like this. The headaches and brain zaps are wearing me down, and to begin taking Lexapro again may or may not relieve these symptoms.
I wrote to Dr. Rosenfeld on Fox news never expecting a reply, just asking if there was something to minimize the zaps. He wrote back immediately. 'Only time and patience and it is the price some people pay for going on these drugs.'
Having said that, not everyone will experience the severe withdrawal that I am going through. Again, it is important to ask you doctor what you can expect if you decide to start an SSRI for a limited period of time. Mine did not tell me about withdrawals.
