I was on lexapro (closely related to celexa) and after a week the headache made me quit. It was 24/7, and nothing helped the pain. 5htp and st johns wort have the same effect on me. The only one I can tolerate is Prozac, but after 15 years, it just doesnt cut it any more.
I did a search on the internet under Celexa and headache, and it came up with tons of hits. SSRI's cause headaches in some people. I stopped taking it today, since I've only been on it for just over a week and a half, I don't think it had really kicked in anyway.
I have been taking Celexa for a month at 10mg/ day and am switching to Zoloft because of increased headaches and dizziness. I understand I could have the same reaction to the new medication but because they are all slightly different I hope I will have better luck. The drowsiness I could tolerated but headaches no!
