60 mg. a day is not considered HIGH from what I can find, but it is on the "high end". Having just talked to my favorite psychiatrist, he really likes to use Celexa in patients who are depressed with suicidal thoughts, mainly because it has less side effects and does not usually cause a problem with other medications. He normally does not go over 80 mg a day UNLESS he has seen drastic improvement in his patients after starting it. He has prescribed as much as 120 mg a day on several patients, but he said that is not common. So, I still have not really answered your question, but I tried to learn more about Celexa and doseaging.

How long have you been taking it and did you start at 20 or 40 mgs. a day?
