After discontinuing Prozac several patients have observed feeling more energetic and ambitious. It made me think of a footnote from the Prozac best seller:
At the end of Listening to Prozac (1993), the book that catapulted Prozac into 35 million customers, there is a footnote that questions "...whether antidepressants . . .promote tumor growth:" ... "The study raised questions as to whether antidepressants might be dangerous to patients who already have cancer or who have some exposure to carcinogens."
