So I've been taking Citalopram for over 10 years now going between 20mg and 40mg. Currently taking 40mg but I feel they are bo longer working so my Dr has recommended Sertraline. She has advised me to take 20mg Citalopram for the next 2 days then nothing on Friday and straight on to Sertraline on Saturday. It just doesn't seem right... I thought coming off Citalopram would take weeks of gradually lowering the dose? Or because Sertraline is another SSRI would that cancel out any withdrawal from the Citalopram?
