For me personally yes. My stutter got worse when first starting citalopram..Granted I work in a high stress environment, and had just started the job which didn’t help😂 But my stutter definitely trickled off quite a bit after a full month of taking citalopram. Recently I also started taking Adderall again for my ADD which has helped tremendously cause my words and brain are on the same speed of that makes sense??😁
