Jack has been on Citalopram for 6 weeks, during that time ,from being able to walk upstairs and in the garden, he has now got to the stage where he cannot even walk very well, also he is very sleepy and complains of pains in his back and stomach, does not want to get up ,wants to lay down all thetime. has anyone else had this reaction from this drug. why he was given it in the first place I do not know, all he needed was a light sedetive.untill I can see the doctor again I feel like taking him off the tablets. they seem to have taken away any enjoyment that he had. coments please.
