###Human: Can Celexa cause side effects if discontinued in the middle? ###Assistant: Hello. I have gone through your query in detail. I can understand what you are going through and you have my sympathies for the same. Though your mental health is quite disturbed right now, you have many reasons to be optimistic as far as your anxiety, depression and post-traumatic stress disorder is concerned. First thing being, that you were doing good on high dose Celexa (Citalopram), which means that your illness responds, once you have attained sufficient dose of a suitable drug. Secondly, currently your anxiety symptoms have reduced to some degree, but there are remaining symptoms which are because of depression (anxiety itself could be a symptom of depression to some extent). You might experience some anxiety initially when increasing the dose. For which you can take tablet Ativan (Lorazepam) when necessary. Once your depression improves, you will find a lot of your problems disappear on their own as they are directly or indirectly related to depression. Take care. Life stressors and changes. Major depressive disorder or PTSD or generalised anxiety disorder (GAD). Optimization of the dose of current medications.
