My physician prescribed Paxil for me over 7 years ago, the side effects were dry mouth and felt a bit sleepy most of the time. The good part was I did not have any anxiety or panic attacks. Then, about 5 years ago the doctor changed my medication to Celexa. With Celexa I still had the dry mouth, but felt more awake and less sleepy. Then about 2 years ago the new drug Lexapro came out. My doctor changed my medication to Lexapro and in doing so cut my dosage in half. I still have the dry mouth side effect but I do not feel the slightest bit drowsey or sleepy with the new medicine. I have to say each time my doctor changed my medicine it was an improvement over the last one. I feel the side effects were a minor compromise to being rid of my Anxiety and Panic attacks. You have to weigh the benefits that you receive from the medication against the side effects you are experiencing. In other words which is worse? I am Anxiety and Panic Attack free because of this medication and I thank God for it, or should I say I thank God for giving man the wisdom and knowledge to be able to create this medication.
