I have been depressed lately and my doctor put me on Lexapro last week. After the first pill, which I took at lunch, I felt nauseous for a while, but then I felt sort of relaxed and a little 'fuzzy-headed' that night. I took my blood pressure (I was curious if it would be really low, and we have a machine since my husband has blood pressure issues), and to my shock it was 155/95 !!?? It never got below 140/90 on several attempts, and that is much higher than I usually get on the machine. In fact, I am usually below 120/80. Since then, I cut the Lexapro in half for a few days to get used to it, nausea wise, and the blood pressure dropped, but not all the way to normal, and today I went back full dose and it was high again. I have looked high and low for this as a side effect but haven't found much on the internet. Some other SSRI's, like Prozac, do list hypertension as a possible, but uncommon side effect, but not Lexapro. Am I correct in thinking this is a side effect? Should I discontinue the medicine after only 4 days? If it is a side effect, how long will it take for normalcy to reestablish? I am a 40-year old female.
