Hi. Lexapro is the first and only medication I've ever taken for my anxiety/depression, and I only took one 10mg pill. This was yesterday...

I thought I was going to die. My heart was racing and pounding, my pupils were hugely dilated and my eyes felt like they were gonna pop out of my head (even a day after, my eyes are still sore). I had blurry vision, nausea, chills, and my arms and hands felt numb. I felt grindy like I had taken an overdose of some sort of speed. My head felt floaty and disconnected and I had a hard time focusing...

So I called my doctor this morning and was informed through an "advice nurse", since I wasn't able to speak directly with my doctor, that she wanted me to continue taking the lexapro, that I was feeling like I was because it was changing my brain chemistry and that she wanted me to take Klonopin for the next week or so while I adjusted to the medication.

I told her there was no way in hell I would put another pill of that stuff into my body. It literally felt like poison.
If it had been mild, or even moderate side effects, I would have been willing to try, but this just felt so wrong.

Has anyone else had a severe reaction anything similar to mine?
At this point I'm terrified to try anything else. If I have this kind of reaction to one, it makes me wonder if this whole class of drugs is off limits to me?

Any thoughts would be so appreciated.
