I was prescribed Avelox for a sinus infection. I picked it up and promptly took one 400 mg. tablet. Within thirty minutes, I started feeling "strange". My wife drove me home from a restaurant as I began to feel things crawling on my skin. Occasionally my vision would rotate 10 degrees left and then flip back to normal. I could feel my heartbeat in my lips. Extreme anxiety and confusion. It reminded me of dropping acid many years ago! We are on vacation and will not spoil it by taking the remaining nine pills in this $120 prescription! Yuck!
