keratoconjunctivitis sicca
"I was diagnosed with extreme dry eye, in part due to past Lasix surgery, part occupational hazard, and part age related. My doctor put me on Restasis. It turns out I am allergic. I had none of the eye pain others described. But, my vision was very blurry impeding my ability to read and focus starting day 1. I increased my fluid intake, thinking dehydration. I had a "light " headache, sinus & throat issues getting progressively worse and I would suddenly lose my voice & experience dizziness. My blood pressure was elevated. My face became red & itchy.After feeling abnormalities in the blood flow around my heart, I stopped the Restasis. This all happened in 4 days.  Most of the symptoms left 48 hours after stopping. Restasis is not for everyone."
