"I've been on Restasis for several years and have done well on it. My insurer stopped covering Restasis this year, but covers Xiidra. I'm not sure why since they're priced similarly. Restasis is actually a better value because it has .4 ml in every vial (I can stretch out a 90-day supply to 180 days) vs. Xiidra's .2 ml. I decided to try Xiidra. Right away, my eyes burned and itched and are extremely red. I've only been on it for 5 days. I don't know how long I can tolerate the Xiidra. I don't know if I should discontinue using the drops because I suspect I might be allergic to them, or will these side effects subside?"
