I am 73 and I received my first infusion of Reclast on Mar. 24, 2025. I was tired and achy that night, which I had been told to expect but was fine the next morning. That evening while washing my face I noticed my left eye hurt slightly behind my eyeball. I had never had that feeling before. I did not connect the infusion with this as I had not been told this was a possible but rare side effect; nor had I read that in any of my research. The pain and swelling got worse over the next 3 days. The arthritis center where I had the infusion told me to go to emergency. It was Friday and I called my opthalmologist for an appointment for Mon. Over that weekend, it got much worse, so much so that I went to the emergency on Sunday. I told them that I thought it was from the infusion but the ER doctor decided it was an allergic reaction and prescribed me a antihistamine and a stomach pill, both of which I was already on if they had bothered to read my medications. When I went to the opthalmologist the following day, my left eye was completely swollen shut. I again told him I thought it was a side effect of the infusion. He didn't say it was or wasn't from the infusion but was concerned there might be something else going on, such as a tumor. He directed me to get a CAT scan the following morning. It did not show any mass. I was prescribed 40 mg. Prednisone for 7 days, Prednisolone AC 1% drops-1 drop 2x per day, sodium chloride eye ointment--3x day along with Pantoprazole 40 mg ( in case the steroid upset my stomach). After seeing another eye doctor at Cleveland Clinic, and taking every test for possible infection, they both conceded that my reaction was a response to the infusion. It is now almost 3 weeks out from the infusion and my vision is still adversely affected in the right eye. I have not yet had a follow up with the infusion doctor or the eye doctors, but the eye doctors that I previously saw recommended that I not continue the infusions. I do not plan to.
