(23 year old female) I was prescribed Ciloxan for a bilateral stapf infection that was invading my corneas. In the drug insert they do mention the possibility of anaphylaxis shock after administering these eye drops however, they make it appear as if it is a very minmal and rare occurance. Within minutes of administering my first dosage I started having difficulty breathing. I am an asthmatic, so my automatic response was to take my inhaler. After a few more minutes I started experiencing, dizziness, headache, tingling in my head, and addominal pain. My mother rushed me over to the fire station ( I was getting worse during the drive to the hospital) Once there things started to calm down. The paramedic told me that the only thing that saved me from having a more severe reaction than what I had was my inhaler. They administer epinephrine to counteract an allergic reaction, and the effects of the inhaler act in the same manner as epinephrine. Anaphylaxis is a serious side effect, just because the insert says that it is a rare occurance, be prepared for anything. It can happen.
