Just had a fluorescein injection for retinal photography today and after the first 2.5 cc - before any pictures could be taken - I passed out. For the following 5 hours was in recovery in the ER with two bouts of vomitting, severe nausea, headache, vertigo and muscle weakness. Heart rate dropped below 45 and BP was elevated. Tx with IV fluids, Benedryl and something for nausea (wasn't told what it was). NOT a pleasant experience and WON'T be doing it again!
