Metronidazole
"I've been on this medication for 4 days, on the 3rd day my vision began getting blurry which caused a slight headache. Day 4 my vision is so blurred I can barely see. I began seeing white spots in my left eye only and now I have a migraine with light sensitivity. It's hard to work, walk or even have my eyes open. I agree with everyone else on here the taste is awful and it does work, but I would like to keep my vision. My Dr recommended I stopped taking it immediately until they find an alternative."
