Washington – The Food and Drug Administration (FDA) issued a warning to consumers not to use certain kinds of eyedrops as they may include unapproved medications that cannot be sold legally in the US and may be infected with bacteria, fungus, or both. Consumers were advised not to use Dr Berne’s MSM Drops 5% Solution and LightEyez MSM Eye Drops. “Using contaminated eye drops could result in minor to serious vision-threatening infection which could possibly progress to a life-threatening infection,” the FDA said.
