Warning issued over possible contamination of copycat eyedrops

(CNN) – The Food and Drug Administration issues a warning about unapproved, copycat eye drops.

According to the FDA, “South Moon,” “Rebright” and “Fivfivgo” should not be purchased or used.

Officials say these products lack brimonidine tartrate, an active ingredient used in approved eye drops.

In addition to that, testing of South Moon samples came up positive for a bacteria that can cause eye infections.

So far, there is no word where these products came from, and an investigation is underway.

The FDA says the copycat products can be easily mistaken for Lumify brand eye drops, which are approved for eye redness relief.
