Board-certified and expert orthopedic hand and upper extremity surgery, Dr. Erin Nance, speaks to BestLife about household items that go bad and could become dangerous.
She is quoted saying:
“Eye drops are generally formulated with a preservative that keeps the product sterile for 28 days after breaking the seal,” says Erin Nance, MD. These preservatives are designed to prevent bacteria from growing in eye drop bottles, which extends their shelf life—but they still need to be tossed four weeks after opening.
“If you use expired eye drops which don’t have active preservatives, and the tip of the eye drop bottle becomes contaminated [when] it touches a part of your eye, this can cause a bacterial infection if those drops continue to be used,” says Nance.
