Can I use expired neomycin and polymyxin b sulfates, dexamethasone ophthalmic?
The bottle has been expired for a while now but it has never been opened and still has the seal on it.

Official Answer
by Drugs.comNo you should not. Firstly the eye drop has expired so its safety and efficacy can no longer be assured. Secondly it contains a steroid. Ophthalmic steroids must be used with special care. Used inappropriately could lead to an uncontrolled infection, steroid induced glaucoma and / or cataracts.
If you think the eye has been scratched you should see your doctor.
