have some eye drops for my cat ( DEXAMYCIN) and the botle reads not to use one month after it has been ..?

Question

open, it contains dexamethasone sodium phosphate 1mg
neomycin sulfate 5mg

i opened about a year ago, and now i need it again, can i use it?
what is the problem?

Answer 1

No... you cannot use it again. Either its effectivity has gone completely, or worse, it could have changed chemically and actually be harmful if used. Throw it out.

But DO call your vet and explain - he might be willing to sell you a new bottle without any other additional expense.

Answer 2

The warning is there because some human and animal meds can change chemically after they have expired, and cause bad side effects and this could possibly lead to serious damage to the cat/patient.
Perhaps you could just call your vet and get a new bottle?
Good luck

Answer 3

expired medication can lose it's potency rendering it pretty useless. Call the vet for a refill on some current medication.

Answer 4

I wouldn't use an expired medication, especially an eye drop, without asking your vet.
