Using Outdated Flea Meds

[stephanietx]

A young kitten showed up in our backyard last week and we brought her inside.  She's living in out spare bedroom until we figure out if we want to keep her or adopt her out.

  We took her to the vet last week and the vet found one lone flea on her.  I have some outdated kitten Revolution.  Can I use that on her with no ill effects?  Don't want to buy new if I can avoid it, especially if we don't keep her.

Depending on how long expired it is, the only possible change might be the potency, but even that I highly doubt.

Like if it's been expired for 5 years then the potency is likely not as effective, otherwise nothing will change where it will become toxic, just maybe weaker.

It's 2 years out of date.  Do you think it's still viable?

I would use it if it were me. 

If anything it may not have the same amt of potency it once had but nothing dangerous or harmful.
