Does anyone know how long it keeps? I can't find an expiration date anywhere on the packaging.

We seem to be real lucky in avoiding fleas, so I don't normally use this stuff. Found one on Riley the other night, though, and remembered that I had some in the drawer. Problem is, I bought it god-knows-how-long ago. A year maybe. Maybe longer.
Would it still be good? Still safe to use?

That's odd, I'm pretty sure I remember seeing an expiration date on the packaging of my Advantix... I'll check it out when I get home and let you know how far in the future it is, if you haven't gotten an answer from someone else yet.

Thanks!
I thought it was odd, too. You'd think there would have to be an expiration date - it can't just be good indefinitely. (Can it??)
But I checked again and there's nothing. Lot numbers, but no expiration on the packaging, inside or out. And nothing on the vials, either.

You should be able to call the pharmaceutical company and give them the lot number if all else fails. I'm sure they'll be able to tell you if it is still good.

I think it has a 2 year shelf life. I recently bought some Frontline and it is good until 2012. I would think it would be similar.

Good idea. Just called Bayer.
If anyone else is interested, there's virtually no expiration on the Advantix. She said that it has a proven stability of up to 7 years, as long as the tubes remain sealed.

This is funny, just today I had the same situation which brought me to this site. I recently found some fleas on my dogs, found some "old" Advantix in a drawer with no expiration date on the package, and googled this question.
