how long does cd/t keep, open?

[mygoat]

I've got a bottle of cd/t that I planned to vaccinate my two 4 week old doelings with today. but on the label it says use entire contents when first opened. I opened it about 2 months ago and it's been refridgerated since. can I still use it?? I've got an unopened bottle as well if I can't use this one, but i just don't want to waste this one if I can still use it.

Hmmm my CDT does not say anything about using it all at once. I think it should be fine

Most vaccines say that. I think one reason is their goal is to sell vaccines. Another is possible contamination. If you use a clean needle to draw it up and another one to give the shots, and also keep it cool, theres no reason for it to go bad. There should also be an expiration date on the bottle. That is what I would go by, assuming its been kept properly cooled
