penicillin procaine G didn't get put back in the fridge- can I use it?

[TeamChaos]

The penicillin bottle didn't make it back to the fridge after the last dosage. It was in the cool basement. Will it still be effective or am I out the money? Thanks for any info.

It might be best to ask a vet or pharmacist. I couldnt find anything certain on the internet. Grrrr.
