I really hate to say this, but this number is no longer a 24 hour hotline. I worked at the K-State Vet Med Teaching Hospital for a little over a year before they decided to change this policy.
You can still call Monday thru Friday 8-5 to speak with Dr. Ohme free of charge....However, afterhours, they only accept phone calls from other vets.
You can still call this number to speak with a vet about any other issues you may have...you just won't be able to speak with a toxicologist.
