I do not keep a vial of Antivenon because it is up to $6000 per vial and I would need upwards of 30 vials to treat a bad bite. Furthermore, AV can go bad in as little as 6 months. I do have a bite protocol and I have Miami's Venom 1 on speed dial. They are the closest place that carries the Thai Red Cross brand of AV that I would need for these little buggers. I could have a few vials transported to the hospital here in less than hour. Also, you need a prescription to get any AV and most doctors will not administer anything from your own personal stock since it is too much of a liability (especially if the vial has expired).
this is a heated topic among Hot keepers but I could go on and on as far as why I choose not to keep any AV on hand. I realize that it is a risk and I am okay with that.
