(Crotalidae) Polyvalent

Important and Exclusive Aid for Successful Therapy of Venomous Snakebites

ANTIVENIN (Crotalidae) Polyvalent neutralizes the venom of the viperene snakes, including all North American species of rattlesnakes, copperheads and cottonmouth moccasins.

Efficacy Proven in Field Use

  • Sixteen practicing veterinarians had uniformly successful results with Antivenin in patients having mild symptoms at the time of treatment

Fast Action: Key to Successful Therapy

The success of ANTIVENIN appears to be directly related to how rapidly the animal is treated after being bitten–the shorter the time interval the better the chance of recovery.

  • Only 45 percent of the field-trial dogs survived if there was a time lag of 4 hours or longer, but survival rate almost doubled if elapsed time was less than 4 hours.
  • Being completely prepared for prompt treatment is imperative.

Now Readily Available

  • The ANTIVENIN product is in good supply and BIVI anticipates it will remain this way. Continuous manufacturing improvements have been made by BIVI to be a reliable supplier.
  • Antivenin does not stimulate active immunity to protect dogs from venomous snake bites. It is a refined preparation of equine serumgloblins used to treat dogs subquent to a snake bite.
