It's a necessary request for the Rescue Venom Response Unit in Miami: to send medication to other states to help save a patient.

Miami-Dade County Fire Rescue Lt. Eddy Ballester says the unit received a call early Thursday morning from University Hospital in San Antonio, TX.

A physician there asked for 20 vials of anti venom to treat a 67-year-old patient who was bitten by an extremely venomous snake. The patient was in critical condition and in need of specific medication.

The shipment was sent soon after the call and was expected to arrive later Thursday. Ballester says the unit receives nearly two dozen requests within the U.S. for this medication. They have also shipped medication to other countries.
