Q
Drugs should never be given intravenously?
A
Answer: Procaine penicillin
An acute reaction will occur due to CNS procaine toxicity.
Procaine is a local anesthetic and helps to give the procaine penicillin the long-acting effect, so it can be dosed twice daily. If injection is given intravenously, it causes severe trembling, thrusting backwards, and possibly collapse. If this does occur, treatment is supportive care, as long as the horse does not damage its neck or spine.
There are intravenous preparations of penicillin such as potassium penicillin but procaine penicillin is always given IM.
