REASONS FOR PRESCRIBING:

Medetomidine hydrochloride will be given by your veterinarian and its effects may be later ‘reversed’ with another drug (atipamezole).
Nervous or excited animals should be given 10-15 minutes to calm down after the drug is given to improve the response.
Your pet’s body temperature may decrease during sedation, so keeping your pet warm with towels and/or a hot water bottle may be helpful.
Veterinary staff will frequently monitor respiratory and cardiac function.
