A secondary location for IM injections is the back of the thigh. Be sure to inject straight in, not from the side. When making multiple injections, keep injection sites at least 5 inches apart, being careful not to reuse injection sites. Avoid injecting in wet or manure covered areas to minimize the risk of injection site reaction. Properly restrain animals.
Proper restraint is essential to minimize the risk of human injury.
Also work cattle in a manner that will minimize the possibility of damage to the animal and reduce the risk of injection-site reactions.
