Concern is that due to the lack of education provided pharmacist, mistakes occur that could be avoided. Medication, doses, and interactions are not common knowledge to pharmacist and providing a script for every medication so that pet owners may fill meds at mainstream pharmacies opens the concern for issues. I have had pharmacist deny thyroid medication thinking I was overdosing, pharmacies have filled heartworm prevention without script from doctor which may can cause issues in heartworm positive dogs, I have had scripts filled in liquid form that containing additives that are toxic to dogs. Pet owners have the option to request written scripts, but it should not be mandated for every script made. This mandate may add to confusion regarding scripts and giving medications if the pharmacist says one thing and the veternarian says another. The doctor and the pet family should be allowed to make the decision together when it is appropriate for a written script.
