Hi all, Jasper is on caninsulin and while it is bringing his numbers down it is very up and down. I asked my vet if he could go on lantus as I have seen from all the posts that it works better. Apparently there is a law over here that states that human medicines cannot be used on animals where there has been no testing and as lantus is for humans she cannot prescribe it for jasper. The only time it can be prescribed is if caninsulin is not working on him and as caninsulin is bringing down his numbers then it is obviously having a good effect. Now before people say switch vets as my vet is not a good vet for not prescribing lantus - my vet has been absolutely fabulous, they have saved jaspers life a good few times and has encouraged me to home test even coming out to help at no charge. They have suggested prescription food which we have tried to no avail and have accepted that felix is the only food he will eat (I will keep trying others) I do not want to change vets as jasper is really getting used to them now and as I say they have been fab. Has anyone else had this problem in the uk?
