Hello
I have gone through your question and understand your concern.
It is true.There are lots of serious diabetics that take oral anti diabetic drugs to control their
diabetes.
But as
endocrinologist i want to say that the choice of treatement for each diabetic is specific and it is decided taking into account patient values and lots of other elements like age,other chronic concomitant conditions and the respective treatement of these diseases.
If her treating doctors has decided to leave him on
insulin therapy even at home ,this means that this is the right choice for your husband,for the moment.
Anyway don't wory,if your husband adopt a healthy lifestyle,eat healthy and exercise regularly,i'm sure that soon,her treating doctor will put him on pill form medication and the problem of the cost of insulin each month for your family ,will be resolved.
Hope this information is helpful.
If you have other doubts,feel free and ask.
Take care.
my suggestion for you, is to consult a local endocrinologist for the follow up
