Firstly, for anyone completely out of insulin, please know novonordisk offers a patient assistant program and will cover your insulin free of cost. I used this during college. If you can't even afford a doctor, there should be free health care clinics willing to sign those forms required. I used my college's clinic once to do so as well. The down side is signing away your personal health records.<p>As a type 1 diabetic myself, Walmart's offerings on R or Regular insulin saved me a few times. Once when I was simply out of insulin and did not have insurance. Then when I was caught in another city for work and ran out due to needing to extend my stay. I am slightly disappointed to see that one, the price is not the same as their human insulin which is around 25 dollars per vial I believe. Two, it will require a prescription. The times I bought their cheapest insulin, this was not required. However, I hope this is the right direction.
