Hi Mark, I am uncertain about the cost of insulin, although I know it is available here. We have a doctor in Quito that we like a lot. He is Dr. Davalos and he is a member of the International Association for Medical Assistance to Travelers. He speaks perfect English and his tel # is +593 (2) 2260 575 and 2265 783 and 2260 228.
Also, Sarah Dettman is a former Peace Corp nurse and has been living in Ecuador for 25 years. She’s the person we turn to whenever we have a medical question. She may know about the costs of insulin. Email Sarah at s.dettman@yahoo.com.
