You may have to find the right pharmacy which carries your meds, (smaller pharmacies or out in the boonies may not carry what you need) but they are here, and much cheaper. Also, there are many really good endocrinolgists who have also studied in the US and know their stuff. (and they usually speak English very well)

Before you need it, also find out which hospital in your area is best for your needs, if that day ever comes. PPPPP. The healthcare costs in MX are very reasonable. I pay 600 pesos a visit to my endocrinologist, (normally every 3 months) and have never left in less than 45 minutes. Unlike other experiences, he is patient, explains EVERYTHING, and invites questions.
