We have firsthand experience buying brand-name insulin for personal use in Tijuana, Mexico, for less than 5% of retail in America. Read about that experience on T1International’s blog, or watch the video documents of our trip in January 2019.
Our neighbors to the north offer a couple options for buying insulin. The first is highlighted in this YouTube video by Erik Douds. The second is for those who can’t make the trip: Marks Marine Pharmacy.
In a pinch, check out your area’s Craigslist page and use the search term “insulin”. Las Vegas and Miami, for example, usually have a handful. Check the expiration, ask about refrigeration, get insulin.
Not the best, but it will keep you alive. Buy refrigerated, workable, older insulins like R and NPH over-the-counter at Walmart. Learn how to use them here. And don’t die.
