A group of Minnesotans has banded together in a "caravan" to regularly travel into Canada and obtain insulin at a cheaper price than they could in the United States amid rising drug costs nationwide.

Quinn Nystrom, a Minnesota woman who formerly sat on the city council of Baxter, Minn., tweeted on Saturday that the group of six state residents had obtained a supply of insulin, needed for Type 1 diabetes treatments, for just $150 at a Canadian drug store, far cheaper than in the U.S.

"1 vial of Novolog in the USA = 10 vials of NovoRapid in Canada," she tweeted, adding: "=6 happy & grateful ppl w/type 1 diabetes & T1 Mom’s"

SUCCESS! -5-hour road trip. ✅ -Insulin purchased where NO prescription was needed! ✅ 1 vial of Novolog in the USA = 10 vials of NovoRapid in Canada ✅ =6 happy & grateful ppl w/type 1 diabetes & T1 Mom’s #CaravanToCanada #insulin4all #MNinsulin4all pic.twitter.com/0B0jelAQkj — Quinn Nystrom (@QuinnNystrom) May 4, 2019

In an interview with NBC affiliate KARE news in Minneapolis, Nystrom said that purchasing insulin in the U.S. was not a viable option for her family.

"How can you debate saving $3,000 with a five-hour road trip?" she asked, adding: "So I paid, in January, just $600 for two vials for a one-month supply."

Though insulin has changed little since it was introduced nearly a century ago, its price has skyrocketed in recent months.

Congressional leaders have pledged to investigate spiking prices amid reports of Americans dying after rationing their insulin due to high costs.
