Novo Nordisk is withdrawing its production of human insulin pens so they can produce and sell more of their patented GLP-1 medicine for diabetes and obesity (marketed as Ozempic and Wegovy) in pen devices at markedly high prices in high-income countries. Because of this, many people with diabetes may have to make significant treatment adjustments, and some will be forced to change to using insulin in vials with syringes. For example, people with diabetes in South Africa, which has pioneered a shift towards the use of insulin in pens in the public sector by replacing insulin in vials (injected with syringes) with pens in 2014, had to ration insulin pens earlier this year when Novo Nordisk stopped selling human insulin pens to the South African government.
