Several older human insulin products, including HUMULIN R and NOVOLIN R, are listed Over-the-counter in the FDA drug database (Drugs@FDA) as of 11 September 2026. That is why insulin can be bought without a prescription in some US pharmacies. That easy access is a large part of how misuse happens. | None recorded | None recorded | None recorded |

The full Canada answerInsulin in sport and the military
Whether Insulin is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status. Before you compete or get tested, look up Insulin by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
