It also has to be permitted to be in cargo, but the rules are more lenient.
Misinformation!

You also can pack frozen perishables in your carry-on or checked bags in dry ice. The FAA limits you to five pounds of dry ice that is properly packaged (the package is vented) and marked.
While the above passage doesn't specifically address meds it does show that dry ice, within certain limits, can go in carry-on luggage.
For insulin or other refrigerated meds I would be concerned that dry ice would be too cold. Frio Cooling Wallets claim to keep insulin safe for 48 hours. No frozen gel packs or ice packs.
FRIO COOLING WALLETS
2Flying with FRIO
We often get asked by our customers whether FRIO wallets can be taken on planes… and the answer is yes!
The gel in our wallets is not classed as a liquid substance so it is allowed to be carried in your hand luggage on board airplanes. You are allowed to carry essential medicines such as insulin but you may be required to have supporting documentation from a relevant medical professional such as a letter from your doctor or a copy of your prescription. Everything, including your FRIO, may be subject to inspection. However, once inspected and cleared, they are on their way with you to your destination!
