“All insulin products work the same way and can be swapped freely.”

Misleading

This statement leaves out a limit that changes its meaning.

Insulin products can differ in how fast they work and how much medicine they contain. They can also differ in how they enter the body and what their FDA labels allow. Some biosimilars can be substituted under state law. This does not make every insulin product freely exchangeable.
