(Reuters) - Danish drugmaker Novo Nordisk said on Wednesday it was initiating a recall of insulin cartridge holders used in some NovoPen Echo insulin pen devices distributed in the United States because the holders may crack or break if exposed to certain chemicals, including certain cleaning agents.
Using a device with a cracked or broken cartridge holder could result in delivery of a smaller dose of insulin than expected, the company said.
Separately, Novo Nordisk warned of a similar problem with NovoPen Echo and NovoPen 5 devices distributed in Canada.
Novo Nordisk said people with diabetes using a pen from one of the affected lots should replace the cartridge holder.
