Humulin R Cartridges (Insulin Human Biosynthetic)

Humulin R cartridges contain fast-acting insulin for managing blood sugar in diabetes. Used with an insulin pen, they help control blood glucose levels before meals. Insert the cartridge into the pen, prime, set the dose, and inject subcutaneously. Humulin R starts working within 30 minutes and lasts about 4-6 hours. Store as instructed and use a new needle for each injection.
