How should I dispose of insulin pump cartridge needles?

Varies by location. Laws for safe needle disposal vary by state, county, or city. Check with your diabetes educator or doctor. You can also google "needle disposal" followed by your state/city. Basically, dispose of these needles the same way you would dispose of syringes.
