What are sharps?

"Sharps" refer to medical objects with sharp points or edges, such as needles, syringes, lancets, and infusion sets, that can cut or puncture the skin and transmit disease if not handled properly.

⚠️ Sharps should never be thrown in the regular trash or recycling bin, as improper disposal can pose serious risks to sanitation workers, pets, children, and the environment.

The safest and most recommended way to dispose of used insulin needles and syringes is to place them in an medically-approved sharps container. These containers are puncture-proof and leak-resistant.

2. Unscrew or detach the needle or infusion set.

3. Place it immediately into the container — do not bend, break, or clip the needle.

4. When the container is full, seal it securely.

5. Take it to a local pharmacy, clinic, or medical waste drop-off site for safe disposal.

What if you don't have a sharps container

Make sure to:

• Label the container clearly as "hazardous medical waste"
