When using injectable treatments, it’s important that you safely discard them in a sharps bin. Not doing so increases the risk of infection and injury.
Learn how to safely discard needles and what to do with a full sharps bin.

Summary:
When using injectable treatments, you should dispose of them correctly in a sharps bin. These bins are specially designed to help you discard sharp medical objects, like needles, syringes, and scalpels safely.
The bins are made from a thick plastic material that sharp items can’t easily pierce. It has a secure lid to ensure that nothing spills out once placed inside. The bins are typically bright yellow with a biohazard symbol to alert others that they contain hazardous material.
It’s important to dispose of needles properly to lower the risk of infections and injury. Each used injection carries the risk of blood-borne infections, such as HIV and Hepatitis C, as well as bacterial and fungal infections.
Anything sharp can go into a sharps bin, including:

To use a sharps bin:
You should write the following information on the label outside the container:
After the bin is full and locked, dispose of it safely. Make sure there’s no blood or liquid outside the bin and it’s clean.
Treated will send you a free sharp bin when you buy the following treatments:
We send a yellow SharpsGuard 1 litre sharps bin, which should last a little under a year for weekly injections. But if you finish one sooner, don’t worry. Just message us and we’ll send a new one with your next order.
When the bin is three-quarters full, stop using it to ensure nothing spills out. At this point, you should lock it securely and dispose of it. Overfilling the bin increases your risk of injury as the sharp items can potentially poke through the opening.
When your sharps bin is full, please message your clinician to request a new one. We’ll send a replacement free of charge, and it should arrive by the next working day. It’s best to request a new bin before your current one is completely full, in case delivery is delayed.
You can dispose of a sharp bin at the following places:
Before dropping your bin off, it’s best to phone ahead to check they’re able to provide this service for you (not everywhere does).
Disposing of sharps bins safely reduces the risk of infection and injury. Sharps bins contain clinical waste, which requires specialised waste removal services. Putting them in a normal household bin increases injury risk for people handling them and becomes an environmental hazard.
Most pharmacies dispose of sharps bins, but it’s best to call and confirm before heading out to them. The service is free and shouldn’t take much time.
