Thank you for your inquiry.
The FDA website has information regarding disposal of Sharps. You will see pictures there of automatic epinephrine injectors which are considered Sharps, no different than the needles you use in your office. Automatic epinephrine injectors, regardless of type, are disposed of in the same manner as all other medical Sharps. One would not attempt to remove a battery from these devices as one would not attempt to dismantle any Sharps. Patients should be advised to take used injectors to a location, such as their physicians office, which has Sharps disposal capabilities.
Thank you again for your inquiry and we hope this response is helpful to you.
