Thimerosal Flu Vaccines are "Hazardous Waste"
Guidance for disposing unused vials not administered to patients.
Pharmacy Times Unused Medication Vial Disposal Guide
Unused medication vials. Always check with your supplier to see which, if any, of the unused vaccine can be returned. If the vials cannot be returned, disposal options must be determined based on the following vaccine delivery method:
Preservative-containing vaccines. If unused vaccine vials or syringes are expired or subject to recall, it must be determined whether the
vaccine exceeds the maximum concentration (0.2 mg/L) for the toxicity characteristic for mercury per federal law.
Look for 0.01% thimerosal.
These vaccines must be disposed of as hazardous waste
if the concentration is >0.2mg/L, or as medical waste destined for incineration if it is <0.2mg/L.7
Preservative-free live attenuated vaccines. Used vials should go into the sharps container. If they are expired or recalled, and remain in their original packaging, they may be sent for incineration with your medical waste disposal company.6
Preservative-free non-live attenuated vaccines. Your medical waste disposal company may be able to take the expired drugs for incineration. Check with your state as some states may allow these vaccines to be placed into the trash, even though this is not considered a best-management practice.6
