Never throw away or flush expired and unused pharmaceuticals.
Contact Drug Services at the drug services webpage for the current approved vendor for disposal of DEA Sch. II-V drugs (controlled substances).
All other pharmaceuticals must be disposed of as hazardous waste. For information on hazardous waste collection at the UW, please see the hazardous chemical waste webpage.
The state of Washington has classified all expired and unwanted pharmaceuticals, including "over the counter" drugs, as Dangerous Waste.
For more general information about how and why we manage pharmaceuticals as hazardous waste, go to the Washington State Department of Ecology's pharmaceuticals website.
