Managing unwanted pharmaceuticals

Unused drugs kept in medicine cabinets, tossed in the garbage, or flushed down the toilet or drain can be serious threats to human and environmental health. In one recent national study, scientists analyzed streams for 95 different organic wastewater contaminants, including pharmaceutical compounds. One or more of these wastewater contaminants appeared in 80 percent of the streams. Risks posed to aquatic organisms by long-term exposure to various pharmaceutical compounds are unknown. Wastewater treatment plants and septic systems usually do not treat or only partially treat pharmaceuticals, so chemical compounds from pharmaceuticals pass through treatment plants or septic systems to rivers or groundwater.

Drugs of concern include controlled and non-controlled prescription drugs, as well as over-the-counter medications. Proper management of these drugs reduces avoidable poisoning of both children and adults; prevents intentional misuse of unwanted prescription drugs, especially by teenagers; and protects water quality and fish.

Disposal recommendations for household pharmaceuticals


  • Dispose of pharmaceuticals down a drain or toilet.
