Chemical waste

Important – Learn about the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). GHS-compliant labels that include a harmonized signal word, pictogram, and hazard and precaution statements for each hazard class and category will begin to appear in our chemical inventories soon.

Controlled substances

While controlled substances (CS) are not "hazardous" waste, disposal of CS is strictly regulated by federal law.

Note: See Pharmaceuticals Disposal if you need to dispose of a non-CS pharmaceutical.

Drain disposal

Do not dispose of personal waste pharmaceuticals (medications) down the drain or down the toilet. This includes any prescription or nonprescription substances intended to be swallowed, inhaled, injected, applied to the skin or eyes, or otherwise absorbed.

Household hazardous waste

Over-the-counter medicines

Disposing of over-the-counter medicine (OTC) is easy. Many community-based pharmacy “take-back” programs offer the best option; otherwise, almost all OTC medicines can be disposed of in the household trash. Consumers should take precautions, however, by reading the label to ensure OTC medicines can be disposed of in the trash. Follow these guidelines:

Note: Wastewater treatment plants are not designed to remove pharmaceuticals and studies show exposure to even low levels of drugs has negative effects on fish and other aquatic species, and also may negatively affect human health. Households are advised to not dispose of waste medication down the drain or down the toilet. This includes any prescription or nonprescription substances intended to be swallowed, inhaled, injected, applied to the skin or eyes, or otherwise absorbed.
