Cold/flu remedies
Birth control pills
Hormone replacement drugs
Veterinary medicines
Codeine, phenobarbital, and anabolic steroids, narcotics, tranquilizers, etc

Why is this important?

Medications flushed down the toilet or in drains pass through the sewer system and eventually enter our streams, lakes, and rivers. Medicines and synthetic hormones have been detected in trace amounts in bodies of water. This could lead to increased bacterial resistance to antibiotics and interference with growth and reproduction in aquatic organisms such as fish, frogs and all marine life.

The presence of medications in the environment is a complex issue and the risk to humans and the environment is still being determined. With tens of thousands of medicinal products on the market and more being developed each year, the long-term risks have not been determined on the effects on the environment. However, in order to minimize the potential negative and irreversible impacts, it is important that we limit the disposal of waste medications to the sewer.
