Pathogens in pharmaceutical waste may enter the human body by a number of routes:
- through a puncture, abrasion, or cut in the skin
- through the mucous membranes
- by inhalation
- by ingestion
Improperly disposing of pharmaceutical waste can harm the environment and can contaminate drinking water. Poisoning can occur through direct contact with the product, inhalation of vapors, drinking contaminated water, or eating contaminated food. Other hazards may include the possibility of fire and contamination as a result of inadequate disposal such as burning or burying. Visit the DEA’s page for proper disposal information.
Lastly, chemical residues discharged into the sewerage system may have adverse effects on the operation of biological sewage treatment plants or toxic effects on the natural ecosystems of receiving waters. Similar problems may be caused by pharmaceutical waste (i.e. antibiotics and other drugs, heavy metals such as mercury, phenols, and derivatives, and disinfectants and antiseptics).
