Pharmaceutical Disposal Program


Central San developed its Pharmaceutical Disposal Program by partnering with the Sheriff’s Department and eight local police departments in central Contra Costa County. Households may use any of the collection sites to safely dispose of unwanted or expired medications. These sites are open to all county residents Monday through Friday, from 8:00 a.m. to 5:00 p.m.

Disposal of pharmaceuticals down a toilet or drain has become a serious public concern. Either method can allow medications to make their way into regional water sources by passing through wastewater treatment plants. The drop-off program can alleviate some of that pollution. Other reasons for the program include preventing abuse by young adults and to protect seniors. This disposal option decreases the likelihood of anyone taking a wrong or outdated medication by mistake, and gives families a convenient place to dispose of unwanted medicines.

For more information or to find a drop-off location near you, please refer to our printable Pharmaceutical Disposal Brochure.
