Police add Drug Take-Back Drop Box at City Hall
The O'Fallon Police Department has added a Prescription Drug Take-Back Drop Box for all residents. The drop box provides a safe and free way to discard old or unused medications and keep them out of the hands of those who may abuse them.

All residents need to do is drop off their unused or expired prescription medications in the lobby of the O'Fallon Police Department Monday through Friday 8 a.m.-4:30 p.m. The drop box is designed to handle small, residential quantities of old prescriptions and cannot handle sharps or hazardous materials. Please contact Sgt. Robert Kendall at 636-379-5680 with any questions.
