Whenever possible, take your unused prescription drugs to a collection program or event – the Wisconsin Department of Justice’s DRUG TAKE BACK Days happen, at minimum, in the spring and fall of each year. You may safely dispose of controlled and uncontrolled substances, over-the-counter medications, ointments, patches, creams, non-aerosol sprays, vials, and pet medications at these events. If your prescriptions contain narcotics or other controlled substances, contact your local police department to find out if the police will accept them. Some police departments will accept non-controlled substances too, but you should be sure exactly what yours will accept before dropping off items.
