The Medsaway ContraPatch from Verde Environmental Technologies is a new medication disposal system for prescription transdermal patches. Used transdermal patches can contain up to 95% excess active pharmaceutical ingredient, posing safety, abuse, and environmental contamination risks. This system deactivates the remaining medications in used patches via chemical binding with a proprietary activated carbon system. By deactivating and containing potentially dangerous medications, the system provides increased safety and security from diversion. The product can be disposed of in a landfill where the insoluble products will not leach into groundwater. The ContraPatch is environmentally responsible, inexpensive, safe, and convenient, and may be used with any medications that do not have specific disposal instructions.
