Bring Unwanted Medications to MedDropSA on Saturday, Feb. 2

Got unwanted or expired medications? Bring them to MedDropSA on Saturday, February 2, for free, safe disposal!

When Saturday, Feb. 2
8 a.m. – 1 p.m.
Where City of San Antonio South Central Service Center
4719 S. Zarzamora

MedDropSA provides a convenient alternative to safely dispose of unused or out-of-date pharmaceuticals at no cost to residents. The collection event will take place at the City of San Antonio’s Household Hazardous Waste (HHW) Mobile Collection Event:

Residents with expired or unwanted medications can simply drive through the City’s HHW Mobile Collection Event and drop off medicines along with any other household hazardous waste. San Antonio Police Department officers will collect the medications. We will not be able to accept needles or ‘sharps.’

To bring medicines to the event, please dump pills into a plastic Ziploc bag.

There are no residency requirements to drop off private-use prescription or other medications for MedDropSA. However, to drop off HHW items, you must be a City of San Antonio resident and bring a recent CPS Energy bill showing that you are a solid waste ratepayer.

Since the first MedDropSA event in December 2009, 8,300 pounds of drugs have been turned in for free, safe disposal. Having a safe, convenient alternate disposal method keeps prescription and over-the-counter medications out of the environment and out of the hands of those who might abuse them. For more information, visit MedDropSA's website.

MedDropSA is sponsored by San Antonio Water System, the San Antonio Police Department and the City of San Antonio. In addition, several local partners are helping to promote MedDropSA:

  • Alamo Area Council of Governments
  • Bexar County Medical Society
  • CPS Energy
  • H-E-B
  • Home Instead Senior Care
  • Reliant Home Health
  • Restorative Health Care
  • San Antonio River Authority
  • SeniorBridge
  • U.I.W. Feik School of Pharmacy
  • UTSA College of Sciences
