(WOAI.com) SAN ANTONIO — Controversy is brewing over a patch used for pain relief. At least two people in San Antonio have died after using the Fentanyl patch, and their families are blaming what they say is a defect.

Like most medicinal patches, Fentanyl is used by peeling off a sticky side and placing it against the skin of a patient. The patch is left on the skin for up to 72 hours and is supposed to provide the exact amount of medication needed.

However, the families of two San Antonio women who died say the patch they were prescribed to relieve their pain ended up killing them.

According to lawsuits filed by family members, both women suffered chronic pain. So, their doctors suggested Fentanyl patches.

Fentanyl is stronger than morphine. When it is applied to the skin, it then delivers a certain amount of Fentanyl into the patient.

While wearing the patches, Donna Singleton and Ellen Burks died. Their families say both suffered an overdose of Fentanyl because the patches were defective.

Similar patches have been recalled before because a cut along the side of the patch allowed too much Fentanyl to leak and cause a possible overdose.

Wait a minute, didn’t the Food & Drug Administration approve the use of these Fentanyl patches?  Why, doesn’t that mean it’s safe?  We know for sure that the FDA wouldn’t let people stick a patch on their body loaded with a Schedule II drug if it weren’t safe, even if this Fentanyl is just one isomer short of being Schedule I “China White” heroin.

We know this because they protect us from that evil Schedule I medical marijuana that never killed anybody in 5,000 years.
