Transdermal patches were introduced in the 1990s initially for birth control, as a treatment for angina or heart failure, and for smoking cessation. Today, drug patches have branched out to other approved therapies including neurology, pain management and urology and some, like the nicotine patch, are now available over the counter as well.

Patches offer an alternative delivery system that may benefit some consumers. For example, the Ortho Evra birth control patch is marketed to younger women who would rather wear the patch that is changed weekly instead of taking a daily pill. However the delivery system of some patches have raised serious questions about their safety.

In January, we told you about Johnson & Johnson recalling its Duragesic fentanyl pain patch – the fifth recall of the pain patches since 1994 – because it leaked too much medicine into the bloodstream, making it highly addictive and resulting in deaths. The same company’s birth control patch, Ortho Evra, has also been blamed for leaking too much medicine into the bloodstream leading to pulmonary embolisms and strokes. The company already has settled several lawsuits charging that its Ortho Evra birth control patch has caused serious harm and even death.

Pharma Live says the demand for prescription drug patches is on the rise, especially among the elderly who may forget to take medications and may benefit from the patch system. Let’s hope the serious injuries caused by such patches don’t rise as well.

This is the fifth recall of Duragesic fentanyl patch since 1994. Patches have caused much pain for Johnson & Johnson. Last year, the company paid $68 million to settle lawsuits against the company’s birth control patch, Ortho Evra. The patch was linked to at least 40 deaths caused by blood clots.

Ortho Evra was originally marketed to women seeking an alternative to a one-daily birth control pill. The patch system was designed to deliver the same level of estrogen as the birth control pill, but its delivery system was different. Pills are taken orally and are processed through the liver before reaching the blood stream. The medication on the patch is applied directly to the skin and is not diffused by the body before reaching the blood stream. In contrast to the birth control pill, the patch delivers 60 percent more estrogen to the patch-wearer’s blood system. And that, according to the numerous lawsuits filed, is where the problems begin.

Despite an emerging pattern of young women suffering from pulmonary embolisms and strokes, Johnson & Johnson continued to market the patch, running advertisements that at times did not include warnings of serious, life-threatening side effects.

While Johnson & Johnson no longer markets Ortho Evra, the birth control patch is still available and has yet to be pulled from the market.
