EVRA’s product information now includes average daily release rates for norelgestromin (200 micrograms every 24 hours) and ethinyl estradiol (35 micrograms every 24 hours). This information replaces the previously labeled daily delivery rate of norelgestromin (150 micrograms every 24 hours) and ethinyl estradiol (20 micrograms every 24 hours). The term “release rate” has also replaced the prevous term “delivery rate” as a more descriptive term regarding release of hormones from the patch.

The new data was derived by measuring the hormone content that remained in the EVRA patches worn by women for 7 days. The previously labeled delivery rate information was estimated using a different method. The company reports that there has been no change to the way the patch is made, and there is no known impact on the safety and effectiveness of the patch as a result of the new information on the average daily release rate.

In November 2006, Health Canada issued a letter to health care professionals warning of the risk of venous thromboembolism in users of Ortho Evra and expressed that the same warning should apply to EVRA. Studies have found that the patches can leak too much medicine into the blood stream, causing blood clots that can lead to strokes and even death.

To date, more than 500 lawsuits have been filed on behalf of women who suffered blood clots and other serious side effects from taking Ortho Evra. Recently, drug maker Johnson & Johnson settled lawsuits with Canadian women harmed by the birth control patch.

The Ortho Evra patch was originally marketing to young women who were turned off by the notion of taking a once-daily pill for contraception. The patch is replaced after a week. However, the patch was found in some cases to seep too much estrogen into the bloodstream, which can cause serious health problems.

As an emerging pattern of young women suffering from pulmonary embolisms and strokes emerged, health experts began to point fingers at Johnson & Johnson. Despite the settlements in both the U.S. and Canada, the patch is still on the market and doctors are still prescribing it.

Ortho Evra was first approved for marketing and sale in Canada in 2002. Since then, at least 16 cases of blood clots and one heart attack among women who were using the patch have been reported. Two patients died, including a 16-year-old girl, according to Health Canada.

The Canadian lawsuits involve 22 women from Ontario, British Columbia and Quebec; however, anyone else with a valid claim can still come forward and be included in the settlement. The Canadian plaintiffs sought C$400,00 each in compensation and C$20 million in punitive damages.

The lawsuit claims that Johnson & Johnson failed to properly warn patients and doctors that its Ortho Evra contraceptive patch has a higher risk of blood clots, strokes and heart attacks compared to the birth control pill.

An Ontario judge will be asked to end the suit at a hearing March 23.
