The B-12 patchs, made by global nutraceticals company VitaSciences, are sold as an alternative to oral supplements and shots. The company has applied for a patent on the patch and mentions on its Web site a clinical study involving six volunteers. Each patch contains 1,000 micrograms of vitamin B-12 and is designed to be worn once a week for no more than 24 hours. The dime-sized patches are worn on the neck behind the earlobe.

The patches deliver nutrients into the circulatory system by absorption through the skin. A special membrane controls the rate at which the nutrients are absorbed, allowing the active ingredient to release at a consistent rate over a period of time.

But can that delivery system be trusted? Other patch-delivery systems have come under scrutiny lately for seeping too much of the active ingredient into the blood stream. Drug maker Johnson & Johnson has settled numerous lawsuits in both the United States and Canada over its contraceptive patch Ortho Evra. The patch was found to leak too much estrogen into the blood stream causing blood clots which led to strokes and even death in some women.

Earlier this year the company’s pain patch, Druagesic fentanyl, was recalled for leaking too much medicine into some people who used them. That overdosing caused addictions and deaths in some users. While the fentanyl patch has been recalled, Ortho Evra is still widely available for use as birth control.

Vitamin B-12 toxicity, or having too much vitamin B-12 in your system, is uncommon but can have serious side effects. Side effects of vitamin B-12 toxicity include diarrhea, feeling of swelling over the entire body, blood clots in the legs and signs of an allergic reaction such as hives or rash; itching; swelling of the lips, mouth or throat; wheezing or other difficulty breathing.

The B-12 patch is still in a testing phase, and there don’t seem to be any reports so far of adverse reactions, but it is important to be aware of possible dangers based on experience from this type of delivery method. Those who suspect vitamin B-12 toxicity should consult a medical professional.

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 Plan First! program is an outreach by the Wayne County Department of Public Health and targets low-income women between the ages of 19 and 44 who are U.S. citizens or qualified legal residents, are not currently pregnant and are not covered by Medicaid or other family planning coverage.

The Plan First! program offers a wide variety of women’s health services such as office visits, pap tests, breast exams, lab tests, medications, treatment of sexually transmitted diseases and sterilization referrals. It also provides women with birth control options such as the pill, the Ortho Evra contraceptive patch, condoms, vaginal contraceptive ring, spermicide, barrier method and natural family planning.

With birth control costing consumers as much as $50 a month, many low income women may choose to go without it and take their chances with an unwanted pregnancy.

“In today’s environment, higher education and a stabilizing career have become even more important to women and families,” said a spokesperson with the health department. “Controlling the timing of a pregnancy is one of the keys to a bright and promising future.”

However, women should carefully consider birth control methods before choosing one that’s right for them. While convenience and personal beliefs weigh heavy on a decision, so should the safety of the product. Birth control pills come with a sight risk of blood clots, but research has shown that the birth control patch, sold under the brandname Ortho Evra, carries a greater risk of serious health problems, such as blood clots that have lead to stroke and even death in young women.

While contraceptive patch maker Johnson & Johnson has shelled out millions to settle lawsuits from women who were injured by the patches both in the United States and Canada, the drug is still available on the market and prescribed to women.

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.
