Blood clots, deaths linked to Evra

From the (University of Western Ontario) Gazette:
The Evra birth control patch may be more convenient than the pill for many Canadian women, but new evidence suggests it may also be more dangerous.

The January issue of Health Canada’s Canadian Adverse Reaction Newsletter documented 16 cases of blood clots and one heart attack in Evra patch users since its arrival on the Canadian market in 2004. Two of the 17 patients reported to Health Canada died as a result.

One documented case of death was that of a 16-year-old, and most of the 93 total adverse reactions Health Canada received were from women in their teens, 20s or early 30s.

The Evra patch, manufactured by Janssen-Ortho Inc., is a prescription-only contraception patch that adheres to the skin, delivering hormones into a woman’s body to prevent pregnancy.

According to IMS Health Canada, a market research company, between January and November 2007, 274,617 Evra prescriptions were dispensed from retail pharmacies.
