Women with diabetes are strongly advised to achieve good glucose control before they become pregnant in order to minimize the chances of birth defects and miscarriage. Those who use birth control methods now have a new choice.

FDA has approved the first skin patch for birth control. The weekly patch releases hormones through the skin into the bloodstream to prevent pregnancy. It is a 1.75-inch square that should be applied to the lower abdomen, buttocks or upper body. The woman wears each patch for one week and then replaces it with a new patch for three weeks out of the month. The fourth week is patch-free, allowing a woman to have her menstrual period, similar to the regimen for birth control pills.

The patch is similar to birth control pills in its effectiveness and its risks, including an increased risk of blood clots, heart attack and stroke. In clinical trials, the patch appeared to be less effective in women weighing more than 198 pounds.
