避孕貼片
避孕貼片與一塊標識牌相似，約有5釐米(7.75英寸)見方，被貼在肩背部、下腹部或軀幹（除乳房外）上。在這些部位，它持續釋放孕激素和雌激素，通過皮膚吸收進入血液迴圈。既然這種吸收激素的方式繞過了消化道，它是一種受到有胃腸功能症狀的女性歡迎的避孕方式。貼片的有效期為一周，此後在總數三周的時間裏得更換兩次。緊隨著的第四周為“貼片空閒期”（不需要貼貼片時間——譯者注），為行經期。其後，又連續地使用三周貼片，與此類推。多數情況下，每週更換一張貼片比每日吃一粒避孕藥要方便得多。不過，避孕貼片可能的副作用與避孕藥相同，既不是所有的女性都能夠用-也不是所有的婦女所應該用的方法。遵照醫囑和在醫生的監察下使用是必要的。

Contraceptive Patch
The contraceptive patch is similar to a band aid. It is a square patch of ca. 5 cm (1.75 inch) placed on the shoulder, the lower abdomen or the torso (excluding the breasts) where it continuously releases progestin and estrogen through the skin into the blood stream. Since this bypasses the digestive tract, it is a welcome method for women who have stomach problems. The patch is effective for one week, after which it has to be replaced twice for a total of three weeks. This is followed by a fourth “patch-free” week to allow for the woman’s menstrual period. Thereafter, the patches are applied again for three weeks in a row etc. In many ways, changing a patch one a week is more practical than taking a pill every day. However, the possible side effects of the patch are the same as that of the pill, and not all women can or should use either. A doctor’s advice and supervision are essential.
Effectiveness: Very effective |
