Estrogen patch
From Wikipedia, the free encyclopedia
The estrogen patch is a delivery system for estradiol used as hormone replacement therapy to treat the symptoms of menopause, such as hot flashes and vaginal dryness, and to prevent osteoporosis. The estrogen is given transdermally rather than in the standard oral tablets, meaning that the estrogen patch carries some similar risks and benefits as more conventional forms of estrogen-only hormone replacement therapy, but there are also important differences. For example, transdermal estrogen bypasses the liver so avoids the liver effects that occur with use of oral medications, and has slightly different effects on triglycerides and cholesterol than oral estrogens.
[edit] Administration
Applied to fatty areas of the skin, preferably the lower abdomen or buttocks (never breasts!) twice weekly or weekly, depending on the brand.
