An HRT patch, also called transdermal therapy, is worn continuously and applied to the upper buttocks, back or thigh area. The patch is replaced once or twice a week. It delivers hormones through the skin into the bloodstream. The dose is normally lower than with a pill since the hormones do not have to enter the stomach to reach the bloodstream.
The patch should be applied to dry skin, and powder or lotions should not be applied to the location where the patch will be placed because they may create a barrier for hormones to be released into the body. - The HRT patch carries with it side effects such as skin irritation where the patch is applied, nausea, bloating, breast soreness, headaches and moodiness. Other side effects include irregular bleeding. Side effects may subside after six to eight weeks.
