An estrogen patch is a transdermal delivery system that releases hormones, primarily estradiol, directly through the skin into the bloodstream. This method offers a steady, consistent supply of hormones throughout the day, beneficial for managing conditions like menopause symptoms. Unlike oral hormone therapies, patches bypass the liver, potentially reducing risks and promoting more stable hormone levels.
Recommended Patch Placement
Selecting the correct application site is important for optimal hormone absorption and to minimize skin irritation. Patches are typically placed on clean, dry, and hairless areas of the lower abdomen, upper outer buttocks, or upper outer thigh. These locations have sufficient subcutaneous fat, aiding steady hormone absorption. They also experience less movement and friction from clothing, helping the patch remain secure. Some studies suggest that absorption may be more effective when patches are applied to the buttocks or thighs compared to the abdomen.
Avoid placing the patch on breasts, the waistline, or skin folds, as these sites can lead to inconsistent absorption or dislodgement. Do not apply the patch to oily, broken, burned, or irritated skin, nor over birthmarks or tattoos, as these conditions affect adhesion and absorption.
Applying Your Estrogen Patch
Proper application ensures effectiveness and maintains skin health. Begin by washing and thoroughly drying your hands and the chosen site. Ensure the skin is free of lotions, oils, powders, or residues that could interfere with adhesion. Avoid applying to freshly shaved areas, as this can lead to irritation.
Carefully tear open the patch pouch, avoiding scissors. Peel off the protective backing, being careful not to touch the adhesive side. Once positioned, firmly press the patch down with your palm for 10 to 15 seconds. This pressure creates good contact, securing the patch in place. Most patches stay on during bathing or swimming; avoid vigorous scrubbing directly over them.
Rotating Application Sites
Rotating application sites with each new patch ensures consistent hormone delivery and prevents skin irritation. Repeatedly applying to the same spot can cause redness, itching, or decreased absorption, sometimes called “tissue exhaustion.” To maintain optimal absorption and minimize discomfort, select a different area within the recommended zones.
Alternating between the left and right sides of the lower abdomen or buttocks can be helpful. After removing a patch, allow the skin to recover for at least one week before reapplying to the exact same spot. This rotation ensures the skin remains healthy and receptive.
Patch Care and Disposal
Patch change frequency depends on the brand and prescription, typically once or twice a week. Follow the prescribed schedule to maintain steady hormone levels. If a patch detaches prematurely, reapply it if it still adheres, or apply a new patch to a different site. Continue your original schedule for the next patch change.
Proper disposal of used patches is important for safety and the environment. After removing a used patch, fold it in half so adhesive sides stick together. This prevents residual medication contact. Dispose of the folded patch safely in household trash, out of reach of children and pets. Never flush used patches down the toilet, as this introduces hormones into the water system.
