Indications 

Estraderm Patch is a prescribed medication for women to alleviate menopausal symptoms like hot flashes and vaginal dryness resulting from decreased estrogen production in the body.  

Furthermore, Estraderm Patch is prescribed to women experiencing insufficient estrogen production, often associated with conditions like hypogonadism, primary ovarian failure, as well as for the prevention of postmenopausal osteoporosis. 

As a hormone replacement therapy (HRT), Estraderm Patch contains estradiol, which is designed to substitute the body’s natural estrogen production. 

Uses and Dosage 

Before using Estraderm Patch and with each prescription refill, carefully review the accompanying medication guide and patient information leaflet. Seek guidance from your doctor or pharmacist if you have any queries or need additional information. 

Estraderm Patch is designed to be placed on the skin and should be replaced twice weekly. 

The prescribed dosage of this patch may vary per individual based on their medical conditions and response to the treatment. 

For proper Estraderm Patch application, follow these steps: 

1. Remove the protective pouch of the patch. 
   • Tear it open at the indentation (without using scissors) and remove the patch.  
   • Note that bubbles on the patch are normal. 
2. The adhesive side of the patch, which is the side to be applied to your skin, is covered by a stiff protective liner. Remove this liner by sliding it sideways between your thumb and index finger, holding the patch at one edge.  
   • Discard the protective liner and avoid touching the adhesive. 
3. Apply the patch immediately (after opening the pouch and removing the protective liner) to a clean, dry area on the trunk of your body (including the buttocks and abdomen).  
   • Ensure the chosen site is not exposed to direct sunlight.  
   • Rotate application sites with at least a one-week interval and choose non-oily, undamaged, and non-irritated areas.  
   • Avoid the waistline to prevent rubbing from tight clothing. 
4. Press the patch firmly in place with your palm for approximately 10 seconds, ensuring good contact. 
5. Replace the patch twice weekly.  
   • Estraderm Patch includes a calendar checklist for scheduling. Mark the two days of the week when you plan to change the patch, and always adhere to this schedule. 
6. When changing the patch, remove the used patch and dispose of it.  
   • Any residual adhesive on your skin can be easily rubbed off.  
   • Place the new patch on a different skin site, making sure not to use the same area for at least one week after removal. 

Exposure to water during bathing, swimming, or showering will not impact the patch. If, by chance, a patch comes off, reapply the same patch and maintain your initial treatment schedule. If needed, you may use a new patch while still following your original schedule. 

To achieve the best results, follow the prescribed usage of the Estraderm Patch precisely. If your condition persists or deteriorates, notify your doctor.
