Can I put Climara patch on thighs?

Climara is transdermal patch with hormonal therapy, there are some area that should be avoided eg. breast and genitalia. The best places to stick the patch are buttocks and lower abdomen, Stick it somewhere else may alter the amount of hormone you need for your treatment. You can ask your IVF doctor whether it is Okay or not but I suggest you to stick with the prescription.
