I Have Been Using The ClimaraPro Transdermal Patch For Hot

I have been using the ClimaraPro transdermal patch for hot flashes and other symptoms of menopause for several years. The ClimaraPro patch is not covered by my drug plan and is very expensive so I was thinking about changing to the generic estradiol patch instead which is more in my price range and my drug plan helps pay for it. The difference between the patches is the ClimaraPro patch has 2 ingredients (estradiol & levonorgestral) and the generic patch only has one ingredient (estradiol). I still have my ovaries and all so I was wondering if I could just use the generic patch instead of the more expensive ClimaraPro patch. Thanks.
