Yes. Elestrin is generally considered a bioidentical hormone therapy because its active ingredient is 17β-estradiol, which has the same chemical structure as the estradiol naturally produced by the human ovaries. The FDA labeling identifies Elestrin’s active ingredient as estradiol (17β-estradiol).
The term “bioidentical” does not mean risk-free or necessarily “natural.” Elestrin is an FDA-approved prescription medication manufactured to provide estradiol in a standardized dose. It carries the same important estrogen-related warnings and precautions as other systemic estrogen therapies.
So, in short: Elestrin = bioidentical estradiol delivered through the skin as a gel.
