Donna’s Question: 

Hello. I’m 62 years old with a uterus. Recently my nurse practitioner switched me from 6% progesterone cream to Prometrium capsules. The amount of cream I was using was 1/4 teaspoon two weeks out of the month. She also added in the Intrarosa vaginal inserts instead of the estradiol cream for vaginal discomfort. I do not have many symptoms other than occasional sleepless nights and occasional hot flashes. My question is are the Prometrium capsules safe? And is the cream safer than the capsules? Thank you, Donna.

Short Answer:

Both Prometrium and bioidentical progesterone are safe to take. However, many women do not seem to tolerate Prometrium very well. Prometrium is instant release, which seems to make it less tolerable for some women. In most cases, we prefer to us sustained-release progesterone, which is typically better tolerated by most women. This is important for women taking estrogen who still have a uterus. Estrogen causes the uterine lining to thicking and oral progesterone inhibits this thickening. Progesterone cream does not inhibit the growth of the uterine lining, which is why we prefer to prescribe oral progesterone for our patients.
