When the clinic prescribed the continuous bespoke progesterone at my first consultation I was terrified. I have had such a bad experience with Utrogestan (which is designed for pregnancy) and synthetic progesterone I really did not believe that bespoke 50mg progesterone would be any different. I voiced my extreme concerns to the doctor and she assured me that my experience would be different this time because the dose is lower and the progesterone is absorbed buccally ie between the lip and the gum. She pointed out that when progesterone is absorbed buccally it behaves differently and more like the progesterone you used to produce yourself and it actually complements oestrogen. Very importantly, it prevents oestrogen spikes and acts like a hormone stabiliser.
The information in bold is exactly the sort of misinformation - or rather misleading comments by doctors at these specialist clinics that led to the medical establishment and menopause societies voicing such concern not so long ago about BHRT.
The point is the doctor is comparing buccal with oral administration - and therefore what she is saying is indeed true (they behave differently), but any method that absorbs progesterone directly into the bloodstream is getting it into your body so that it behaves like our own progesterone ie vaginal also. These clinics are conning women (because they are private and expensive!) if they state otherwise (not you Mary G as you are knowledgeable) - but it is not necessary to have buccal administration to be able to have bio- or body-identical progesterone.
Moreover, actually, even though the liver first pass effect is avoided through buccal or vaginal dosing (progesterone is absorbed straight into the bloodstream), I imagine buccal delivery is still less effective at a given dose for example than vaginal delivery ( but better than oral ingestion) because systemic concentrations must still be high enough for sufficient to reach the endometrium. With vaginal delivery (in my view the best option currently available) the progesterone is transported and absorbed directly through the cervix to the uterine tissues. One paper I read suggested it was ?held? there for longer than any other method. Buccal delivery also produces a rapid rise in serum concentration within about 80 mins (according to paper I read) which might be unacceptable for some women even though the dose is lower.
Also - a 50 mg dose even used vaginally would only be beneficial for women on low doses of oestrogen due to the need for endometrial protection. Studies show that the current licensed doses work best at low and medium oestrogen doses - and tend to cause more bleeding at higher oestrogen doses (can't recall the papers that looked at higher doses).
Sustained release would definitely be brilliant - if such a vaginal capsule could be produced but failing that using the current capsules vaginally are the best we can get at the moment.
Hi MaryG - What I don't quite understand is why a compounded 50mg progesterone dose works so much better than using Utrogestan 100mg every other day.
Is it the carrier ingredient in Utrogestan that causes so many of us such problems perhaps? Or method of delivery? If its all micronized progesterone then it has to be something like that surely? I could quite understand it if that was the case because I have to take antihistamine daily and tolerate one particular 'brand' a lot better than other brands, and some give me very unpleasant side effects.
What is the compounded tablet like?
Stellajane when used orally it is the metabolic by-products (after going through the liver) that causes most of the negative side effects, but additionally these same compounds as well as progesterone itself directly cause the side effects - the pronounced sedative effect for example - is a property of progesterone. Nothing to do with the carrier ingredients. Remember when you were pregnant - the fatigue and exhaustion especially during the first trimester?!
Personally I would not want to take progesterone daily at any dose - because there are still question marks about its effect on the breast, so being a long term HRT user I would rather put up with the bleed and the effects of the prog, unpalatable though these are.
