I moved back to the UK from Canada recently. My GP in Canada had prescribed me 100mg daily progesterone plus two pumps estrogen gel. Initially the GP prescribed cyclical 100mg progesterone for three months before adding in the estrogen.
Before starting HRT my periods had been very irregular - I had about 5 months with no period, then bleeding roughly every two weeks for about two months ish, then no period for a few months then the frequent bleeding again. This was one of the reasons I saw the GP about HRT. When I started 100mg progesterone I didn't have any bleeding/periods for about 5 months, and then did have some irregular bleeding over a approx 2 to 3 months but not as disruptive or frequent as the bleeding prior to progesterone.
The estrogen helped with night sweats and I was generally happy with this HRT regimen.
I get migraines and headaches and found the HRT helped with this to a degree - the migraines didn't increase at least. There are other stressors and triggers for my migraines as well and they didn't necessarily track with menstrual cycles pre HRT.
I am nearly 50 and started the HRT at 48 and had been taking the 100mg progesterone for over 1 year before I moved back to the UK.
When I saw my new GP practice in the UK to request the HRT prescription the doctor told me I had to switch from continuous daily 100mg progesterone plus two pumps estrogen gel to 200mg cyclical progesterone (plus estrogen gel as before - no issues there) because this is NHS prescribing guidelines. This GP didn't seem to know very much about HRT/perimenopause and just said this was what was on the screen for prescribing HRT - it felt very much like a computer says no response.
The first cycle during the progesterone pause for the withdrawal bleed I had a migraine and then on and off headaches that were very disruptive. I also had very high anxiety and low mood - I've never had particularly bad PMS symptoms before so this was very distressing and quite alarming. I'm still in the pause between starting the next progesterone cycle (the prescription says to take for 12 days from day 15 of cycle) and have had much higher anxiety than normal.
My older sister is also on HRT and said she was prescribed 100mg progesterone daily because she also gets migraines, so it seems that NHS prescribing guidelines are not quite so rigid as the GP seemed to think.
I googled about the difference in Canadian vs NHS prescribing and google AI tells me that the 100mg daily is common in Canada and explained the NHS preference for cyclical progesterone until definitely in menopause. AI also tells me that the reason for the migraines and high anxiety is due to the sharp drop off in progesterone in the cycling method and that the daily was providing me with a "steady state". I feel like this suited me much better than the cycling.
I have made a GP appointment to review the prescription - it's with a different GP from the same practice so will hopefully be better/more informed, although who knows.
I really want to return to the daily progesterone. Does anyone have any experience of daily being prescribed due to migraines and high anxiety?
I feel like the fact I was already on it for over a year should have been relevant, as well as the migraine factor, but I'm anxious about GPs here being rigid about prescribing.
