Hi PMB63
I assume that the 200 mg capsules you have been given are either old stock from the dispensary/pharmacy or maybe the ones used for fertility (in which case you have a very diligent doctor!). The 200 mg capsules are still made for fertility (or were last time I looked) but the leaflet is different because the instructions are not for menopause - it will be obvious which ones you have.
I use Utrogestan vaginally and have done so for 3 1/2 years. Although the French spc (leaflet instructions) recommend vaginal use (at the same dose) if there are side effects from oral use, research has shown that the amount needed for vaginal use is lower than for oral use, so you might be able to get away with using 100 mg only if you are on a 28 day cycle.
I would see how you feel on this dose and hopefully you will feel fine and sleep better! You might also find that even if you have initial side efefcts your body will get used to the progesterone after a few days.
By the way re fibromyalgia - I'm sure you've read about this and will know that fibromyalgia syndrome, like Chronic Fatigue Syndrome can result from hormone deficiencies - and especially thyroid, but also teststerone and oestrogen. I really hope that your symptoms reduce or disappear through taking this bio-identical HRT so that you don't have it any more

.
Don't worry about what you read on here because women only come here initially because of problems so there will be lots of women out there taking utrogestan orally and vaginally without a care in the world!
Do you also use vaginal oestrogen? I like to make sure this area is well plumped up with Vagifem or Gynest before I start my Utrogestan - but you may well be fine in that dept anyway!
Hope it goes well and do keep us posted as to how you are doing!
