Mav196, sorry to hear about your frightening experience last night. Unfortunately, from everything I have read on here and from my own experiences, you either get on with Utrogestan or you don't. If you suffer with migraines, Utrogestan in high doses can be a problem and I find that I can take 3 x 100mg capsules vaginally I get off relatively unscathed but any more than that is a tipping point and seems to act like a poison - sorry if that sounds dramatic. Utrogestan (and synthetic progesterone) changes the way your brain receptors work hence the low mood and migraines and even after it (technically) leaves your system, the changes it makes to your body take a while to adjust back to normal - in my case, it can be up to a few weeks.
Is there any way you can take a lower dose? You might want to read Professor Studd's website and you will see that he usually prescribes 100mg Utrogestan (preferably vaginally) for 7 days each month and you might find you can tolerate that dose. I know your menopause specialist prescribed your current regime but you could ask if you reduce the Utrogestan dose and have regular scans to make sure you are getting adequate clearance from the lower dose? The vast majority of women on the low dose never have a problem but it is worth being on the safe side.
