Question: I was diagnosed with a prolactinoma 8 years ago and after treatment with bromocriptine have had 2 children (youngest is nearly 4). Last November my GP sent me back to my endochronologist as I had not been taking bromocriptine or any other meds since prior to falling pregnant. My bone density and B12 came back as low so I was put on a contraceptive pill. This was altered to a lower dose pill after continuing side effects. I came off the pill after continued side effects and was put on Cabergoline (1 dose per week). Side effects worsened including low blood pressure, anxiety, heart palpitations and lightheadedness. I also had a holter monitor test which came back OK. I came off the Cabergoline for a few weeks and was then put on Bromocriptine (once daily) however I was still having lightheadedness and palpitations so was advised to stop treatment again. That was nearly 5 weeks ago and I am still having episodes of lightheadedness and heart palpitations (though not as severe) as well as a period (most recent was 1 week ago). I had bloods done 2 weeks ago and thyroid, kidney & liver all came back normal but iron was low (came back as 6 when normal was classed as 10-30 & saturation was 8% with normal being 15-45%) I have also had 3 ECG since November - all of which were OK. I am over having these symptoms all the time and just want to get better so I can properly look after my family. Is there anything you can suggest as to what I can do or what else might be causing this trouble?

Thanks for the response. How long do iron supplements take to stabilise iron levels and how long do the effects of cabergoline/bromocriptine on the prolactinoma last for?
