I try to be an informed healthcare consumer and was recently prescribed prazosin for PTSD related nightmares (note the time of this post). It apparently does an amazing job at stopping them although they do return once you stop the medication (if you don't resolve the trauma itself).

My p-doc told me about a month ago that the dose was 1 mg a night but when I did a med search online and most of the articles said that the dose for nightmares due to PTSD were 10 to 13 mg. When I told her what I had read she didn't actually say anything for almost a month and I diligently took 1 mg each night until it ran out this past Friday. When I asked her about it again to get a refill she told me that I must have trust issues with other people because I questioned her about the medication dose.

She then said that it was different for women then for men? I have never heard of a medication having a different dose for men versus women (perhaps vary by weight but I doubt I would need 1/10 of what a man needs since its not like I only weigh 18 lbs or something) but I am hardly going to question that now.

I can't afford to switch providers and I want to maintain a good relationship with her so do I just assume she is right and take a dose that clearly isn't working for me or ask her for a source to her recommendation or something else? I did find the email for one of the researchers on some of the studies but I don't know if he would answer me or not.
