Advice on cortisol levels

Hello all!

I've just had a morning cortisol test on 4.5mg prednisolone (down from 5mg recently which I've been on for about six years now). The result is 132 nmol/l.

I know there are pred experts here - is this result a sound basis for further reduction? I'm going ahead anyway, very slowly, but feel pretty chuffed I've got down to 4.5mg so far. Not been able to do that before now.

Am I right in thinking it would be wise to get down to 4mg and then do a Synacthen test to be sure?

Ta! Hope everyone is warm and storm free now.

You won't get very reliable results at this stage on 4,5mg pred - but if you have a basal cortisol of 132 nmol/l while in 4,5mg pred that is pretty encouraging since 4.5mg is plenty to still be suppressing cortisol production.

If it were me, I'd take that as a baseline and continue tapering VERY slowly and get basal cortisols done every so often to see if it rises, even if it is only very slowly. If you can get to 3mg it is probably worth then asking for a synacthen test to see if there is any reserve capacity when the adrenal glands are kicked hard chemically. That still isn't a guarantee that the whole set-up is capable or responding reliably in day to day situation - but it can take up to a year after getting off pred altogether for that to happen.

One of the ladies on the PMRGCAuk forum got a pretty so-so result at 3mg but by 1,5mg it was looking much better and she went on to get off pred altogether.

Thank you so much - that's really helpful. That sounds like a plan. Yep I'm going very slow, especially as I have a new job (I reckon if I took a year off I could do it). It seems I have a way to go yet! x

Thank you - I joined before but left I think. I've tried various ways of doing it but what seems to work for me is .5mg drop one day in a week, then two days etc. I maintain if I'm feeling a bit iffy, then start again. This time I've not had the joint pains etc. I normally get. I don't know why!

Just drop in any time if you have a question. Does one have to join a group to post?

Thank you! I think this is the first time I've managed it. Not sure what's changed but I am on a histamine control regime which deals with many symptoms I have. Best of luck with your reduction. Keep well and rested, and keep trying xx

I had tacrolimus added to my meds to help with my pred reduction but I've been off it for several weeks in order to have a surgery on my ankle so I'm not dropping just now until ive been back on it a few weeks. I can assure you im well rested as im in plaster for 6 wks non weight bearing. Its quite some time since I was on 7.5mgs and i can't get below 7mgs so I'm approaching my tipping point 😱 x

I'm so pleased for you that you've got down to 4.5mg. Am I right in thinking that you've been taking 1x2.5mg + 2x1mg tablets?

Sorry, if that sounds like a daft question but my Rheumatology folk are insistent that I continue on 5mg forever, as a "maintenance dose", which is never open for discussion. I suspect that it's a case of (financial) convenience as monitoring below that dose requires cash!

Can I ask which part of the UK you are in? How do you access an Snyacthen test? On the NHS?

I'm sorry that I've inadvertently made this post 'all about me' but I'm so frustrated to have been kept on any steroids for the last 11 years with no hope of ever getting off them completely, that I'm desperate for any answers.

I wish you all the very best with your journey and thanks for any help you can give.

Yes I'm on 2.5mg and 2 x 1mg gastro resistant tablets. I'm afraid you just have to insist.

I'm in Gloucestershire, and connected to Bath rheumy. They are very insistent I come off steroids. They'd prefer me to be on methotrexate than steroids.

If you feel well enough, insist.

You could start by asking your GP if they would do a basal cortisol level - that is cortisol done on a blood sample taken between 8am and lunchtime - timing isn't that critical for this. It just needs a blood sample which the GP practice can do. If the result is under 100 nmol/L, you are definitely adrenally insufficient. If you are above 450nmol/L, you are almost certainly fine. In between is equivocal and then you would need a proper synacthen test to clarify.

I'm not sure if a GP can request a synacthen test - it must be done at a Day Clinic at the hospital and not at the practice but they may be able to order one. You would have to ask them.

Normal values for a blood sample taken at 8 in the morning are 5 to 25 mcg/dL or 140 to 690 nmol/L
