PMR Dosages and Managing Symptoms
I've read through the discussions and note all the different dosages of prednisone, different lengths of time taking prednisone, plus the addition of other meds, for PMR. I also note that the tapering of dosages and time frames are so varied from person to person. It appears there is not a set standard among physicians. How does one know if they were/are receiving the right dosage? Obviously, if symptoms subside, the dose is working, but after tapering if the symptoms return, was the initial dosage correct? I've also read that a person shouldn't be on prednisone long term, but there are many who've been on it for a few years. Its all very confusing.

I liked your story! I hope Kevzara will work for you.
I wanted to add something about inflammation markers or PMR markers as you say. When I started Actemra (tocilizumab) about 4 years ago my inflammation markers "bottomed out." Kevzara will probably cause your inflammation markers to drop too. Actemra and Kevzara both target the same inflammation pathway.
Due to the blockade of IL‐6 signalling, Actemra (tocilizumab) inhibits the hepatic production of C‐reactive protein (CRP) and other acute phase proteins like the erythrocyte sedimentation rate (ESR). This is true for Actemra (tocilizumab) and I assume it is true for Kevzara.
My inflammation markers were always elevated when I took prednisone. After Actemra was started my inflammation markers were close to zero. I was concerned because I had never seen my inflammation markers so low. I was so concerned that I asked my doctor if my inflammation markers were too low!
Actemra interrupts the production of C Reactive Protein (CRP) so it is no longer a reliable measure of disease activity. This was learned from patients with RA who were treated with Actemra.

Another thing to be aware of --- if you have an active infection your CRP and ESR will stay low too. Potentially a doctor could overlook the possibility of an infection when you are on Kevzara or Actemra.
I confess I have done very little research on the whole subject, so I appreciate your insights!
No problem. I don't know too much about Kevzara. I will be looking forward to your insights into Kevzara.
I only know about Actemra but it isn't FDA approved for PMR. Actemra is approved for the treatment of GCA. I don't have much insight into GCA because I was never diagnosed with GCA ... only PMR.
I'm just happy my rheumatologist had insight when he said, "since Actemra works for GCA ... it should work for PMR too." I'm off prednisone now after 12 years of treatment with prednisone for PMR. I'm very happy with Actemra! I was lucky to get Actemra for PMR.
Now Kevzara is available for PMR but it wasn't 4 years ago when my rheumatologist wanted me to try Actemra.
Please keep us updated as to the Kevzara.
Four weeks in I see no difference on Kevzara, although I have speeded up the prednisone taper to 1 mg every two weeks with no ill effects. Today I take my third 200 mg dose of Kevzara and reduce from 4 mg to 3 mg P. From what I read, reducing when at a low dose of P is where it gets tricky. Not surprising as the percentage decrease increases, i.e., 4 to 3 is a bigger drop than 10 to 9.
I will post again when I have news. Best wishes...to all of us.
Will 3 mg be the lowest dose you have been on since the start of PMR?
How long have you been taking prednisone? What was your average dose during this time?
These questions are important because of how prednisone suppresses adrenal function and cortisol production. I took prednisone for 12 years so my doctors expected that I would have problems tapering off prednisone.
My tapering problems would begin at 10 mg and pain would get much worse at 7 mg. I couldn't tolerate being on 7 mg very long. I didn't think Actemra was working either for the first 3 months until I reached 7 mg. I was doing Actemra injections every 2 weeks back then. I didn't have an increase in pain as I was tapering from 10 mg to 7 mg --- I only tapered by 1 mg per month.
I wasn't liking Actemra and I was receiving negative feedback from another PMR forum about using Actemra for PMR. I increased my taper to 1 mg per week thinking I wanted to get the inevitable PMR flare over with in order to increase my prednisone dose again.
When I tapered by 1 mg per week, I felt unwell by the time I got to 3 mg. I told my rheumatologist who was surprised that I was on 3 mg already. My rheumatologist told me to stop the taper. My cortisol level was low so that explained the overwhelming fatigue I felt.
Long story ... but I had to stay on 3 mg for 6 months before my cortisol level improved.
An endocrinologist told me when it might be safe to stop prednisone --- it wasn't my rheumatologst. The two doctors did talk to each other. The endocrininologist said from an adrenal standpoint it might be safe. My rheumatologist wasn't so sure from a PMR standpoint but said I should give it a try and go to zero.
The reason we taper slowly in the first place is because prednisone suppresses the cortisol production from the adrenals. When we taper our prednisone dose lower, the adrenals need some time to resume cortisol production.
How much time the adrenals need is mostly related to the duration of prednisone use and the cumulative dose of prednisone over the time period prednisone was taken.
Three mg is the lowest dose I have taken since starting prednisone almost exactly a year ago. Most of this time I have been decreasing at 1 mg per month, but speeded up the decrease when I started the Kevzara.
I do not have an endocrinologist involved, only a rheumatologist. We have not discussed cortisol or adrenals at all.
I track my pain and prednisone intake. As you can see, I show a baseline
pain of 1, but I think that that minor pain is just old man stuff. I have
been mostly PMR-symptom-free for most of that time.
Nicely said. Liked your comment about trying to distinguish "old man pain" from PMR or other actual conditions -- many will identify with that. I am happily tapering from 25 mgs of prednisone downward on a very slow year-long plan that (knock on wood) appears to be working well, with only very slight wrist and arm discomfort to date. Had wonderful success splitting doses morning and evening, something prompted by discussion on this site, which I am very grateful to have available. Best holiday wishes to all.
Just be aware of the symptoms of secondary adrenal insufficiency from long term prednisone use. Interestingly, symptoms of secondary adrenal insufficiency can mimic PMR symptoms.

Most people aren't aware of this. Many people are able to successfully taper off prednisone slowly without adrenal problems. It isn't just "old man stuff" that is hard to distinguish from PMR. When secondary adrenal insufficiency becomes a factor, it is hard to distinguish from PMR too.
For me, I still have some problems with old man stuff. When my doctors look at how long I took prednisone, they are convinced that some of my problems are related to how long I took prednisone for my autoimmune problems.
My rheumatologist says I have a "full range" of things but she was very happy I am finally off prednisone while PMR stays in remission. Unfortunately, my rheumatologist seems very reluctant to stop Actemra anytime soon. Fortunately, I don't seem to have any side effects from Actemra.
If and when Actemra stops working, my rheumatologist says I can try Kevzara. Unlike prednisone, it is relatively easy to stop Actemra as long as PMR stays in remission.
