My blood pressure used to drop a bit at the beginning of each reduction, but was still in the low normal range. Before PMR I occasionally had low heart rate (42 bpm) and/or low blood pressure and a nurse told me it can sometimes happen with dehydration. So whenever it happened I drank two full glasses of water to get things back to normal within an hour or so. Now I drink extra water every day with no further problems. I don't know if that's your problem, but drinking more water could be worth trying.

Low blood pressure is also one of the symptoms of adrenal insufficiency, so as I drop to 2.5mg pred I'm keeping a close eye on it, but at 6mg, I don't think adrenal insufficiency is likely to be your problem. What does your doctor say?

Does anyone’s blood pressure go low while tapering down ?i have pmr been on prednisone for 2 yrs i can’t get past 7 mg each time I go to 6 mg my pressure drops and I feel terrible ..
---------------------
I hate to complain too much about prednisone. It did spare me from having too much pain.

I had a problem with feeling terrible when I reached 7 mg. My belief was that it was a combination of both a low cortisol level and symptoms of PMR returning.

I didn't have the problem when Actemra controlled my PMR symptoms but I felt terrible when I reached 3 mg. That was a low enough dose of Prednisone for my cortisol level to be checked. My cortisol level was low so I needed to stay on 3 mg for 6 months.

Low blood pressure was never a problem until I was able to get off Prednisone. When I was taking Prednisone, my blood pressure would sometimes be higher than 200/100 but not all the time. Three blood pressure medications were needed to control my "labile" blood pressure.

After Prednisone was stopped my blood pressure didn't drop all of a sudden but it gradually decreased over time. One by one my blood pressure medications were stopped. Now my blood pressure is normal without any blood pressure medications.

I have learned to appreciate everything that cortisol regulates in the body. It regulates inflammation, metabolism and so much more. When I was taking Prednisone ... it was impossible for me to keep everything regulated.
