Anyone switched to hydrocortisone from prednisone for tapering?

Pulled this info off Claude AI:
Yes, switching to hydrocortisone (HC) toward the end of a prednisone taper is actually a recognized clinical strategy. Here’s what the evidence and patient experiences show:

Why some doctors make the switch

Once you’re near a physiological dose (around 5 mg/day prednisone equivalent), a common approach is to switch to an equivalent dose of hydrocortisone — about 15–20 mg/day in 2–3 divided doses — and then reduce by 2.5 mg every 1–2 weeks.  The idea is that HC more closely mimics your body’s natural cortisol and has a shorter half-life, which can help the adrenal axis “wake back up.”

The conversion math

Prednisone is about 5 times stronger than hydrocortisone, so 5 mg of prednisone is roughly equivalent to 20 mg of hydrocortisone. Because HC clears faster, that dose often needs to be split across the day. 

What people experience

Reactions are mixed. Some people feel more fatigued on HC compared to pred, while others find it gentler. One person reported significant swelling after switching to HC and ended up going back to prednisone, with the swelling resolving within days. 

A note of caution

Interestingly, some UK guidelines actually recommend that adults weaning prednisolone not be routinely switched to hydrocortisone  — so there’s genuine debate among specialists, and practice varies quite a bit.

I've also read up on it and used Claude for my own personal tapering. From what I gather, hydrocortisone is beneficial when a fast taper is necessary or when tapering hits a road block. In my case I'm doing a fast taper due to an SMM diagnosis. It is also my understanding that whereas we in the US are prescribed prednisone, those in the UK are prescribed prednisolone. There's a difference but I'm not sure what that is because I'm on prednisone.

@kjoed53 ame drug basically just a different metabolic pathway. The prednisone is converted by the liver before it is used but prednisolone doesn't require that extra step. Prednisolone is easier on the liver and commonly prescribe in Australia as well. I always joke that it's probably because of the level of alcohol consumed.

@gmdb

Prednisolone is easier on the liver.

I guess you are right about the amount of alcohol consumed in Australia, the UK and the rest of Europe compared with the USA. We aren't too far behind though.

@gmdb
Is tapering easier on prednisolone or the same?

@kjoed53 I understand it’s the same. Sometimes when stocks are low of prednisolone, they substitute prednisone. I made no difference to tapering. Sometimes when tapering has gone wrong due to too much pressure from the doctors forcing the taper, I’ve had to go to Emergency with pain from a sudden in inflammation. They’ve given me hydrocortisone intravenously. It’s worked quickly and I’d agree that it seemed a more gentle drug. Although I have been told it’s not good for managing pain levels longer term.

@dadcue Hmm, not as bad as I thought we were, and we may have improved more in the last few years. The younger generations don’t seem to be drinking as much as their elders did in their youth.

From the previous comments, are we to conclude a link between PMR and alcohol consumption? 🙂

@ventmann Ha Ha - but seriously it's hard to say. Alcohol is inflammatory like many things - there are people who argue that tomatoes are one of the worst inflammatory foods and others that they are anti-inflammatory. In in my case I'd given up alcohol for several years for general health way before PMR hit. But don't know if anybody has tested for lifetime total consumption of alcohol as a risk factor.

@ventmann

I'm not sure if there is a link between PMR and alcohol consumption. For sure chronic alcohol "abuse" isn't good for anyone.
