Prednisone and rosacea

Steroids can aggravate acne and rosacea. Blood pressure fluctuations
can cause flushes so check at intervals so keep an eye on that.
Hope you have access to a dermatologist if it needs treatment.

@mehow, I know you’re not using a topical steroid but here is a steroid related article from the National Rosacea Society website on your question.

"The good news is that effective treatment of rosacea-like symptoms due to topical corticosteroids is usually very simple: stop using the medication. It is important to work with your doctor to determine the best approach for your individual case."

Have you discussed the Rosacea symptoms with your doctor?

Many things can flare up after you reach the 5 mg threshold of Prednisone. It happens when the adrenal glands are slow to resume function again. As your prednisone dose drops below 5 mg, roughly the equivalent of the body's daily natural cortisol production, the body faces a shortage of steroids to control existing inflammation. It is sometimes called "rebound inflammation" or the "5 mg taper barrier."

The body faces a shortage of steroids to regulate existing inflammation which often leads to a flare of the original condition (PMR). You can also have flares of any preexisting inflammatory conditions which in your case is Rosacea.

Hopefully PMR won't flare up too!

@johnbishop I see a dermatologist and I do have a topical medication that is somewhat helpful. The amount of flares I'm having a prednisone just occurred to me. I'll discuss at the next visit. Thank you for your reply!

@dadcue I had no idea this was a thing! Thank you, hopefully as my body adjusts to the lower dose my rosacea "regulates". One more lovely PMR thing to deal with!

@seniormed Thank you, so far no blood pressure issues.
