Prednisone must be tapered gradually under your doctor. Stopping abruptly can cause a dangerous drop in your own cortisol (adrenal crisis).
Prednisone is a synthetic corticosteroid, very similar to cortisol, a hormone your adrenal glands make naturally. It is a powerful anti-inflammatory that rapidly calms an overactive immune system, controlling the inflammation that causes pain, swelling, and tissue damage in myositis and other autoimmune diseases. It usually works within hours to days, which is why it is often the first medication started while slower medications build up.
Reduces pain, swelling, and stiffness faster than almost any other medication, often within hours to days.
Controls severe inflammation in myositis, lupus flares, vasculitis, and polymyalgia when fast control matters.
Provides relief while slower DMARDs such as methotrexate or mycophenolate build to full effect.
In severe flares, it can prevent lasting damage to muscles, lungs, kidneys, and other organs.
Available in many strengths, so the dose can be tuned from low maintenance to high for an acute flare.
One of the few options that can be used safely in pregnancy and breastfeeding when needed.
Your doctor prescribed this because the expected benefits outweigh the risks for your situation. Here is the honest, full picture.
Your adrenal glands slow their own cortisol production while you take prednisone. Stopping abruptly can cause adrenal crisis: fatigue, weakness, low blood pressure, and potentially collapse. It must be tapered gradually under medical supervision.
Prednisone can be used in pregnancy and breastfeeding when needed. Always tell your doctor if you are pregnant, planning pregnancy, or breastfeeding, so the dose can be adjusted and monitored more closely.
This guide is for education, not medical advice. Myositis treatment is individual, and many of these medications are used based on specialist experience and research rather than a single approval for myositis. Never start, stop, or change a medication without your own doctor. Your doses and choices are decided with your care team at the Centre.
