Methylprednisolone
2 medicines
Methylprednisolone is a corticosteroid used to calm inflammation from allergic reactions, asthma flares and autoimmune diseases such as rheumatoid arthritis and lupus. After more than a few weeks of use it must be tapered off slowly rather than stopped, because your adrenal glands scale back their own hormone production during treatment.

Key facts
- Methylprednisolone (brand Medrol) is a corticosteroid, a synthetic version of the hormone cortisol that dampens inflammation and immune activity.
- It treats flare-ups of asthma, severe allergic reactions and autoimmune diseases, usually as a short tapering course of tablets or an injection.
- Never stop methylprednisolone suddenly after taking it for more than 2 to 3 weeks. Your adrenal glands slow their own cortisol output during treatment, and stopping abruptly can trigger adrenal crisis, a medical emergency. Doses must be tapered down under medical guidance.
- Seek urgent care for black or bloody stools, severe stomach pain, or signs of infection such as fever, since steroids can mask the usual warning signs.
What methylprednisolone treats
Methylprednisolone treats short, severe flare-ups of asthma and allergic reactions, and it eases the joint pain and swelling of rheumatoid arthritis, lupus and other autoimmune diseases. Doctors also use high-dose pulses for multiple sclerosis relapses and severe inflammatory eye conditions, and it can be injected directly into a joint to calm a local arthritis flare. It is not a treatment for infection itself, though it is sometimes given alongside antibiotics to control inflammation.
How methylprednisolone works
Methylprednisolone mimics cortisol, the hormone your adrenal glands make to regulate inflammation. It enters cells and switches off the genes that produce inflammatory chemicals while switching on genes that make anti-inflammatory proteins. This calms swelling, redness and immune activity throughout the body. Because it copies your own hormone, prolonged use signals the adrenal glands to cut back their natural output.
Before you take it
- Tell your prescriber about diabetes, high blood pressure, stomach ulcers, osteoporosis, glaucoma, or any current infection, especially chickenpox, shingles or tuberculosis, since steroids can worsen these conditions or hide their symptoms.
- Avoid live vaccines while taking methylprednisolone, since it suppresses the immune response the vaccine needs to work safely.
- If you are pregnant or breastfeeding, use it only under medical supervision; short courses are generally considered lower risk, but long-term or high-dose use needs specialist input.
- NSAIDs raise the risk of stomach bleeding when combined with methylprednisolone.
Side effects
Common effects include increased appetite, trouble sleeping, mood changes, fluid retention and a raised blood sugar level.
Stop and seek urgent medical care for:
- Signs of adrenal crisis: severe weakness, dizziness, vomiting or fainting, especially after missing a dose or stopping suddenly.
- Black or bloody stools, or severe stomach pain.
- Vision changes or eye pain.
- Signs of infection, including fever, that appear or worsen during treatment.
Safety essentials
- Never stop methylprednisolone abruptly after more than 2 to 3 weeks of use. Your prescriber will taper the dose gradually so your adrenal glands can recover their own cortisol production; stopping suddenly can trigger adrenal crisis.
- Long-term use raises the risk of osteoporosis, cataracts, high blood sugar and muscle weakness; your doctor may check your bone density, blood sugar and eyes during extended treatment.
- Carry a steroid treatment card or medical alert if you are on a prolonged course, so emergency staff know you may need extra steroid cover during illness, injury or surgery.
