Conventional Medical Treatments for Myositis

Treatment for myositis focuses on reducing muscle inflammation, preventing increased weakness, and building strength. Depending on the cause and type of myositis, conventional medical treatments may include oral medications, physical therapy, intravenous immunoglobulin G therapy, surgery, or the discontinuation of certain substances.

Oral medications

Corticosteroids, such as prednisone, help to reduce inflammation and are usually the first line of medication treatment for myositis. They are sometimes prescribed in conjunction with immunosuppressant drugs, such as methotrexate. If myositis is caused by a bacterial infection, antibiotics may be prescribed to treat the underlying infection. If the infection is viral, antibiotic treatment is not effective. Pain medications, such as NSAIDs, may also be prescribed if needed.

Intravenous immunoglobulin G (IVIG) therapy

In cases that do not respond well to corticosteroids or immunosuppressant drugs, intravenous immunoglobulin G (IVIG) therapy may be used. This can help stop detrimental antibodies from attacking the muscles.

Physical therapy (PT)

Physical activity can improve muscle strength and flexibility. It can also help reduce inflammation. For these reasons, physical therapy is often recommended for the treatment of myositis. PT can also help prevent future injury.

Other treatments

If myositis is caused by a medication or drug, the best treatment is to discontinue use of the offending substance. Inflammation and related symptoms typically resolve within a few weeks.

For cases of myositis ossificans, surgery may be performed to remove the bony lump from the muscle if it does not dissolve naturally.
