There is currently no cure for mixed connective tissue disease (MCTD). However, treatments can help manage symptoms of the condition. For example, medications such as over-the-counter or prescription nonsteroidal anti-inflammatory drugs may help with inflammation and pain of the muscles or joints. Glucocorticoids may be recommended in certain situations, such as during disease flares or when complications arise (e.g., aseptic meningitis, myositis, pleurisy, pericarditis, and myocarditis). Some people with MCTD require long term use of immunosuppressant medications.
Additional medications may be prescribed based on the signs and symptoms present in each person. For example, if a person with MCTD has developed symptoms similar to those of lupus, medications typically prescribed for people with lupus may be recommended.
