For the treatment of sacroiliac arthritis, the cause needs to be clarified first. If the sacroiliac arthritis is caused by ankylosing spondylitis, oral non-steroidal anti-inflammatory drugs such as diclofenac sodium extended-release tablets, loxoprofen sodium, and fenpropathrin capsules can be administered. Also, oral medications such as salazosulfapyrimethamine and methotrexate can be administered for treatment. If the treatment is not effective, tumor necrosis factor biologics can also be applied for treatment. If degenerative arthritis is the cause, you can use glucosamine capsules, non-steroidal anti-inflammatory drugs, as well as topical Chinese medicines to activate blood stasis, reduce swelling and pain. If it is caused by multiple pregnancies, you can take oral NSAIDs for symptomatic treatment. The specific treatment method requires the patient to go to the hospital in time to improve the relevant examination to clarify the cause of the disease and give the corresponding disposal.
