How do you treat an active FMF attack?

When you feel the familiar pain and fever of a Familial Mediterranean Fever (FMF) attack starting, your first instinct might be to take extra colchicine to stop it. Do not take extra colchicine during an active flare. Taking an additional or “on-demand” dose of colchicine will not stop or shorten an attack that has already started ^[1][2]. Colchicine is a preventative medication, not a rescue treatment ^[3][4]. Taking more than your prescribed daily dose can lead to dangerous toxicity. Instead, you should continue your regular daily dose and manage the acute symptoms using supportive therapies like rest, hydration, and pain relievers ^[1][5].

Why Extra Colchicine Doesn’t Work for Flares

Colchicine is the cornerstone of FMF management, but its job is to prevent attacks from happening and to protect you from long-term complications like AA amyloidosis (a buildup of abnormal proteins in your organs) ^[3][6].

• It is not a rescue drug: Medical guidelines emphasize that colchicine should not be used as an “on-demand” therapy for acute flares ^[1][2].
• Risk of toxicity: Increasing your dose without medical supervision does not relieve symptoms and puts you at a high risk for colchicine toxicity, which can cause dangerous and severe side effects ^[2].
• Maintain your routine: The best thing you can do with your colchicine during an attack is simply to keep taking your prescribed daily maintenance dose ^[1][7]. Strict, long-term adherence to this daily dose is the most effective way to prevent future attacks ^[7][8].

Managing Symptoms During an Active Attack

Because you cannot stop an attack once it begins, the goal of treatment during a flare is to keep you as comfortable as possible for the 1 to 3 days it typically takes to pass. This is called supportive care ^[1][2].

• Rest: Your body is fighting systemic inflammation ^[8]. Rest as much as possible until the fever and pain subside.
• Hydration: Drink plenty of fluids, especially if you have a fever.
• Pain Management: Over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen are often recommended to help control the pain and inflammation associated with serositis (the painful inflammation of the lining of your abdomen, chest, or joints) ^[5][9]. Always check with your doctor before starting NSAIDs, as they may not be safe if you have kidney issues. If over-the-counter pain relievers are not enough to manage your severe pain, contact your doctor for guidance rather than adjusting your medications on your own.
• Avoid Corticosteroids: It is worth noting that prescription steroid medications (like prednisone) are not part of the standard care for treating or preventing acute FMF attacks ^[10].

When to Contact Your Doctor

While most FMF flares pass with supportive care, you should contact your doctor if your attack lasts longer than 3 to 4 days, or if the pain is completely different from your typical flares. Because FMF abdominal pain can mimic surgical emergencies like appendicitis, you should seek immediate medical attention if your symptoms feel unusually severe or different than your usual pattern.

Watch for Colchicine Resistance

If you are experiencing frequent FMF attacks (such as one or more attacks per month) despite taking your daily colchicine exactly as prescribed, do not try to manage this by taking extra pills. You may be experiencing colchicine resistance, which means your body is still having inflammatory attacks even at the maximum tolerated dose of colchicine ^[1][11][12].

If this is happening, talk to your doctor. Medical guidelines recommend the use of IL-1 inhibitors (biologic medications like canakinumab or anakinra) for patients who are resistant to or cannot tolerate colchicine ^[11][13][14]. These medications target the specific inflammatory pathways involved in FMF to help control the disease and prevent flares ^[15][16].
