Description
Colchicine is a medication primarily used to treat and prevent gout flares and familial Mediterranean fever (FMF). It works by reducing inflammation and is derived from the autumn crocus plant (Colchicum autumnale). Here are some key points about colchicine:
Uses:
1. Gout:
Treats acute gout attacks by reducing inflammation caused by uric acid crystals.
Prevents future gout flares when used as a long-term therapy.
2. Familial Mediterranean Fever (FMF):
Helps prevent inflammation and complications such as amyloidosis in people with FMF.
3. Pericarditis:
Sometimes used as part of the treatment for pericarditis to reduce inflammation and prevent recurrence.
Dosage:
Acute gout attack: 1.2 mg initially, followed by 0.6 mg after 1 hour (maximum 1.8 mg in 24 hours).
Prophylaxis: 0.6 mg once or twice daily, adjusted based on individual needs and tolerance.
Side Effects:
Common: Diarrhea, nausea, abdominal pain.
Severe: Bone marrow suppression, neuromuscular toxicity, kidney or liver dysfunction.
Precautions:
Avoid in severe kidney or liver impairment without dose adjustment.
Drug interactions (e.g., with certain antibiotics or antifungals) can increase the risk of toxicity.
Not recommended during pregnancy unless necessary.
Toxicity:
Colchicine has a narrow therapeutic window. Overdose can cause serious effects, including multi-organ failure, and can be fatal. Always use it as prescribed.
