Colchicina, also known as colchicine, is a prescription anti-inflammatory medication derived from the plant Colchicum autumnale (autumn crocus). It has been used for centuries to treat joint swelling and pain.
Today, it is primarily used to treat:
- Gout attacks
- Familial Mediterranean Fever (FMF)
- Pericarditis (heart inflammation)
- Behçet’s disease
- Certain liver or skin inflammatory conditions under medical direction
Colchicina is not a general painkiller. It works best for inflammation caused by crystal buildup or immune system reactions.
How Colchicina Works
Colchicina reduces inflammation by targeting a process called microtubule polymerization, which slows the movement of inflammatory cells. This helps relieve swelling, redness, and pain during inflammatory attacks.
Its unique mechanism makes it especially effective in conditions like gout, where uric acid crystals trigger intense inflammation.
Medical Uses of Colchicina
Gout (Acute Attacks & Prevention)
Colchicina is commonly used during sudden gout flare-ups.
It helps reduce joint pain and swelling quickly when taken within 24 hours of symptoms.
Doctors also prescribe low daily doses to prevent future attacks.
Familial Mediterranean Fever (FMF)
People with FMF experience repeated episodes of fever and abdominal pain. Colchicina helps prevent attacks and reduce complications like amyloidosis.
Pericarditis
Colchicina is often combined with NSAIDs to treat inflammation of the heart lining. It reduces symptoms and prevents recurrence.
Behçet’s Disease
Used to control joint pain, skin lesions, and inflammation.
Off-Label Uses
Doctors may prescribe colchicina for:
- Primary biliary cholangitis
- Dermatologic inflammatory disorders
- Recurrent aphthous ulcers
(Always under medical supervision)
Recommended Dosage (General Guidelines)
Dosage varies depending on the condition and the patient’s health. Always follow a doctor’s prescription.
For Acute Gout Attack
- 1.2 mg first, followed by 0.6 mg after 1 hour
- Maximum dose is typically 1.8 mg in 1 day
For Gout Prevention
- 0.6 mg once or twice daily
For FMF
- 1–2 mg daily, depending on age and weight
