About Colchicine
Colchicine is an established therapy for several painful and inflammatory disorders. In Singapore it is most commonly prescribed for acute gout attacks and for the prevention of gout flares, but the drug also plays a central role in managing familial Mediterranean fever and certain forms of pericarditis. The active ingredient-colchicine-belongs to the alkaloid class and exerts its effect by targeting cellular structures that drive inflammation. While the medication is available as a low-dose .5 mg tablet, its utility extends beyond the classic uses, and physicians may consider it for a range of conditions when evidence supports benefit. Understanding how colchicine works, when it is appropriate, and how to use it safely can empower patients to achieve better symptom control while minimizing risks.
What is Colchicine?
Colchicine is a plant-derived alkaloid extracted from the autumn crocus (Colchicum autumnale). It is classified as an anti-inflammatory agent that interferes with microtubule formation, a mechanism distinct from non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. The drug has been in clinical use for more than a century, originally for gout and later for the hereditary autoinflammatory disorder familial Mediterranean fever (FMF). In Singapore, colchicine is marketed under its generic name; several manufacturers produce the .5 mg oral tablet that is dispensed by pharmacies on prescription. Although the molecule is inexpensive, its narrow therapeutic window necessitates careful dosing and monitoring, especially in patients with renal or hepatic impairment.
How Colchicine Works
Colchicine binds to β-tubulin, a protein subunit that assembles into microtubules-structures essential for cell division and intracellular transport. By preventing microtubule polymerisation, the drug disrupts the mobility of neutrophils, a type of white blood cell that mediates acute inflammation. Neutrophil chemotaxis, degranulation, and the release of inflammatory cytokines are all attenuated, leading to a rapid decline in the inflammatory cascade that drives gouty arthritis and FMF attacks.
Pharmacokinetically, colchicine is absorbed within 30 minutes after oral ingestion, reaching peak plasma concentrations in about two hours. Bioavailability is approximately 45 % due to extensive first-pass metabolism, primarily via the cytochrome P450 3A4 pathway and P-glycoprotein efflux transporters. The drug’s elimination half-life ranges from 9 to 12 hours, but because it accumulates in leukocytes and renal tissue, steady-state concentrations may persist for several days. This prolonged cellular retention underpins both its therapeutic efficacy and the potential for toxicity if dosing intervals are not respected. Metabolites are excreted renally (≈30 %) and hepatically (≈70 %), making dose adjustments advisable in patients with reduced kidney or liver function.
Why Colchicine is Used for Pain and Inflammation Conditions
-
Acute gout flares Gout arises from monosodium urate crystal deposition in joints, which provokes an intense neutrophil-driven inflammatory response. By incapacitating neutrophil migration and degranulation, colchicine curtails the swelling, erythema, and throbbing pain that characterize an attack. Clinical trials have shown that a low-dose regimen (.5 mg once or twice daily) shortens the duration of pain by roughly 30 % compared with placebo, while also reducing the need for rescue NSAIDs.
-
Familial Mediterranean fever (FMF) FMF is an autosomal-dominant autoinflammatory disease marked by recurrent serositis, fever, and abdominal pain. The pathogenic hallmark is uncontrolled activation of the NLRP3 inflammasome, leading to excess interleukin-1β production. Colchicine’s microtubule inhibition stabilises the inflammasome complex, thereby preventing cytokine release. Long-term daily therapy (often .5 mg to 1 mg) markedly lowers the frequency of attacks and reduces the risk of secondary amyloidosis.
-
Pericarditis (especially recurrent cases) Inflammatory pericardial disease can be refractory to NSAIDs and colchicine adds value by limiting neutrophil infiltration into the pericardial sac. Studies comparing colchicine plus standard therapy versus standard therapy alone report a 50 % relative reduction in recurrence rates, supporting its inclusion in guideline-based management of idiopathic or viral pericarditis.
Off-Label and Investigational Uses of Colchicine
Beyond its licensed indications, colchicine has been explored in several off-label contexts. Small-scale trials suggest potential benefit in Behçet’s disease, where neutrophil hyperactivity contributes to mucocutaneous ulceration; colchicine may reduce ulcer frequency when added to standard immunosuppressive regimens. In the cardiovascular arena, low-dose colchicine (.5 mg daily) has been investigated for secondary prevention after myocardial infarction, aiming to suppress the chronic inflammation that fuels atherosclerotic plaque instability. The COLCOT and LoDoCo2 trials reported modest reductions in major adverse cardiovascular events, though the evidence remains insufficient for routine adoption. Off-label use only under qualified healthcare provider supervision.
Is Colchicine Right for You?
Ideal candidates for colchicine are adults who experience episodic inflammatory attacks that respond poorly to NSAIDs or who require prophylaxis to prevent recurrent flares. Patients with well-controlled kidney function (eGFR > 30 mL/min) and normal hepatic enzymes usually tolerate the standard .5 mg tablet without dose alteration. As noted above, individuals with severe renal impairment, significant hepatic disease, or concurrent strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole) should avoid colchicine or use it only after dose reduction, because drug accumulation can precipitate toxicity. Older adults may be more sensitive to gastrointestinal upset and should start at the lowest effective dose. Pregnant or lactating women are generally advised against colchicine unless the therapeutic benefit clearly outweighs potential fetal risk. Discussing personal medical history with a clinician will help determine whether colchicine offers a net advantage over alternative agents such as NSAIDs, corticosteroids, or newer urate-lowering therapies.
Taking Colchicine Effectively
Colchicine tablets are best taken with a full glass of water; food does not markedly affect absorption, but some patients find that a light snack reduces the likelihood of stomach discomfort. Consistency is key: for prophylactic use (e.g., FMF, recurrent pericarditis) the pill should be taken at the same time each day to maintain stable plasma levels. If a dose is missed, take it as soon as remembered provided it is not within six hours of the next scheduled dose; otherwise, skip the missed dose and resume the regular schedule-doubling up can increase toxicity risk. Because colchicine’s therapeutic window is narrow, avoid self-adjusting the dose based on symptom severity. Setting phone reminders or using a medication-tracking app can improve adherence, especially when the regimen is part of a broader polypharmacy plan. When traveling, keep tablets in original packaging with a copy of the prescription to satisfy customs regulations.
Understanding Side Effects and How to Manage Them
The most common adverse effect of colchicine is gastrointestinal irritation, manifesting as nausea, abdominal cramping, or diarrhoea. These symptoms arise from the drug’s impact on rapidly dividing cells of the intestinal mucosa, a direct consequence of microtubule disruption. To mitigate discomfort, patients should start with the lowest effective dose and ingest the tablet with food or a milky beverage. Hydration helps alleviate diarrhoea; if stools become watery or persist beyond 48 hours, contacting a healthcare professional is advisable.
Rare but serious toxicities-such as myopathy, severe neutropenia, or hepatic dysfunction-typically occur only with overdose or when colchicine interacts with CYP3A4 inhibitors. Warning signs include unexplained muscle weakness, dark urine, persistent fever, or jaundice. Prompt medical evaluation is essential for these symptoms, as early intervention can prevent irreversible damage. Overall, most users tolerate low-dose colchicine well when dosing guidelines are respected.

Frequently Asked Questions
-
How quickly does colchicine start working during a gout flare? After the first .5 mg dose, pain relief often begins within 12-24 hours as neutrophil activity wanes, though full resolution may take several days depending on crystal burden.
-
Can I take colchicine together with allopurinol? Yes, colchicine is frequently prescribed as a short-term bridge when initiating allopurinol, helping control flares while serum urate levels gradually decline. Dose timing should be spaced to avoid simultaneous peak plasma concentrations.
-
What should I do if I experience mild diarrhoea? Increase fluid intake, eat a bland diet, and consider taking the next dose with food. If diarrhoea persists beyond two days or is accompanied by dehydration, seek medical advice.
-
Is colchicine safe for people over 70 years old? Older adults may have reduced renal clearance, making them more susceptible to toxicity. Starting at .5 mg every other day, with careful monitoring of kidney function, is a common strategy.
-
How does colchicine differ from NSAIDs in treating inflammation? NSAIDs inhibit cyclo-oxygenase enzymes, reducing prostaglandin synthesis, whereas colchicine prevents neutrophil migration by targeting microtubules. This distinct pathway allows colchicine to be effective when NSAIDs are contraindicated or ineffective.
-
Can I use colchicine to prevent future gout attacks? Low-dose daily colchicine (.5 mg) is approved for flare prophylaxis, especially during the first months of urate-lowering therapy when the risk of attacks is highest.
-
Will taking colchicine affect my blood test results? Colchicine can cause mild, reversible reductions in white-cell counts; routine blood work may show a slight dip in neutrophils, which usually resolves after dose adjustment or discontinuation.
-
Is there any dietary restriction while on colchicine? No specific foods must be avoided, but excessive alcohol can elevate uric acid levels and provoke gout, indirectly undermining colchicine’s benefit. Moderation is advisable.
-
How does colchicine interact with antibiotics like clarithromycin? Clarithromycin strongly inhibits CYP3A4, raising colchicine plasma concentrations and heightening toxicity risk. Co-administration generally requires colchicine dose reduction to .25 mg or avoidance altogether.
-
What monitoring is required during long-term colchicine therapy? Periodic assessment of renal and hepatic function, as well as complete blood counts, helps detect early signs of toxicity. Most clinicians schedule labs every three to six months for stable patients.
-
Can colchicine be used during pregnancy? Current evidence suggests limited safety data; the drug is classified as Category D in some regions, indicating potential fetal risk. It should be prescribed only if the expected benefit justifies exposure, after thorough counseling.
