Note: Colchicine has a narrow therapeutic index; drug accumulation can be associated with severe, including fatal, consequences. Monitor for signs/symptoms of colchicine toxicity and factors contributing to accumulation, such as hepatic/renal impairment or drug interactions.

Behçet syndrome

Behçet syndrome (off-label use):

Note: For treatment and/or prevention of recurrence in patients with arthritis, cutaneous lesions, and/or mucocutaneous ulcers.

Oral: 1 to 2 mg/day (or 1.2 to 1.8 mg/day) in 2 to 3 divided doses (Ref).

Calcium pyrophosphate crystal arthritis

Calcium pyrophosphate (CPP) crystal arthritis ("pseudogout") (off-label use):

Note: Due to limited data, experts often approach treatment and prophylaxis of these patients the same as patients with gout (Ref):

Prophylaxis: Patients with ≥3 CPP crystal arthritis attacks annually: Limited data available: Oral: 0.6 mg twice daily (maximum: 1.2 mg/day) (Ref). In patients with GI intolerance, some experts give 0.6 mg once daily or 0.6 mg every other day; however, evidence for a decrease in incidence of acute CPP crystal arthritis flare with doses lower than 0.6 mg twice daily is lacking (Ref).

Treatment : Note: Treatment should be initiated within 24 hours of onset (Ref). Limited data available; dosing based on expert opinion:

Day 1: Oral: 1.2 mg at the first sign of flare, followed in 1 hour with a single dose of 0.6 mg or 0.6 mg 3 times daily on the first day of flare; maximum total dose: 1.8 mg on day 1 of flare (Ref)

Day 2 and thereafter: Oral: 0.6 mg twice daily until flare resolves (Ref)

Familial Mediterranean fever

Familial Mediterranean fever (FMF):

Note: For prevention of attacks, and prevention of development and progression of amyloidosis.

Initial: Oral: 1 to 1.5 mg/day (or 1.2 to 1.8 mg/day) in a single daily dose; if single daily doses are not tolerated, give in divided doses. May consider a lower initial dose of 0.5 mg (or 0.6 mg) with subsequent dose escalation to improve tolerance (Ref). Note: Consider a higher initial dose (eg, up to 2 mg/day) in patients with greater disease activity and renal amyloidosis (but preserved renal function); in patients with secondary (AA) amyloidosis, daily doses >1.5 mg have been associated with prevention of disease progression and a reduction in protein excretion (Ref).

Titration: Oral: Increase the dose in 0.5 mg (or 0.6 mg) increments as clinically indicated (Ref); upwards titration is recommended in patients with attacks more frequent than every 3 months and/or with persistently elevated inflammatory markers. In general, a 3-month period of steady colchicine dosing is advised before judging response, although a more rapid titration schedule may be considered based on frequency of attacks (Ref).

Maximum: Oral: 3 mg/day (Ref)

Gout, prophylaxis during initiation of urate-lowering therapy

Gout, prophylaxis during initiation of urate-lowering therapy:

Oral: 0.6 mg once or twice daily (maximum: 1.2 mg/day). In patients with GI intolerance, some experts give 0.6 mg every other day (Ref).

Duration of prophylaxis:

Patients without tophi: 3 to 6 months after achieving target serum uric acid levels with urate-lowering therapy (Ref) or for the first 3 to 6 months of urate-lowering therapy (Ref).

Patients with ≥1 tophi: Optimal duration is unclear; some experts continue colchicine therapy for 6 to 12 months after achieving target serum uric acid levels with urate-lowering therapy and resolution of tophi, unless it is clear that tophi will not resolve despite persistent normal urate levels (Ref).

Gout, treatment

Gout, treatment (acute flares):

Day 1: Oral: 1.2 mg at the first sign of flare, followed by 0.6 mg after 1 hour (Ref); maximum total dose: 1.8 mg/day on day 1 (Ref). Initiate as soon as possible, ideally within 12 to 24 hours of flare onset (Ref); consider alternative agents if >36 hours since flare onset (Ref). Note: In patients who were already receiving prophylactic colchicine at the time of their flare, some experts give the higher 1.8 mg/day dosing regimen on day 1 of the flare, in place of the usual prophylactic dose (Ref).

Day 2 and thereafter: Oral: 0.6 mg once or twice daily until flare resolves (Ref). Some experts continue for 2 to 3 days after flare resolves (Ref). Note: In patients who were already receiving prophylaxis at the time of their flare, some experts give 0.6 mg twice daily (total dose: 1.2 mg/day) from day 2 until ~48 hours after flare resolution, and then resume the previous prophylactic dose (Ref).

Note: Historically, higher dose regimens have been given for gout flares; however, high-dose regimens have not been proven more effective than low-dose regimens and low-dose regimens have a better safety profile (Ref).

Pericarditis, acute or recurrent

Pericarditis, acute or recurrent (off-label use):

Loading dose: Loading doses are not necessary; avoiding loading doses may improve patient compliance and reduce adverse effects (Ref). If a decision to use a loading dose is made, the following is recommended:

Patients ≥70 kg: Oral: 1 mg (or 1.2 mg) every 12 hours on day 1, followed by maintenance dosing (Ref).

Patients <70 kg or unable to tolerate higher dosing regimen: Oral: 0.5 mg (or 0.6 mg) every 12 hours on day 1, followed by maintenance dosing (Ref).

Maintenance dosing:

Patients ≥70 kg: Oral: 0.5 mg (or 0.6 mg) twice daily (Ref)

Patients <70 kg or unable to tolerate higher dosing regimen: Oral: 0.5 mg (or 0.6 mg) once daily (Ref)

Duration of therapy:

Initial treatment (first occurrence): 3 months (Ref)

Recurrence treatment (first recurrence or multiple recurrences): 6 months (Ref)

Concomitant therapy: Use in combination with aspirin or a nonsteroidal anti-inflammatory drug (NSAID); may also add a corticosteroid for refractory cases. Alternatively, colchicine may be used with a corticosteroid alone if aspirin or an NSAID is contraindicated (Ref).

Postpericardiotomy syndrome, prevention

Postpericardiotomy syndrome, prevention (off-label use):

Note: Initiate preventive therapy preoperatively (48 to 72 hours prior to surgery (Ref)) or postoperatively (24 to 72 hours after surgery (Ref)).

Patients ≥70 kg: Oral: 0.5 mg (or 0.6 mg) twice daily for 1 month

Patients <70 kg: Oral: 0.5 mg (or 0.6 mg) once daily for 1 month

Stable ischemic heart disease, prevention of atherosclerotic cardiovascular events

Stable ischemic heart disease, prevention of atherosclerotic cardiovascular events (adjunctive therapy) (off-label use in the United States; labeled use for ER tablet [Canadian product]):

Note: Consider for use in stable patients already receiving other secondary preventative drug therapies.

Oral: 0.5 mg (or 0.6 mg) once daily (Ref).

Sweet syndrome

Sweet syndrome (acute febrile neutrophilic dermatosis) (alternative agent ) (off-label use):

Oral: Dosage range studied: 1 to 1.5 mg/day (1.2 to 1.8 mg/day) in 1 to 3 divided doses; the mean duration of therapy in one case series was reported as 15 days (range: 10 to 21 days) (Ref).

Vasculitis, idiopathic cutaneous small-vessel

Vasculitis, idiopathic cutaneous small-vessel (alternative agent) (off-label use):

Note: Consider for use in patients who do not respond adequately to initial therapy with corticosteroids (Ref).

Oral: Usual dose studied: 0.6 mg twice daily (Callen 1985; Callen 1987); if no response after 1 to 2 weeks, may consider increasing to 0.6 mg 3 times daily (Ref); continue therapy for 2 to 3 months after lesions heal and no new lesions develop, then taper and discontinue therapy over several weeks (Ref).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Adverse Reactions (Significant): Considerations
Gastrointestinal effects

Gastrointestinal effects, including nausea, vomiting, and diarrhea, are the most common side effects associated with colchicine therapy (Ref). Symptoms generally resolve quickly after dose reduction or treatment discontinuation (Ref).

Mechanism: Dose-related; related to the pharmacologic action. May be due to binding to tubulin (Ref) or an increase in prostaglandins, intestinal secretion, and gastrointestinal motility (Ref).

Onset: Rapid; generally occurs within 24 hours of treatment initiation, dose adjustments, or drug interaction (Ref).

Risk factors:

• Higher doses (Ref)

• Kidney impairment (Ref)

• Hepatic impairment (Ref)

• Concomitant use of P-gp inhibitors or CYP3A4 inhibitors (Ref)

Gloperba, Mitigare: Concomitant use of drugs that inhibit both P-gp and CYP3A4 in presence of renal or hepatic impairment; patients with both renal and hepatic impairment.

Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to colchicine; serious GI, hepatic, renal, and cardiac disease; existing blood dyscrasias.

Warnings/Precautions

Disease-related concerns:

• Hepatic impairment: Clearance is decreased in hepatic impairment; monitor closely for adverse effects/toxicity. Dosage adjustments may be considered depending on degree of impairment or indication, and may be affected by the use of concurrent medication (CYP3A4 or P-gp inhibitors). Concurrent use of P-gp or strong CYP3A4 inhibitors is contraindicated in hepatic impairment. Fatal toxicity has been reported.

• Renal impairment: Clearance is decreased in renal impairment; monitor closely for adverse effects/toxicity. Dosage adjustments may be required depending on degree of impairment or indication, and may be affected by the use of concurrent medication (CYP3A4 or P-gp inhibitors). Concurrent use of P-gp or strong CYP3A4 inhibitors is contraindicated in renal impairment. Fatal toxicity has been reported.

Special populations:

• Older adult: Use with caution in elderly patients; consider dosage adjustments.

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates; the "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP 1997; CDC 1982); some data suggest that benzoate displaces bilirubin from protein-binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer’s labeling.

• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated with hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Zar 2007). See manufacturer’s labeling.

Other warnings/precautions:

• Appropriate use: Colchicine is not an analgesic and should not be used to treat pain from other causes.

• Fatal overdose: Accidental and intentional fatal overdoses have been reported. Dosage associated with fatal toxicity is variable (eg, wide dosage range).

Food Interactions

Grapefruit juice may increase colchicine serum concentrations. Management: Administer orally with water and maintain adequate fluid intake. Avoid grapefruit juice.

Reproductive Considerations

Colchicine should not be discontinued in females with familial Mediterranean fever who are planning a pregnancy (EULAR [Ozen 2016]). Conception in females with rheumatic and musculoskeletal diseases should be planned during a period of quiescent/low disease activity (ACR [Sammaritano 2020]).

Continuation of colchicine therapy is strongly recommended for use in males with rheumatic and musculoskeletal diseases who are planning to father a child (ACR [Sammaritano 2020]). Use in males may rarely be associated with reversible infertility. A temporary dose reduction or discontinuation may be needed if azoospermia or oligospermia is related to use; however, men generally do not need to discontinue colchicine prior to conception (EULAR [Ozen 2016]).

Pregnancy Considerations

Colchicine crosses the placenta.

Based on available information, an increased risk of major birth defects or pregnancy loss has not been observed following maternal use of colchicine for the treatment of rheumatic diseases, such as familial Mediterranean fever (FMF) (EULAR [Ozen 2016]; Indraratna 2018). However, untreated FMF is associated with adverse pregnancy outcomes including abortion, miscarriage, and exacerbations of FMF attacks (EULAR [Ozen 2016]).

Colchicine can be continued during pregnancy in females with rheumatic and musculoskeletal diseases (ACR [Sammaritano 2020]). Available guidelines recommend continuing colchicine during pregnancy for the treatment of conditions such as FMF when there are no acceptable alternatives and discontinuation of treatment may lead to uncontrolled disease and adverse pregnancy outcomes. Increased monitoring during pregnancy is recommended; amniocentesis is not warranted (ACR [Sammaritano 2020]; EULAR [Ozen 2016]).

Breastfeeding Considerations

Colchicine is present in breast milk.

In a study of 4 lactating women taking colchicine for familial Mediterranean fever, breast milk and maternal serum concentrations peaked at the same time. Breast milk concentrations decreased by half 6 hours after the dose (Ben-Chetrit 1996). According to the manufacturer, exclusively breastfed infants are expected to receive <10% of the weight-adjusted maternal dose; however, reported breast milk concentrations are highly variable (Ben-Chetrit 1996; Guillonneau 1995; Milunsky 1991). Adverse effects in breastfed infants have been not observed with use.

According to the manufacturer, the decision to continue or discontinue breastfeeding during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.

Colchicine is considered compatible with breastfeeding and use should be continued in women with familial Mediterranean fever. Avoiding breastfeeding 2 to 4 hours after the maternal dose may decrease exposure to the breastfed infant (ACR [Sammaritano 2020]; EULAR [Ozen 2016]; WHO 2002).

Dietary Considerations

May need to supplement with vitamin B12. Avoid grapefruit juice.

Goal in gout (with urate-lowering therapy): <6 mg/dL; <5 mg/dL in patients with severe gout (eg, tophi, frequent attacks, chronic arthropathy) (EULAR [Richette 2017]). Levels <3 mg/dL are not recommended long term (EULAR [Richette 2017]).

Mechanism of Action

Disrupts cytoskeletal functions by inhibiting β-tubulin polymerization into microtubules, preventing activation, degranulation, and migration of neutrophils associated with mediating some gout symptoms. In familial Mediterranean fever, may interfere with intracellular assembly of the inflammasome complex present in neutrophils and monocytes that mediate activation of interleukin-1β.

Pharmacokinetics

Onset of action: Oral: Pain relief: ~18 to 24 hours

Distribution: Concentrates in leukocytes, kidney, spleen, and liver; does not distribute in heart, skeletal muscle, and brain

Vd: 5 to 8 L/kg

Protein binding: ~39%

Metabolism: Hepatic via CYP3A4 and glucuronidation; 3 metabolites (2 primary, 1 minor)

Bioavailability: ~45%

Half-life elimination: 27 to 31 hours (multiple oral doses; young, healthy volunteers)

Time to peak, serum: Oral: 0.5 to 3 hours

Excretion: Urine (40% to 65% as unchanged drug); enterohepatic recirculation, biliary excretion, and p-glycoprotein efflux also possible

Pharmacokinetics: Additional Considerations

Altered kidney function: Patients with ESRD had 75% lower clearance and prolonged elimination half-life.

Hepatic function impairment: Clearance is significantly reduced and plasma half-life prolonged in patients with mild to moderate cirrhosis.

Older adult: Mean peak plasma levels and AUC were 2 times higher in elderly patients; however, this may be caused by decreased renal function.
