Colchicine in renal or hepatic impairment ( 4.4 )

Colchicine Concomitant administration of clarithromycin tablets and colchicine is contraindicated in patients with renal or hepatic impairment.

These include colchicine toxicity with colchicine; markedly increased transaminases with lomitapide; rhabdomyolysis with simvastatin, lovastatin, and atorvastatin; hypoglycemia and cardiac arrhythmias (e.g., torsades de pointes) with disopyramide; and hypotension and acute kidney injury with calcium channel blockers metabolized by CYP3A4 (e.g., verapamil, amlodipine,…

Colchicine: Life-threatening and fatal drug interactions have been reported in patients treated with clarithromycin and colchicine.

Concomitant administration of clarithromycin tablets and colchicine is contraindicated in patients with renal or hepatic impairment [see Contraindications ( 4.4 ) and Drug Interactions ( 7 )] .

Inhibition of both CYP3A4 and P-gp by dual inhibitors such as clarithromycin has been reported to produce life-threatening or fatal colchicine toxicity due to significant increases in systemic colchicine levels.

Patients with renal or hepatic impairment should not be given colchicine capsules with drugs that inhibit both P-glycoprotein and CYP3A4 inhibitors [see Drug Interactions (7) ] .

• Drug interaction with dual P-gp and CYP3A4 inhibitors: Co-administration of colchicine with dual P-gp and CYP3A4 inhibitors has resulted in life-threatening interactions and death ( 5.3 , 7 ).

Therefore, concomitant use of colchicine capsules and inhibitors of CYP3A4 or P-glycoprotein should be avoided [see Drug Interactions (7) ] .

Fatal drug interactions have been reported when colchicine is administered with clarithromycin, a dual inhibitor of CYP3A4 and P-glycoprotein.
