The following medications may interact with verapamil:

  • Cytochrome inducers/inhibitors – Clinically significant interactions have been reported with inhibitors of CYP3A4 (e.g., erythromycin, ritonavir) causing elevation of plasma levels of verapamil while inducers of CYP3A4 (e.g., rifampin) have caused a lowering of plasma levels of verapamil
  • HMG-CoA reductase inhibitors – The use of HMG-CoA reductase inhibitors that are CYP3A4 substrates in combination with verapamil has been associated with reports of myopathy/rhabdomyolysis.
  • Ivabradine – Concurrent use of verapamil increases exposure to ivabradine and may exacerbate bradycardia and conduction disturbances. Avoid co-administration of verapamil and ivabradine.
  • Aspirin – In a few reported cases, co-administration of verapamil with aspirin has led to increased bleeding times greater than observed with aspirin alone
