Danazol, diltiazem, dronedarone, or verapamil with higher doses of lovastatin: The dose of lovastatin should not exceed 20 mg daily in patients receiving concomitant medication with danazol, diltiazem, dronedarone, or verapamil.

The benefits of the use of lovastatin in patients receiving danazol, diltiazem, dronedarone, or verapamil should be carefully weighed against the risks of these combinations.

If lovastatin is co-administered with verapamil, do not exceed doses greater than 40 mg daily of lovastatin ( 7.2 )

Limit the daily dose of lovastatin to 40 mg.

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.
