Does anyone have any information on drug interactions between atenolol (a beta blocker) and verapamil (a calcium channel blocker)?I was taking 240-360 mg/day of verapamil for seasonal cluster headaches with great success for several years until I developed a heart problem and am now being treated with atenolol to reduce blood pressure.How much verapamil can you take along with 50 mg/day of verapamil without droping Blood pressure too much or affecting cardiac conduction?Thanks,Tampa
