I have been taking cozaar (losartan) (generic form) 50mg 2x day for several years and the doctor also added amlodipine besylate 5mg 1x daily. Is the combination?

Yes combination safe. Do you mean is combination safe? Yes. Cozaar (losartan) is an arb- working in your kidneys to keep blood pressure under control (and protect your kidneys) and the amlodipine is a calcium channel blocker, which works on your blood vessels and heart to control blood pressure and reduce cardiac workload. They work compatably to keep blood pressure under control.
