Is it better to take micardis or micardis HCT?

The only difference between Micardis and Micardis HCT is that the latter is a combination drug, comtaining both Micardis and Hydrochlorothiazide (otherwise known as HCT or HCTZ). HCT is a diuretic.

The only reason you would need to take Micardis HCT would be if you are already taking HCTZ, and it just cuts taking two pills down into one.
