Our bottom line

Azor (Amlodipine / Olmesartan) is good for lowering blood pressure since it contains two medications that act in different ways to keep your pressure under control.


  • It's a combination of two medications in one pill, so it reduces the amount of pills you have to take each day.
  • As a combination of two medications for high blood pressure, it works better than either by itself.
  • Taken only once a day.


  • Only available in a fixed combination, so it's hard to change the doses of either medication on its own.
  • If you become pregnant, your doctor will need to change the medication since it can cause birth defects.
  • Even though Azor (Amlodipine / Olmesartan) works well, it's usually not the first choice for treating high blood pressure since doctors often try other medications on their own before giving you two (in one pill) right away.
  • Can't be used with simvastatin (Zocor), a cholesterol lowering medication.
  • Only available as brand medication, so it can be somewhat pricey.
