  • you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness), including angioedema caused by treatment with an ACE inhibitor, or you are unable to urinate
  • you are also taking dofetilide or ketanserin
  • you are in your second or third trimester of pregnancy

Contact your doctor or health care provider right away if any of these apply to you.
