http://www.medications.com/effect/view/28029 Cough which after several months subsided but my knees crack when I walk. Dr. says can't be meds but it didn't start until I went on the med. Quit taking them and cracking subsided. BP went to 225/102 so started taking again last week and knees are crack Thu, 17 Apr 2008 15:21:55 -0400 http://www.medications.com/effect/view/28029?item=7359 I would suggest you have the doc prescribe a different blood pressure medicine. Lisinopril is an ACE inhibitor and those are known to cause a persistent dry cough as a side effect although that usually comes with long-term use or high doses.
