Welcome to HCM
Amlodipine is a calcium channel blocker
antihypertensive drug, and Lisinopril is ACE inhibitor
. Overall both medicines are safe. In some susceptible persons reduction in blood count, or rarely sperm count
may occur. But lisinopril which is ACE inhibitor is safe drug. There are no major side effects reported except dry cough. Even very less chances of postural hypotension
. No reduction in sperm count reported in studies. So be assured and you can continue with lisinopril.
