My cardiologist and family doctor gave me an prescription from right source for lisinopril Tab 20 MG. The instructions say , take 1/2 tablet every day.. The pills they sent me are practically impossible to split in half. I been trying to do this using a lot of tools (including a pill cutter) and they are tough and if I have a half size (10 MG0 pill left the other side of pill is a bunch of crumbles, left over, Can I get a 10 MG lisonopril pill made in the USA. Thanks, Jack Hornburg.. My E mail address is, YYYY@YYYY .
