Generic Monopril is used for treating high blood pressure. It may be used alone or with other blood pressure medicines. It may also be used with other medicines for the treatment of congestive heart failure. More info »
Regarding the effect: I do notice an increase in bloodflow and a better
stamina using the pills (I use 50mg). A side-effect I have noticed is that
my nose clogs up so I seem like I have a cold for an hour or so after taking
one pill. No other side-effects than that.
