viagra is not covered  by health insurance   doctor visit is     doctor gives prescription  however the viagra is not covered   its 15000  a pill    I think   there is a Korean medicine which is  generic to Viagra , I think Ciallis is used daily .  Viagra should be taken about an hour before activity .  Even with insurance viagra is not covered ,    Insurance is not a metter , Just see a doctor ,   In Korea Doctor fees are not expensive
