HUSNAJ (4 years ago):

I am 55 and started Losartan potassium 50mg with Concor 10mg ten days back and since that day I am suffering from severe itching on my scrotum and penis. The itch stays for 5-10 minutes and I am forced to rub both my scrotum and penis vigorusly which eventually takes me to masturbation.
