cough and nasal congestion
"I have had only one side effect that I can tell from it ... I have never had any stamina during sex, but after taking this medicine, I can last for an eternity the first time and then just have to stop during the second or third time because orgasm just don't come.  I am a 42 year old male and this is the second time this has happened.  The first time was about 7 or 8 years ago.  This is the truth and not a fabrication."
