It's a CONSTIPATION drug!!!
I for one am happy that it might in a small percentage of cases cause severe diarrhea. That means it works!
Do you think the makers of Viagra complained when the FDA said they MUST put out a warning to "contact your physician if you experience an erection lasting more than four hours"? Their marketing department could have worked for years and never come up with anything near as effective for advertising!
Thank you FDA, and please, pretty please, would you force us to put that disclaimer on our label and in all our commercials?
