<One out of 10 men in the clinical trials developed blinding headaches that
grew more severe at higher doses. >>

Incidence and perhaps severity of side effects increase with the dose. In the clinical trials Pfizer tested up to 800mg., currently recommend a limit of 100mg. The company describes the headaches as "mild" and among those who dropped out of the study 2.5% dropped out because of side effects (all kinds) which is about the same number that dropped out of the placebo group because of side effects. They may have massaged the numbers. Who knows.

<<It seems to me, this headache combined with the other affects and inability
of Viagra to mix with other drugs such as nitroglycerine leaves a lot of the
ED market available for the likes of VVUS. >>

I have written perhaps thiry scrips for Viagra, or given out samples now that I have them, to new patients. I have refused one patient because he was on nitroglycerin. I don't know how you translate that into meaningful numbers for the market share. Nitro users may know they can't take it and aren't coming in to ask for it. They may be lying about it in order to get VIagra. They may actually forget that they take nitro once or twice a month when asked.

Colby...there was a special on MSNBC this weekend about Viagra...some pros/cons...also a phone in segment. One poor sole called in and explained that he went into convulsions after using Vaigra.
It was a conflict with some other med not nitro ...the combination lowered his blood preasure too low...

Just another example of conflicts with other meds and incomplete screening of patients before using Viagra....more potential Muse patients.
