i understand that viagra & levitra are similar,
but that cialis works in a different way.

is there a risk if a man takes viagra or levitra
WITH cialis?  or can one take both types of medication
for "insurance" w/o much worry?

thanks!

Based on a review of the prescribing information and/or patient
information from the drugs' manufacturers, combining these medications
is certainly not recommended and could present various dangers.  Just
taking one product increases the risk of heart problems and damage to
the penis from prolonged erections.  I would think that combining
medications would have the potential to increase these risks, along
with creating a risk of additional dangers that are presently unknown.
 The maker of Viagra strongly states that it should not be used in
combination with any other treatments for erectile dysfunction,
including other medications.

Because combining these medications has not been studied, you would be
using yourself as a guinea pig to discover what risks may exist in
taking them together.  Personally, I wouldn't consider doing it.

Sincerely,

Wonko

appreciate the speed, and the references.  to be truthful, i was
*wishing* for an even more definitive answer ... and was tempted to
give 4 stars,instead of 5.  but then fairness took over, i realized
these were new medications, etc.  so -- truly -- five stars and a tip.
thanks.
