This might come under the heading of news you didn't want to hear:

Aviation physicians recommend that a pilot refrain from
operating an aircraft for six hours after taking Viagra. This is
especially true if he intends to fly at night. Of course, this also
means that a pilot should definitely not use Viagra to enhance his
performance while joining the "mile high club," in which membership
is achieved by sexual activity a mile above the earth. The
combination of a sexual exertion at a 5,000 foot altitude at night
could prove a deadly combination for a pilot and his loved one.

Courtesy of the Aero-News Propwash newsletter, which notes that the
risks are especially high if the pilot is over 65.

Aero-News is wrong about the reason pilots are not supposed to take Viagra
at night. Despite early rumors when the product was first introduced, it has
not been shown to increase anyone's risk of a heart attack. There is nothing
about sexual exertion at night that is any different than sexual exertion
during the day.

Viagra can cause a blue color shift in your vision. Ordinarily not dangerous
or even particularly annoying, but tests showed some pilots had difficulty
distinguishing runway lights from taxiway lights.
