Ms. Anderson - I am not a physician but a quick review of "off-label" uses for Levitra does show a use for the medication for a condition called pulmonary hypertension ( high blood pressure in the artery that carries blood to the lungs). You should consult your pulmonologist about this in order to find out if it has any benefits for breathing or whether your friend's father was getting other benefits from it.
