"can you tell me how many of those compete with alferons labeling??"
All of them.
Alferon was approved only for treating genital warts in the 1980's, and that remains its only on-label indication.
In the years after ISI received FDA approval for Alferon, ISI tried to promote Alferon for off-label uses. But, sadly, ISI's own human studies showed that there was zero advantage for Alferon vs more modern and cheaper interferon-alpha in head-to-head controlled human studies, so ISI gave up on Alferon and sold it in a fire sale.
Under HEB's ownership, Alferon sales were ridiculously poor, and HEB ceased sales in 2008.
HEB and HEB's pumpers have tried to trumpet potential off-label uses as well, but such sales never happened, and it would be foolish to expect it to happen in the future.
