They can use the combo off-label. It would be good if they make sure that the overwhelmed doctors know about the possibility of a fatal complication, and also if they keep records in one registry of how the combo worked.

However -- to me there is NO reason to add any antibiotic that has an interaction. The biologist I talked to (who I mentioned in my previous post) theorized that they tried azithromycin because it's readily available and there are fewer people with allergies to it than have allergies to penicillin or sulfa.

But, azithromycin has that interaction.

Chloroquine BY ITSELF seems to have some efficacy against the virus.
It would be smart to use that, until Brilacidin or some other drug clears the testing phase and can be added to the mix.
