Some important COVID-19 news. I'll be brief
There have been a lot of studies about repurposing existing drugs to fight the coronavirus. These studies hold tremendous promise. Researchers who have tested these compounds have found a few that hold promise. But the were surprised to find that dextromethorphan, the cough suppressant found in Robitussin DM and Nyquil, actually aided in the replication of the coronavirus.
This was an animal study, so it might not be a problem in "real life." But the best choice, in my view, if to avoid dextromethorphan like the plague.
I've touted the non-narcotic drug benzonatate (Tessalon Pereles) before, but it is an outstanding cough suppressant. One front-line doctor has blogged that this is an excellent drug for treating the dry cough that comes with COVID-19. I also have had luck (for acid reflux cough) with over-the-counter Chloraseptic lozenges which contain benzocaine. The only choices I know of other than these are various opiods, which doctors are scared to death to prescribe. Pick your poison, just don't take dextromethorphan!
