There is sufficient evidence that the two-drug combination may reduce the effect of the Coronavirus, particularly on older patients with any of the conditions that seem to otherwise have the effect of an increased mortality rate. While further testing is needed, were I to get the virus I'd definitely request those medications be added to my treatment just in case.
I already use one drug that was created for one condition but which works well for another. This is a very common occurrence in medical science.
The part I don't believe is that some doctors in Latin America believe that patients treated with that medication in the past for malaria will be immune to the new disease. Were that the case, I'd be home free...
I will speak with my doctor about taking the combo drugs. I am definitely in the high-risk group with three things going against me, age, diabetes and lung disease (I'm on oxygen 24/7).
I'll let my doctor determine whether the side effects of the drugs would be an acceptable risk for me.
