Is there an advantage in taking both ivermectin and hydroxychloroquine together for cancer treatment and would that be safe? Or would it be better to try one for a period of time and then switch to the other if there is no apparent symptomatic relief?

We think concomitant use of both agents would be tolerated by most patients and is a better way to serve them, given the overlapping but somewhat individual range of properties and benefits. The combined use would provide an advantage in terms of efficacy compared to sequential administration of one drug after the other, for cancer treatment.
