Quercetin and Ivermectin

During the studies, scientists tried to use Quercetin and Ivermectin together.

But only in one study these two drugs were partially successful in the treatment of haemonchosis (Haemonchus contortus). It is a helminthiasis from the group of nematodes that appears in humans and animals. “The combination of Ivermectin and Quercetin was only effective for larvae with medium development,” the scientists concluded. The combination didn’t work on adult larvae.


Ivermectin and Quercetin are two different drugs successfully used in separate areas.
The effectiveness of their combined use, including for the treatment of COVID-19, has not been proven.
