It affects both the immature larvae (microfilariae) and, in some cases, adult worms by altering their outer surface and reducing their ability to survive in the bloodstream. This makes the parasites more vulnerable to the body's natural immune defenses, allowing immune cells to recognize and destroy them more effectively. As the number of parasites decreases, symptoms such as swelling, inflammation, fever, and discomfort gradually improve. Diethylcarbamazine should always be taken exactly as prescribed and the full treatment course should be completed to achieve the best results.
