What is Hetrazan 100 mg?
Hetrazan 100 mg is an antiparasitic medication that contains Diethylcarbamazine citrate (DEC) as its active ingredient. It is primarily used for the treatment of filarial infections, which are caused by parasitic worms transmitted through mosquito bites. These infections affect the lymphatic system, skin, eyes, and lungs.
Diethylcarbamazine is recognized globally as a vital medication in the control and elimination of lymphatic filariasis (elephantiasis) and other parasitic worm diseases. Hetrazan works by killing both the juvenile (microfilariae) and adult worms in the bloodstream and tissues.

How to Take Hetrazan 100 mg?

It is important to complete the entire course of treatment even if your symptoms improve early, and avoid skipping doses to ensure complete elimination of the parasites from your body.
How Does Hetrazan Work?
Diethylcarbamazine works by disrupting the protective structure of parasites, which weakens them and makes them easier to eliminate.
It paralyzes and kills the microfilariae while also making the parasites more vulnerable to the body’s immune system. Once the worms are destroyed, the body naturally removes them, which helps reduce inflammation, swelling, and breathing difficulties, and also prevents long-term complications such as permanent enlargement of the limbs.
