Parasitic worm infections, also known as helminth infections, are commonly treated with antiparasitic medications. Drugs such as albendazole, mebendazole, and ivermectin are frequently prescribed depending on the type of worm. These medicines work by either killing the parasites or preventing them from absorbing nutrients. In some cases, supportive care such as iron supplements or improved nutrition may also be recommended to counteract anemia and malnutrition caused by the worms. For giardiasis and certain other parasitic infections, Nizonide 500 mg is often used. If you are seeking reliable sources, you can find a trusted nizonide 500 mg supplier online or through pharmacies.
