Parasitic worm infections are treated with antiparasitic medications, depending on the type of worm. Common treatments include albendazole, mebendazole, and ivermectin. The nitazoxanide is another effective option, particularly for infections caused by Giardia and Cryptosporidium. It works by disrupting the energy production of parasites, leading to their elimination. Treatment duration varies based on the severity of the infection and the specific parasite involved. In addition to medication, maintaining good hygiene, proper sanitation, and avoiding contaminated food or water can help prevent reinfection. Consulting a healthcare professional is essential for accurate diagnosis and selecting the most appropriate treatment.
