Parasitic worm infections can be treated with various antiparasitic medications, depending on the type of worm involved. Common options include albendazole, mebendazole, and ivermectin, which work by killing or paralyzing the parasites. For certain protozoal and worm infections, nizonide 500 mg (nitazoxanide) may be prescribed, as it is effective against a broad range of intestinal parasites. Treatment usually involves oral medication taken for a specific duration, sometimes alongside hygiene measures to prevent reinfection. In severe cases, follow-up stool tests are performed to confirm parasite clearance. Early diagnosis and proper treatment are essential to avoid complications and ensure complete recovery.
