Yes, parasitic worm infections can be prevented through good hygiene, safe food practices, and medication when necessary. Washing hands regularly, drinking clean water, and properly cooking food help reduce the risk. In areas where infections are common, antiparasitic medications like Nizonide 500 mg may be prescribed as a preventive or treatment option. The nizonide 500 mg contains nitazoxanide, which is effective against various intestinal parasites. Regular deworming, especially in children, and avoiding contact with contaminated soil or feces also play a key role in prevention. Consult a healthcare provider before taking any medication for parasitic infections.
