Mebendazole is an antiparasitic medication widely used to treat infections caused by intestinal worms in humans. It is effective against a variety of helminths, including roundworms, hookworms, whipworms, and certain tapeworms. The drug works by inhibiting the worms’ ability to absorb glucose, effectively starving them and leading to their eventual death. Mebendazole 100 mg  is commonly prescribed for both adults and children, and its administration is often oral in the form of tablets or chewable tablets. For most infections, a single dose may be sufficient, but in cases of heavier infestations, longer courses may be necessary.  The medication is generally well-tolerated, with mild side effects such as abdominal pain, nausea, or diarrhea occasionally reported. It is important for patients to follow the prescribed dosage and duration to ensure complete eradication of the worms and prevent reinfection. Mebendazole can be used in community-wide deworming programs, especially in areas with high prevalence of parasitic infections. Its safety profile allows use in children over two years of age, although consultation with a healthcare provider is essential for pregnant or breastfeeding women. Overall, mebendazole is a safe, effective, and widely accessible treatment for common human intestinal worm infections.
