Commonly used clinical medications to expel roundworms include albendazole, etc. Possible hazards or adverse reactions with the medication include dry mouth, headache, fever, etc. Possible adverse reactions or hazards of albendazole include thirst, decreased salivation, weakness, dizziness or headache, nausea, epigastric pain, and elevated ghrelin. These adverse reactions usually resolve when the drug is discontinued at the end of treatment. In case of serious adverse reactions, hospitalization is required and treatment needs to be discontinued if necessary. It should also be noted that the use of the drug is prohibited in combination with proteinuria, septic dermatitis, various acute diseases, severe hepatic, renal and cardiac impairment, active peptic ulcers, etc.; the use of the drug is prohibited before the surgical removal of worms in cysticercosis; and it is prohibited for pregnant women, breastfeeding females, as well as children under two years of age. In addition, mebendazole can be used for ascariasis, but the drug is not usually preferred; it is primarily used for the treatment of encapsulated worm disease, which has similar hazards or adverse effects as albendazole. Drugs such as albendazole need to be used under the supervision of a clinician, and prompt medical attention is recommended when parasitic infections are suspected.
