17  ANTHELMINTICS.
Drugs with a major effect of expelling or poisoning parasites are called anthelmintics. Anthelmintics are indicated for diseases caused by parasites in the intestines, such as ascariasis, enterobiasis, cestodiasis and ancylostomiasis. Anthelmintics should be selected for specific parasites and supplemented with other types of suitable drugs according to the actual condition. In cases accompaned with food stagnation, drugs for improving digestion and removing the stagnation should be added; in cases with concomitant constipation, purgatives should be given as well to help expel the parasites; if the disease is complicated by deficiency of the spleen and stomach, drugs for strengthening them should be prescribed in addition to the anthelmintics. Attention should be paid as follows: in using anthelmintics, administration of the drug on an empty stomach to ensure better effects; right dosage of poisonous drugs; temporary suspension of the drug in case of fever and severe abdominal pain; administration with caution for pregnant women, the aged and weak.
