How They Work



Anthelminthic drugs act in several ways. Many of them kill or paralyse the worms, which pass out of the body in the faeces. Others, which act systemically, are used to treat infection in the tissues.



Many anthelminthics are specific for particular worms, and the doctor must identify the worm before selecting the most appropriate treatment. Most of the common intestinal infestations are easily treated, often with only one or two doses of the drug. However, tissue infections may require more prolonged treatment.





How they affect you



Once the drug has eliminated the worms, symptoms caused by infestation rapidly disappear. Taken as a single dose or a short course, anthelminthics do not usually produce side effects. However, treatment can disturb the digestive system, causing abdominal pain, nausea, and vomiting.
