What is a common side effect of praziquantel?

Praziquantel is an anthelmintic medication widely used to treat infections caused by various types of parasites, including trematodes (flukes) and cestodes (tapeworms). A common side effect associated with its use is nausea and vomiting. This occurs as the drug acts on the parasites, leading to their disintegration within the host, and can trigger gastrointestinal symptoms in some patients. Considering the mechanism of action and the body’s response to the drug, nausea and vomiting are among the most frequently reported adverse effects, reflecting the distress some individuals may experience during treatment.

The other potential side effects, while possible, do not occur as commonly with praziquantel. For instance, dizziness, severe headache, and skin rash can also occur but are less frequently reported compared to nausea and vomiting. Recognizing these common side effects is crucial for managing patient expectations and ensuring proper care during treatment with praziquantel.
