Praziquantel (applies to praziquantel) epilepsy

Major Potential Hazard, Moderate plausibility. Applicable conditions: Seizures

Praziquantel can exacerbate central nervous system pathology due to schistosomiasis. As a general rule this drug should not be administered in individuals with a history of epilepsy or seizures and any other signs of potential central nervous system involvement such as subcutaneous nodules suggestive of cysticercosis.

Praziquantel (applies to praziquantel) liver impairment

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

Caution should be exercised when administering praziquantel at the usual recommended doses in patients with moderate to severe liver impairment (Child Pugh class B and C). Reduced metabolism of praziquantel may lead to considerably higher and longer lasting plasma concentrations of the unmetabolized drug.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
