Curative treatment of congenital toxoplasmosis is based on the association of pyrimethamine and sulfonamide. There is currently no pediatric galenic formulation. We report the case of a newborn child affected by asymptomatic congenital toxoplasmosis who received an overdose of pyrimethamine. The patient received a dose of pyrimethamine 4 times, equal to 100 times the recommended dose, due to an error in the prescription. He had partial seizures 48 h after the last medicinal absorption. We noted a lack of appetite and vomiting, with a favorable progression in 5 days. Blood analysis showed isolated, spontaneously regressive moderate cholestasis. We propose a pharmacological clarification on the treatment of congenital toxoplasmosis.
