Tranexamic acid overdosage-induced generalized seizure in renal failure

Abstract EN

We report a 45-year-old lady with chronic kidney disease stage 4 due to chronic tubulointerstial disease.

She was admitted to our center for severe anemia due to menorrhagia and deterioration of renal function.

She was infused three units of packed cells during a session of hemodialysis.

Tranexamic acid (TNA) 1 g 8-hourly was administered to her to control bleeding per vaginum.

Two hours after the sixth dose of TNA, she had an episode of generalized tonic clonic convulsions.

TNA was discontinued.

Investigations of the patient revealed no biochemical or structural central nervous system abnormalities that could have provoked the convulsions.

She did not require any further dialytic support.

She had no further episodes of convulsion till discharge and during the two months of follow-up.

Thus, the precipitating cause of convulsions was believed to be an overdose of TNA.
