Severe reactions (including myoclonus, seizures, auditory and visual hallucinations, decreased mentation) have been reported with high-dose penicillin therapy or in patients with renal dysfunction.

CSF penicillin levels ranged from 12 to 61 units/mL in the seizure group with the highest CSF concentrations, compared to 7.8 units/mL in the group without seizures. Neurologic reactions occurred frequently in patients with renal dysfunction.
