Fosphenytoin, sold under the brand name Cerebyx among others, is a medication used to treat status epilepticus and prevent seizures. It may be used instead of phenytoin in those who cannot take medication by mouth. It is given by injection into a vein or muscle.

Common side effects include dizziness, nystagmus, itchiness, numbness, sleepiness, and poor coordination. Other side effects may include low blood pressure, QT prolongation, Stevens-Johnson syndrome, angioedema, and liver problems. Use in pregnancy may harm the baby. It is a prodrug of phenytoin and works by blocking sodium channels.

Fosphenytoin was approved for medical use in the United States in 1996. It is available as a generic medication. In the United Kingdom a 750 mg vial costs the NHS about £40. In the United States this amount costs about 24 USD.
