Fosphenytoin

Fosphenytoin is an anticonvulsant medication used to control and prevent seizures, particularly in emergency situations such as status epilepticus. It is a prodrug of phenytoin, meaning it is converted into phenytoin in the body to exert its therapeutic effects. Fosphenytoin is usually administered via injection and offers the benefit of faster onset and fewer local side effects compared to intravenous phenytoin. It is commonly used in hospitals to stabilize patients experiencing continuous seizures or when oral medications are not an option.

Uses of Fosphenytoin

• Treatment of status epilepticus
• Short-term management of seizures
• Seizure control during or after neurosurgery
• When oral phenytoin is not suitable

How Fosphenytoin works

Fosphenytoin is converted into phenytoin in the body, which stabilizes neuronal membranes by reducing repetitive firing of action potentials, helping control seizures effectively.

Benefits of Fosphenytoin

• Rapid control of seizures
• Useful in emergency settings
• Fewer injection site reactions
• Can be given intramuscularly or intravenously
• Effective for short-term seizure management

How to take Fosphenytoin

Fosphenytoin is usually given by a healthcare professional in a hospital setting through IV or IM injection. The dose is based on weight, seizure type, and response to treatment. It is converted to phenytoin in the body, and blood levels are often monitored to avoid toxicity. Do not self-administer or adjust dosage without medical advice.
