Phenytoin injection is used to control certain types of seizures (convulsions) in the treatment of epilepsy. It is also used to prevent and treat seizures that occur during brain surgery. This medicine is an anticonvulsant that works in the brain tissue to stop seizures.
This medicine is to be given only or under the direct supervision of a doctor.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of phenytoin injection in children.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of phenytoin injection in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require an adjustment in the dose for patients receiving phenytoin injection.
Sinus bradycardia (slow heartbeat)—Should not be used in patients with these conditions.
Your doctor will only give you or your child a few doses of this medicine until your condition improves. You will be switched to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
