Generic Dilantin

Currently, generic Dilantin products are available as phenytoin sodium 30 mg and 100 mg extended-release capsules, phenytoin suspension 125 mg per 5 mL, and phenytoin injections. While all generic Dilantin drugs are equivalent to the brand-name medication, it is recommended that you avoid switching from one brand of Dilantin or phenytoin to another (since even small changes in phenytoin levels in your blood can cause problems).

 

An Overview of Dilantin Generic

Dilantin® (phenytoin) is a prescription medication that is used to treat epilepsy. Specifically, it is approved to treat certain types of seizures (complex partial seizures and generalized tonic-clonic seizures) in people with epilepsy. It is also approved to prevent seizures during brain surgery.
 
Dilantin is manufactured by Pfizer. However, the patents for all Dilantin products have expired, and several products are available as generics.
