Chewable Dilantin tablets come in one strength -- Dilantin 50 mg Infatabs. Liquid Dilantin also comes in one strength – Dilantin-125 suspension, containing 125 mg per 5 mL (125 mg per teaspoonful).
Dilantin injection is also available, although it is rarely used. In fact, it is used so rarely that the brand-name version of Dilantin injection is no longer being made (although generic versions are still available).
This medication is available in generic form (see Generic Dilantin).
