Clinical information

Antiepileptic drug safety warning

Antiepileptic drugs (AEDs), including this medication, increase the risk of suicidal thoughts or behavior in patients taking them for any indication — not just epilepsy. Anyone starting or already taking an AED should be monitored for new or worsening depression, suicidal thoughts or behavior, or any unusual changes in mood. Contact your prescriber right away, or call or text 988 (Suicide & Crisis Lifeline), if these occur. Do not stop an AED abruptly without medical guidance — sudden discontinuation can trigger withdrawal seizures.

Narrow-therapeutic-index medication

This is a narrow-therapeutic-index medication. Do not switch between brand and generic manufacturers without close monitoring by your prescriber. Small differences in absorption can cause treatment failure or toxicity.

FAQ

Is generic Phenytoin the same as Dilantin?

Yes. The FDA requires generics to contain the same active ingredient at the same strength as the brand. Inactive ingredients (binders, dyes) may differ.

How much can I save by choosing the generic?

Currently no FDA-approved generic equivalent exists for Dilantin, so the brand and generic prices are similar.

Do I need insurance to get this price?

No. The prices shown on BetterBuyRx are cash prices. Often these beat insurance copays for generics.

How often is this price updated?

At minimum every 72 hours. Many sources refresh every few hours.
