Dilantin generic and brand name?

What are the generic and brand names for Dilantin?

Dilantin is the brand name for phenytoin, an anti-seizure medicine. The generic name is phenytoin. [1]

Is “Dilantin” the same drug as generic phenytoin?

Yes. Generic phenytoin products are intended to be the same active ingredient as brand Dilantin (phenytoin), typically in the same dosage forms/strengths approved by regulators. [1]

What should I look for on the prescription?

If the prescription says:
- “Dilantin,” it is the brand phenytoin product.
- “Phenytoin” (generic), it will be one of the approved generic phenytoin products. [1]

Why might there be different versions even though the name is the same?

Phenytoin is available in different formulations (commonly extended-release forms vs immediate-release forms). The label may specify a formulation type in addition to “phenytoin” or “Dilantin.” That formulation detail matters because it affects how the medicine releases and absorbs in the body. [1]
