Who makes dilantin?

Who manufactures Dilantin (phenytoin) today?

Dilantin (phenytoin) is manufactured by multiple companies depending on the country and specific formulation (brand vs. generic). In the United States, Dilantin is available as a brand drug and is also widely supplied as generic phenytoin, with different manufacturers producing the generic versions.

How to tell which company made your specific bottle?

To identify the manufacturer for the exact product you have, check the package label for:
- “Manufacturer” (or “Distributed by”)
- The company name listed next to the National Drug Code (NDC)
- Whether it is “Dilantin” (brand) or “phenytoin” (generic)

Does patent or brand status affect who makes it?

Dilantin is an older medicine with generic competition, so “who makes it” can vary by whether you’re asking about:
- The original brand supplier for Dilantin in your market
- Any of the current generic manufacturers for phenytoin

If you tell me your country (and whether your bottle says Dilantin or generic phenytoin, plus the NDC if you have it), I can narrow down the likely manufacturer for your exact product.
