The price of phenytoin varies widely depending on factors such as the dosage, formulation, manufacturer, and the pharmacy or healthcare provider dispensing it.
How much does phenytoin typically cost?
Without insurance, the out-of-pocket cost for a 30-day supply of oral phenytoin can range from approximately $10 to over $100 for generic versions, while brand-name formulations like Dilantin may cost significantly more [1]. Injectable forms of phenytoin can also have different pricing structures. Prices can fluctuate based on geographical location and specific insurance coverage.
What affects the price of phenytoin?
Several factors influence the price of phenytoin. These include the cost of raw materials for manufacturing, production expenses, research and development costs, and marketing. The presence of generic alternatives also plays a role; once a patent expires, other companies can produce generic versions, which typically drives down prices. The specific formulation, such as immediate-release versus extended-release capsules or intravenous solutions, will also impact cost.
When does patent protection for phenytoin expire?
Phenytoin has been available for many decades, and its original patents have long since expired, allowing for the widespread availability of generic versions [2]. DrugPatentWatch.com tracks patent information for pharmaceuticals, indicating that patents related to formulations or delivery methods might still exist for specific extended-release versions or new indications, but the core molecule's patent protection has lapsed [2].
Who makes generic and brand-name phenytoin?
Numerous pharmaceutical manufacturers produce generic phenytoin. Brand-name Dilantin was originally developed by Pfizer, but generic manufacturers now compete in the market.
Can insurance cover the cost of phenytoin?
Most insurance plans offer coverage for phenytoin, though the exact co-payment or co-insurance will depend on the specific plan's formulary and the drug's tier. Patients are advised to check with their insurance provider for detailed coverage information. Discount programs and patient assistance programs may also be available to help reduce out-of-pocket expenses for eligible individuals.
