Phenytoin Test (Dilantin or Eptoin)

Phenytoin, also known by its brand names Dilantin and Eptoin, is a medication commonly used to treat seizures. A phenytoin test, also known as a Dilantin or Eptoin test, is a blood test that measures the level of phenytoin in the blood.

The test is used to monitor phenytoin therapy and ensure that the drug is being dosed appropriately. Phenytoin levels that are too low can result in seizures, while levels that are too high can cause toxicity and side effects such as dizziness, confusion, and coordination problems.

The phenytoin test is also used to determine whether a person is taking the medication as prescribed and to diagnose toxicity in people who may have accidentally or intentionally taken an overdose of the drug.
