Phenytoin is a medication that is typically utilised as an anticonvulsant or antiepileptic medicine and is used to manage seizures. Other brand names for the medication include Dilantin and Eptoin. It functions by limiting the activity of brain stem areas and slowing down brain impulses. Despite the medicine's wide range of therapeutic applications, several side effects and drug interactions limit its use. A low dose may be ineffective in stopping a seizure, whereas a high concentration may cause a drop in blood pressure and other side effects. The test is typically performed to determine the drug's blood level so that the correct dosage can be administered.
