Phenytoin

Phenytoin is an antiepileptic medication used to control seizures in people with epilepsy. It belongs to a class of drugs known as hydantoin derivatives. This medication works by stabilizing the electrical activity in the brain, reducing the frequency and severity of seizures. Phenytoin is often prescribed for focal seizures (previously known as partial seizures), which involve a specific area of the brain, as well as generalized seizures that affect the entire brain. It is also sometimes used to prevent migraine headaches and manage certain types of abnormal heart rhythms. Phenytoin is available in tablet, capsule, and liquid forms, and its dosage and administration depend on the specific condition being treated and the individual patient’s needs. It is important to follow the healthcare provider’s instructions carefully and to monitor for any side effects, such as dizziness, drowsiness, or changes in mood. Regular blood tests are necessary to ensure that the medication is working effectively and to avoid potential toxicity.
