Dilantin: A Comprehensive Overview

Phenytoin, commonly known by its generic name Dilantin, is a medication used primarily to treat seizures and epilepsy. It belongs to the group of drugs called anti-epileptics and has been a trusted choice for managing seizures for decades.

Key Features of Dilantin:

  • Dilantin is the brand name for the drug phenytoin, which is classified as an anti-epileptic medication.
  • It is primarily prescribed for the treatment of seizures, including general tonic-clonic seizures, complex partial seizures, and seizures occurring during neurosurgery.
  • Dilantin works by slowing down brain impulses that cause seizures, thus preventing their occurrence.
  • It is available in various forms, including capsules, chewable tablets, suspensions, and injectable solutions.

How Does Dilantin Work?

Dilantin acts by stabilizing electrical activity in the brain, restoring a normal balance and preventing the spread of abnormal electrical activity that causes seizures. It accomplishes this by inhibiting the flow of sodium ions through specialized channels in the brain cells, known as voltage-gated sodium channels. By blocking these channels, Dilantin regulates the excessive firing of neurons, thereby reducing the occurrence of seizures.

“Phenytoin acts on the brain to reduce the occurrence of seizures by stabilizing electrical activity and preventing the spread of abnormal impulses.”

Usage and Dosage

When prescribed Dilantin, healthcare professionals should provide detailed instructions on usage and dosage. The dosage may vary based on each individual’s specific condition, medical history, and age. Generally, Dilantin is taken orally, usually in two to three divided doses throughout the day. It is essential to follow the prescribed schedule and not skip or alter doses without medical consultation.

Age Group Dosage
Adults 300-400 mg per day
Children (6-12 years) 4-5 mg/kg per day
Infants (0-5 years) 5 mg/kg per day

Possible Side Effects

In rare cases, it may lead to severe adverse reactions, such as an allergic reaction, liver damage, or blood disorders. It is crucial to promptly report any unusual symptoms to a healthcare professional.

“Although Dilantin generally has a good safety profile, it is important to be aware of potential side effects and to seek medical advice if any concerns arise.”
