Phenytoin 50mg

Phenytoin 50mg Uses

How Does Phenytoin 50mg Work

Phenytoin stabilizes the activity of neurons in the brain by reducing abnormal electrical discharges. It blocks voltage-gated sodium channels in the neurons, preventing excessive nerve firing and helping to control seizures effectively.

• Swallow the capsule whole with water, with or without food.
• Maintain a consistent dosing schedule by taking the medication at the same time each day for optimal seizure control.
• Do not stop taking Phenytoin abruptly, as this may lead to increased seizure activity.
