The starting dose of Dilantin ER (phenytoin extended-release) depends heavily on the individual’s condition and other medications they’re taking. Always follow your doctor’s instructions.
Adults with Epilepsy
For newly diagnosed adult epilepsy patients, the typical starting dose ranges from 300 to 400 mg daily. This is often given as a single dose, or divided into two doses. Your doctor will closely monitor your blood levels to adjust the dose based on your response and tolerance.
- Dosage adjustments are common. Expect regular blood tests. Never change your dosage without consulting your physician.
Adults with Other Conditions
For adults using Dilantin ER for other conditions (like certain arrhythmias), the starting dose varies greatly. Your doctor will determine the appropriate dose based on your specific needs and medical history.
Your doctor will meticulously assess your condition before prescribing. Blood tests are crucial to monitor therapy and prevent adverse effects.
Children
Dilantin ER is often not the first choice for children. If prescribed, the starting dose is significantly lower and is always carefully determined by a pediatric neurologist or other qualified specialist based on weight and other factors.
Important Considerations
- Accurate weight measurement is paramount for calculating the correct dosage for children. Concurrent medications significantly affect the metabolism of Dilantin ER; expect adjustments. Regularly scheduled blood tests help ensure the drug concentration remains within the therapeutic range.
Monitoring Treatment
Close monitoring of blood levels is key to ensure therapeutic effectiveness and minimize the risk of side effects. Regular check-ups with your physician are indispensable.
