Can you please let me know what test was done: Was it is Phenytoin
therapeutic level or toxic level? When was the blood sample taken in respect to your dose of medicine?
If the level of 38 is a therapeutic level, it means that the drug's level is well above the dose needed for preventing the seizures. it is good that you have been checked for side effects of high blood levels of Phenytoin. What this means is that the dose of Eptoin
can be brought down.
If you continue to have Seizure activity inspite of adequate Phenytoin, then your doctor needs to consider whether another medicine needs to be added. Which medicine this is depends on the type of epilepsy
that you suffer from.
Hope this helps?
