Could you be allergic to phenytoin?
Finding the right drug to treat epilepsy is always going to be tricky but doctors will always want to prescribe the safest and most beneficial drug for each patient, and these will differ from individual to individual. In some cases the side effects may cause more harm to the patients than the seizures themselves and they may increase the likelihood of non-adherence to the prescribed medication. So it is vital wherever possible, to be able to predict a person’s individual reaction to new medication.
New research from the Royal College of Surgeons in Ireland has developed a genetic test which can predict if a patient will develop an adverse reaction to phenytoin, one of the most commonly used antiepileptic drugs. You can read more about the research here
