While breakthrough seizures can happen, having them every two to three months suggests his current treatment may need adjustment. He is taking Eptoin (phenytoin) to control seizures, alongside Nicardia retard (nifedipine), Pacitane (trihexyphenidyl), Deplatt A (aspirin/clopidogrel), and Atorva (atorvastatin) for his overall health. Sometimes, medication levels in the blood need checking, or doses require fine-tuning to achieve better control. Please consult his neurologist soon; they can safely review his regimen, check for any drug interactions, and adjust his plan to help keep him comfortable and seizure-free.
