Is Cardizem safe to be taken while on Phenobarbital and Dilantin?
Patient: I am presently taking phenobarbital and dilantin to control seizures. Newly prescribed blood pressure medications (Diovan, then Cardizem) both seem to react negatively and leave me weak and wobbly. Seizure control is old (prescribed back in the 1960s). What would be a more up-to-date regimen? Doctor: Hello Welcome to Ask a Doctor service I have reviewed your query and here is my advice.It is not the drug  causing you anything but it is just your doubt and if this is so then you can discuss this with your physician but it is not the drug causing the anything nonspecific you are thinking,  it seems to be the functional factors playing the role behind the symptoms you are having.Hope I have answered your query, let me know for further assistance.
