The dosage of Temodar is calculated according to your weight.My fathers doctor always did it in front of us with his little calculator and of course I always double checked it(they are known to make many errors).
I hope that the care givers ask a lot of questions, and you should always have a pen and paper with you to record items the doctor tells you, also questions that you may have.
I purchased an organizer and I wrote everything down. It looks like a novel. I also let the doctor know from the start that I will be calling with questions and some days I did more than once. I had his cell phone, office, pager and e mail address. Remember, they work for you and it is about your loved ones life not the doctors.
