Hi Paul. I think going back on the Decadron could definitely help you.
My husband was diagnosed 4/07/07 with inoperable GBM IV. Standard radiation (34 treatments) while at the same time taking 160 mg of Temodar each day. Unfortunately, post rad MRI showed progression. So instead of putting him on the higher dose of Temodar as was the plan, they immediately started him on Avastin and CPT-11.
We've been up and down on the steroids. He's never been able to get off them. When he has been tapered down low on the Decadron, his side effects from the treatment worsen considerably. More nausea, no appetite and sleeping 18-20 hours a day. Back up on the Decadron and things improve.
In Feb. we tapered him down to 1.5 mg of the Decadron and the docs added 30 mg. of Cortef (a hydrocortisone) per day. I give him 1 mg. of decadron in the morning, along with 20 mg. of Cortef and 5 mg. of Ritalin. He was also getting another 5 mg. of Ritalin at noon. At 4;30 he takes .50 of the Decadron and 10 mg. of the Cortef. The idea was to get him on the hydrocortisone and then remove the Decadron. Well, he had his appt. in the Brain Tumor Clinic at Duke last Wednesday following another good MRI. I discussed the Decadron, hydrocortisone and Ritalin doses with the doctor and physicians asst. I told them I knew that he was doing as well as he is due to the decadron and hydrocortisone. Their response was "then let's leave the doses as they are." "Why rock the boat?" The only thing we cut out was the noontime dose of Ritalin.
They explained that the hydrocortisone is like a tiny steroid. So, your doc is correct in that some people can never get off the Decadron. We've been so fortunate that my husband has tolerated the Decadron ok. No really bad moods from it. Well, that's not entirely true - he sometimes has less patience and can't tolerate a lot of stress, chaos, noise and confusion in his life, but overall the decadron has been an immense help. I cannot imagine where we would be without it. Sure, his legs are skinny and his arms are too, but his overall quality of life is pretty darn good. He gets somewhat nauseated the day he gets his Avastin / CPT-11 infusions. He doesn't want much to eat that day, but he has been bouncing back within a couple of days.
So far, so good. It's a roller coaster and that's for sure.
I hope they can get your meds adjusted so that you too will get to feeling better.
Best to you,
Barb
