Geri,
Richard should be getting an infusion of anti-emetics before the chemo.

There should be three bags hanging there. The large one is for glucose infusion, the 2 smaller ones are the chemo and the antiemetic. They should hydrate him first with the glucose, then the anti-emetic and finally the chemo.

According to the manufaturer of Zofran it is only effective 60% of the time and has a limited time span for effectiveness so Richard should have different anti-emetics to use. Zofran is typically good for about 5 days then you need to switch for a while. If he is too ill to keep anything down then there is always Compazine suppositories.

Chemo also does a number on the stomach so industrial strength Pepcid AC (Famatodine) is also necessary. The nausea thing is a tough issue. I never overcame it and they had to shorten my chemo protocol from 3 to 2 Cisplatin infusions.

Keep after the doctors for solutions.
