Okay, my opinion on nausea meds: 1) Zofran--8 mg ODT, it is important that they are the dissolvable ODT kind...do not bother with the tablets! I would not go above 8 mg...they tried to keep increasing my dosage at one point when Zofran stopped being effective...increasing beyond a certain point can be dangerous...using in high amounts for chemotherapy is different because they use a high amount and then none at all for day....in your son's case it would be chronic use. 2) Kytril Patch (Sancusco) If Zofran is sort of working but not well enough, it might be worth it to try Kytril a similar med, in patch form. However, keep in mind that the patch is expensive. 3) Domperidone can be very useful, and is generally safer than Reglan. HOWEVER, make sure you check with a cardiologist. Dangerous QT prolongation can occur and is why I had to stop taking domperidone..although domperidone was fairly effective for me. 4) Benadryl--will worsen motility big time... but can be effective for nausea, and is safe. 5) Anzemet--wouldn't bother with if Zofran and Kytril didn't work. It was even more expensive, and not that effective. 6) Klonopin--.125-.25 dissolvable wafers can be VERY effective for nausea (can use Ativan instead, although in my opinion Ativan has more side effects) 7) Emend--this is what I'm going to try next...no idea about it yet, but I have been told that it is extremely effective although expensive 8) Marinol--haven't heard too many good things, but haven't tried it myself 9) Eythromycin in a VERY small dose 10) Phenergan, Compazine...these are older, sedating and can have nasty side effects, however for some people can be extremely helpful.
