nausea/vomiting, chemotherapy induced
"I am surprised this isn't oncologists "go to" drug.  After my first A/C infusion for breast cancer, I had severe nausea and vomiting immediately.  The doctor prescribed 25 mg promethazine orally and rectally(in case I couldn't hold down the pill).  All it did was make me sleep for hours, induce a migraine status headache, severe stomach pain/cramping, and I would still wake up vomiting.  Then my doctor prescribed Dronabinol 5mg.  It was a miracle drug.  The stomach pain, nausea and vomiting completely stopped.  It made me slightly tired in the beginning, but the feeling was more relaxed than tired therefore I could continue to function normally.  It also stimulated my appetite which is very important  for chemotherapy patient"
