Many pharmacologic medications are available for the treatment of nausea. There is no medication that is clearly superior to other medications for all cases of nausea.  The choice of antiemetic medication may be based on the situation during which the person experiences nausea. For people with motion sickness and vertigo, antihistamines and anticholinergics such as meclizine and scopolamine are particularly effective.  Nausea and vomiting associated with migraine headaches respond best to dopamine antagonists such as metoclopramide , prochlorperazine , and chlorpromazine .  In cases of gastroenteritis, serotonin antagonists such as ondansetron were found to suppress nausea and vomiting, as well as reduce the need for IV fluid resuscitation.  The combination of pyridoxine and doxylamine is the first line treatment for pregnancy-related nausea and vomiting.  Dimenhydrinate is an inexpensive and effective over the counter medication for preventing postoperative nausea and vomiting.  Other factors to consider when choosing an antiemetic medication include the person's preference, side-effect profile, and cost.
This next page is a reposting of a flyer about a new book from . Smith and the Institute for Economic Democracy, whom I thank for their kind permission. The book is called Economic Democracy: The Political Struggle Of The 21st Century. Typically on this site, I do not advertise books etc, (although I will cite from and link to some, where relevant). However, in this case, I found that the text in the flyer provides an excellent summary of poverty's historic roots, as well as of the multitude of issues that cause poverty. (Please also note that I do not make any proceeds from the sale of this book in any way.)
