The treatment of CVS is difficult area, with little or no research to support one form of treatment over another. Treatment often progresses in an empirical manner, by trial and error on an individual basis.
 
Treatment is supportive. During an episode it is often helpful to provide a dark, quiet environment. Intravenous fluids may be needed if the sufferer has become dehydrated, early use and monitoring are essential. Treatment with a range of anti-emetic and other drugs has been used, an individual may find a treatment that works for them, but there is nothing approaching a universal treatment regime. Between episodes a variety of treatments have been tried. Some can work well for some individuals, reducing frequency, duration or severity of an episode, but the same drug may provide no benefit to others. In most cases the evidence is anecdotal, relying on the opinion of the sufferer or parent, or the doctor. With the increasing use of potent drugs, such as chemotherapeutic agents to fight cancer, the problem of induced vomiting also increased. Many cancer patients suffer severe vomiting in response to treatment. This has led to research and development of better anti-emetic drugs. Use in CVS is quite common, but generally ad hoc, without trials to test the true effectiveness.
 
 
To provide specific treatment regimes here might not be helpful, we will develop this site to include personal case histories, where the complexities of treatment may be better explained.
