Every fourth patient experience nausea and vomiting (N/V) of varying degrees during chemotherapy treatment and a lot of patients feel it is the most painful and debilitating with cancer during treatment. Treatment of N/V is given as prevention and does not guarantee full protection for each patient. Complementary methods are used for both treatment and prevention of N/V. In fear of N/V, a lot of patients choose not to have chemotherapy or discontinue their chemotherapy treatment prematurely. Aim: The aim was to describe how complementary methods can relieve chemotherapy-induced N/V. Method: The study was a literature review and eleven scientific articles were analysed and compiled. Result: After compiling the results, the complementary methods could be divided into different categories; Stimuli, Diet and Activity. Discussion: There are complementary methods that relieve N/V during chemotherapy treatment. A combination of different complementary methods can prevent, reduce and/or relieve chemotherapy-induced N/V. However, the effect was not noticeable until a few days after initiation of chemotherapy. Anxiety before chemotherapy is associated with the degree and the presence of N/V and development of anticipatory N/V. Since nurses work must be performed after research-based- and experienced knowledge more research is needed to give strength to the complementary methods.
