Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... Chemotherapy drugs have a range of side-effects that depend on the type of medications used. Usually fast-dividing cells of the body, such as blood cells and the cells lining the mouth, stomach, and intestines are mostly affected. Chemotherapy drugs can have their side effects even months to years to develop. According to your symptoms you must have nausea vomiting like side effects which are very common. These side-effects can frequently be reduced or eliminated with antiemetic drugs such as domperiodone, ondansarton, etc. Self-care measures, such as eating frequent small meals and drinking clear liquids or ginger tea, are often recommended. In general, this is a temporary effect, and frequently resolves within a week of finishing treatment. Refer to your oncologist Hope this information helps
