How much dose of docetaxel do you use? Because one of the biggest side effects of this drug is leukopenia, it is generally necessary to use dexamethasone tablets for pretreatment, that is, the day before chemotherapy and the day after chemotherapy, it is necessary to take 10 dexamethasone tablets twice a day. The rule of his leukopenia is that it may decrease on the fifth day after chemotherapy, and it may decrease to a low point on the third and seventh days after chemotherapy. Everyone has his own law of reducing white blood cells. The more chemotherapy is carried out, the easier it is to reduce white blood cells. During chemotherapy, you should eat more foods containing high protein, such as pigeon soup and eel soup, and eat both soup and meat. Some Chinese patent medicines, such as Li Kejun, also have a slight effect on improving blood cells. But the most important thing is to use G-CSF preparation, that is, leukocytosis needle. Foreign countries suggest that preventive use is needed, that is, injection should be started on the fifth day after chemotherapy, and continuous injection should be carried out for 3-7 days regardless of whether the white blood cells are reduced at this time. If you haven't figured out the law of leukopenia, you can also start injection before leukopenia to avoid trough.
