Take Shudan before or after meals? (Ondansetron Hydrochloride) The instruction manual does not specify whether Shudan should be taken before or after meals. Instead, the medication time should be determined according to the patient's specific treatment time.

Shudan (ondansetron hydrochloride) is administered via intravenous or intramuscular injection, and the dosage can be flexibly controlled.

Shudan (ondansetron hydrochloride) is used for vomiting caused by chemotherapy and radiotherapy: the dosage and route of administration should depend on the severity of nausea and vomiting caused by chemotherapy and radiotherapy.

(1) Adults: ① For vomiting caused by highly emetic chemotherapy drugs: 8 mg of intravenous central tablets 15 minutes before chemotherapy, 4 hours, and 8 hours after chemotherapy, and 8 mg of ondansetron tablets (2 tablets) taken orally every 8-12 hours after stopping chemotherapy for 5 days. ② For vomiting caused by chemotherapy drugs that are not very emetic: take 8 mg of Shudan (2 tablets) intravenously 15 minutes before chemotherapy, and then take 8 mg of Shudan (2 tablets) orally every 8-12 hours for 5 days. ③ For vomiting caused by radiotherapy: the first dose of 8 mg tablets (2 tablets) must be taken orally 1-2 hours before radiotherapy, and 8 mg (2 tablets) taken every 8 hours thereafter. The course of treatment depends on the course of radiotherapy. ④ For the prevention of nausea and vomiting after surgery: Inject 4mg (1 tube) intravenously at the same time during anesthesia. ⑤ For high-dose cisplatin, 20 mg of dexamethasone sodium phosphate can be added intravenously before chemotherapy, which can enhance the efficacy of Shudan on vomiting caused by highly emetic chemotherapy.

(2) Children: Inject intravenously at a dose of 5 mg/m2 (body surface area) before chemotherapy, and then take it orally 12 hours later; after chemotherapy, oral administration should be continued for 5 days.
