昂丹司琼片一天吃几次,不良反应有哪些？

Nausea and vomiting caused by cytotoxic chemotherapy drugs and radiotherapy can be effectively suppressed or relieved by the application of ondansetron, which is a potent and highly selective serotonin 3 (5-HT3) receptor antagonist. It has a rapid and powerful inhibitory effect on vomiting caused by some chemotherapy drugs with strong emetogenic effects. So, how many times a day should ondansetron tablets be taken, and what are the adverse reactions?

How many times a day should ondansetron tablets be taken?

Ondansetron should be taken several times a day and according to the dosage prescribed by the doctor. Do not abuse the drug blindly. For vomiting caused by highly emetic chemotherapy drugs: Inject 8 mg of ondansetron injection intravenously 15 minutes before chemotherapy, 4 hours, and 8 hours after chemotherapy, and take 8 mg ondansetron tablets (2 tablets) orally every 8 to 12 hours after stopping chemotherapy for 5 days. The condition of the patient is different, and the usage and dosage will also change. For vomiting caused by chemotherapy drugs that are not very emetic: Inject 8 mg of ondansetron injection intravenously 15 minutes before chemotherapy, and then take 8 mg of ondansetron tablets orally every 8 to 12 hours for 5 days.

What are there

Ondansetron is used for different conditions, and the adverse reactions will be different. The adverse reactions caused by prevention of chemotherapy are mainly headache, discomfort/fatigue, constipation, and diarrhea. The adverse reactions of ondansetron used to prevent nausea and vomiting caused by radiation are headache, constipation, and diarrhea; headache and hypoxia are the adverse reactions caused by the prevention of postoperative nausea and vomiting. There are also some transient side effects, such as liver function damage, dry stool, headache, dizziness, tachycardia, and chest discomfort, which are rare. Patients should pay attention to their own reactions during medication. If they have intolerance, contact the doctor in time for symptomatic treatment.

Ondansetron is rapidly absorbed orally and has anxiolytic and diazepam effects on the central nervous system, which helps inhibit the excitement of the vomiting center. It can also enhance gastric emptying at antiemetic doses and help reduce nausea. The above is the content of how many times a day to take ondansetron tablets and what are the adverse reactions. I hope it can help you!
