The appropriate dosage of ondansetron will depend on various factors such as the individual’s age, weight, medical history, and the cause of their nausea and vomiting. The usual recommended dosage for adults is 8mg to be taken 30 minutes before chemotherapy or radiation therapy and repeated every 8 hours for 1-2 days after treatment, or as directed by a healthcare professional. In some cases, a lower dosage may be recommended, especially for elderly patients or those with liver or kidney problems.
It is important to follow the dosage instructions provided by a healthcare professional and not to exceed the recommended dose without medical supervision, as high doses of ondansetron can cause serious side effects such as headache, dizziness, and irregular heartbeat. If any side effects occur or worsen, it is important to seek medical attention immediately. It is also important to inform a doctor or pharmacist of any other medications being taken, as some medications may interact with ondansetron.
