Ondar is available in form of tablet, syrup, and injection. It should be taken as per your doctor's instructions. Ideally, Ondar has to be taken with food to avoid stomach upset. The initial dose is usually taken half an hour before chemotherapy, 1 to 2 hours before radiation therapy and 1 hour before a surgery. Additional doses can be suggested by the doctor as per the individual requirements.

Yes, Ondar can be taken with pantoprazole as there are no records of any drug interaction. Pantoprazole is a proton pump inhibitor which is used for treating acidity. Acidity can be managed by avoiding eating acidic and spicy foods, avoiding smoking, and avoiding sleep within 3 hours of taking meals.

It is not recommended that you discontinue taking Ondar on your own. Discontinuing Ondar may lead to unwanted side effects of chemotherapy and radiation therapy such as excessive vomiting. You must speak to your doctor first as this will help you to take an informed decision.
