Dolasetron Food Interactions
Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of dolasetron there are no specific foods that you must exclude from your diet when receiving dolasetron.
What is dolasetron?
Dolasetron blocks the actions of chemicals in the body that can trigger nausea and vomiting.
Dolasetron oral (taken by mouth) is used to prevent nausea and vomiting that may be caused by medicine to treat cancer (chemotherapy).
Dolasetron may also be used for purposes not listed in this medication guide.
Proper Use of dolasetron
Take dolasetron only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
If your child cannot swallow the tablets, the injection solution can be mixed with apple or apple-grape juice and taken by mouth. The mixture may be stored for up to 2 hours at room temperature before use.
The dose of dolasetron will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of dolasetron. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
- For oral dosage form (tablets):
- For prevention of nausea and vomiting after cancer medicines:
- Adults—100 milligrams (mg) given within 1 hour before starting cancer treatment.
- Children 2 to 16 years of age—Dose is based on body weight and must be determined by your doctor. The dose is usually 1.8 milligrams (mg) per kilogram (kg) of body weight given within 1 hour before starting cancer treatment. However, the dose is usually not more than 100 mg.
- Children younger than 2 years of age—Use and dose must be determined by your doctor.
- For prevention of nausea and vomiting after cancer medicines:
If you miss a dose of dolasetron, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
If you miss a dose of dolasetron, and you feel nauseated or you vomit, take the missed dose as soon as possible.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
