Chemotherapy and Nausea and Vomiting
Chemotherapy is a type of drug therapy commonly used to treat cancer. It works by using chemicals that target and destroy fast-growing cells in the body, including cancer cells. However, chemotherapy can also damage healthy cells that grow quickly, such as those in your hair or in your digestive system.
Chemotherapy can cause vomiting as a side effect because of how it affects the digestive system. Vomiting happens when signals between the digestive system and the brain become unbalanced. Certain chemotherapy drugs, like cisplatin, can cause vomiting through both the digestive system and the brain.
Treatment:
- Doctors recommend using a mix of medicines, called anti-emetics, which help prevent or reduce nausea and vomiting. These medicines are used for both early and later stages of chemotherapy-related vomiting.
- Some common anti-emetics include:
- 5-HT3 blockers like ondansetron or palonosetron
- NK1 blockers like aprepitant or netupitant
- Glucocorticoids, such as dexamethasone.
If you experience vomiting as a side effect of chemotherapy or have concerns about managing it, it's important to talk to your doctor. They can give you personalized advice and recommend the right treatment options for your specific situation.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
