Chemotherapy-Induced Nausea and Vomiting

Chemotherapy-Induced Nausea and Vomiting

What is chemotherapy-induced nausea and vomiting?

Chemotherapy is one of the most common forms of treatment for a wide variety of cancers and it can be highly effective. However, it also comes with a range of unpleasant side effects, including chemotherapy-induced nausea and vomiting. Roughly 75% of all cancer patients experience these side effects. 

It comes in five different forms: 

  • Acute, where it occurs less than 24 hours after chemotherapy
  • Delayed, where it occurs between one to five days after chemotherapy
  • Anticipatory, which refers to chemotherapy-induced nausea and vomiting that progresses unhindered until the next round of chemotherapy
  • Breakthrough, where  it occurs despite treatment
  • Refractory, where it occurs during subsequent cycles of chemotherapy when antiemetics have failed in earlier cycles

What are the symptoms of chemotherapy-induced nausea and vomiting?

The key symptoms of chemotherapy-induced nausea and vomiting are of course the nausea and vomiting themselves. However, they can also have a variety of knock-on symptoms as well. These include:

  • Sweating
  • Malnutrition
  • Fatigue
  • Loss of appetite
  • Diarrhoea
risk-factors

What causes chemotherapy-induced nausea and vomiting?

There are specific types of chemotherapy drugs that induce nausea and vomiting at a higher risk. These include:

  • Anthracyclines, such as doxorubicin and epirubicin
  • Cyclophosphamide
  • Dacarbarbazine
  • The nitrosourea family, such as lomustine, carmustine, and streptozotocin
  • Platinum-based chemotherapy, such as cisplatin, carboplatin, and oxaliplatin

The reason they trigger nausea and vomiting is that they stimulate hormones and different receptors in the body that result in vomiting coming about as a defence mechanism. The body is responding to certain chemicals in the medications that cause nausea as a side effect.

treatments

What treatment options are available for chemotherapy-induced nausea and vomiting?

Oncological experts and doctors often prescribe extra medications to counteract chemotherapy-induced nausea and vomiting. These include:

  • Serotonin receptor antagonists, such as ondansetron, granisetron, palonosetron
  • Dexamethasone and aprepitant
  • Other classes of anti-sickness medications, including over-the-counter medication
  • Natural remedies, such as ginger

It can also be useful to try out different behavioural practices, such as avoiding particularly rich or spicy foods, or certain foods and drinks that may trigger nausea. These trigger foods can be different from person to person, so it’s also handy to keep a food diary so you can track what foods cause different reactions in the body.

How can medical cannabis help with chemotherapy-induced nausea and vomiting?

Considering how important it is for cancer patients to have energy and retain nutrients from their food, it’s vital to do everything we can to combat chemotherapy-induced nausea and vomiting. Medical cannabis is an alternative route for cancer patients that has been known to help.

This study from 2015, ‘Cannabis-based medicine for nausea and vomiting in people treated with chemotherapy for cancer’, by L.A. Smith, F.Azariah, V.T.C. Lavender, N.S. Stoner, and S. Bettiol showed a decrease in symptoms of chemotherapy-induced nausea and vomiting. It was especially effective in patients with low to moderate levels of nausea and vomiting.
