Ondansetron helps most people with nausea and vomiting, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
a sensation of warmth or flushing
mild stomach cramps
constipation or diarrhoea
dizziness or light-headed feeling
The above list includes the more common side effects of your medicine.
If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
chest pain or tightness of chest
changes in the way your heart beats e.g. if you notice it beating faster or slower than normal, or if it beats irregularly or if it ‘throbs’
disturbance in heart rhythm (sometimes causing a sudden loss of consciousness)
low blood pressure
abnormal muscular body movements or shaking
involuntary upward movement of the eyes
unusual muscle tone causing distortion of the body
fits or convulsions
patients may experience “serotonin syndrome” (confusion, sweating, unsteadiness, shaking, diarrhoea) when ondansetron is taken in combination with other serotonergic drugs. Serotonergic drugs can include certain types of antidepressants, opioid pain medicines such as tramadol and fentanyl, and lithium
severe skin reaction where the top layer of the skin detaches from the lower layers
symptoms of an allergic reaction including cough, shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin
The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.
If your nausea (feeling of sickness) or vomiting does not go away, ask your doctor what to do.
In certain illnesses and treatments where ondansetron has been used, blood vessel blockage has occurred.
However, it is important to note that blood vessel blockage has also occurred in these illnesses and treatments when ondansetron has NOT been used. Discuss this with your doctor if you have any concerns.
Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
Other side effects not listed above may also occur in some people.
Some of these side effects (for example blood pressure) can only be found when your doctor does tests from time to time to check your progress.
