Anzemet (dolasetron) is a medication used to prevent nausea and vomiting due to cancer medications (chemotherapy). It's used for adults and children 2 years and older. This medication is taken by mouth within 1 hour before chemotherapy.
Anzemet (dolasetron) is an antiemetic medication. It works by blocking the actions of serotonin in the part of your brain that causes nausea and vomiting. This helps you feel less nauseous and less of an urge to vomit.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

Anzemet (dolasetron) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Anzemet (dolasetron) can affect your heart rhythm, which can be serious and life-threatening. One example includes lengthening the time period from when the heart pumps and then relaxes. This is known as QT prolongation. Your risk for QT prolongation is higher if you have certain factors, including abnormal electrolyte levels, heart rhythm problems, or are taking other medications that cause heart rhythm problems, such as amiodarone (Pacerone) and ciprofloxacin (Cipro), among others.
To lower your risk, your provider will periodically monitor your heart and perform electrocardiograms (EKGs) to make sure your heart rhythm is normal. If you feel your chest pounding, have shortness of breath, have chest pain, or feel faint or lightheaded while taking Anzemet (dolasetron), call 911 right away.
Some people taking Anzemet (dolasetron) have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens where there's too much serotonin in the brain. Your risk for serotonin syndrome goes up if you use Anzemet (dolasetron) with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, pain medications, and migraine medications.
Let your provider know about all the medications you take before starting Anzemet (dolasetron). Also, don't start any new medications without talking to your provider first. Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Get medical help right away if you have any of these symptoms.
Some people have experienced a severe allergic reaction to Anzemet (dolasetron). These reactions can be life-threatening and include facial swelling, hives, and anaphylaxis (e.g., closing of the throat). If you notice dizziness, fast heartbeat, a choking sensation, difficulty breathing, swelling around your eyes, swelling of the lips or tongue, or any signs of a severe skin reaction after taking Anzemet (dolasetron), get medical attention right away.

In two studies looking at how well the medication works, 61% to 73% of people taking 100 mg of Anzemet before receiving chemotherapy had a complete response to Anzemet. This meant that they didn't experience any vomiting and didn't need any rescue medications for vomiting.
Anzemet is FDA approved to prevent nausea and vomiting only from certain chemotherapy. But some healthcare providers commonly use Anzemet and other similar medications for preventing nausea and vomiting from other things as well, such as surgery. Discuss with your provider if using Anzemet is an option to prevent nausea and vomiting for your particular situation.
No. The injection form of Anzemet is no longer available because it had a high risk of a severe, and even deadly, heart rhythm problem called QT prolongation. If you're having trouble swallowing the Anzemet tablets or having trouble keeping the tablets down, let your provider know. They can prescribe you a different medication such as ondansetron (Zofran), which is available in several formulations that might be easier to take.
Anzemet and ondansetron (Zofran) are similar medications that both work well to prevent nausea and vomiting from certain chemotherapy treatments. One major difference is that Anzemet is only available as a tablet, whereas ondansetron (Zofran) is available in many forms: a tablet that's taken by mouth, a tablet that's dissolved under the tongue, an oral liquid, and an injection. Another difference is that Anzemet is only available as a brand-name medication that can be expensive, whereas ondansetron (Zofran) is available as a lower-cost, generic form.
There haven't been enough studies looking at how Anzemet affects pregnant females or their unborn babies, so it's not known if it's safe to use during pregnancy. If you're pregnant or thinking of getting pregnant, talk to your provider about the risks and benefits of using Anzemet. In addition, this medication isn't FDA approved to help with pregnancy-related nausea and vomiting, so talk to your provider about your options to relieve morning sickness.
