What are the risks and warnings for Onivyde (liposomal irinotecan)?
Onivyde (liposomal irinotecan) 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.
Severely low white blood cell count (neutropenia)
Risk factors: Asian descent
Onivyde (liposomal irinotecan) can make you have dangerously low white blood cell counts. This is called neutropenia and can lead to life-threatening problems. When you don’t have enough white blood cells, it puts you at high risk of infection. Although rare, it also could put you at risk of serious fever or a serious condition called sepsis.
On day 1 and 8 of each treatment cycle with Onivyde (liposomal irinotecan), your oncology team will draw your blood to check your blood cell count. If needed, they might check more often. If your white blood cell count is too low or if you also have a fever, your oncologist will delay your infusion until you get better. They might also lower your dose for your next infusions if your blood counts get too low or if you get an infection.
Let your healthcare team know if you think you have an infection, especially if you have a fever. Sometimes, fever might be the only sign of an infection.
Severe diarrhea
Diarrhea is a common side effect of Onivyde (liposomal irinotecan). But it can sometimes be very serious and even life-threatening. Because of this risk, people with a blockage in their gut shouldn’t take Onivyde (liposomal irinotecan).
This severe diarrhea can happen soon after your infusion (within 24 hours) or later (a day or more after). Early diarrhea can also come with stomach cramps, runny nose, drooling, watery eyes, or sweating. Severe diarrhea can lead to problems, like dehydration and low electrolytes.
Be sure to stay hydrated. Tell your oncology team right away if you have any diarrhea at any time while taking Onivyde (liposomal irinotecan). Especially call them if you have vomiting or diarrhea that doesn’t go away or black or bloody stools. Also tell them if you have signs of dehydration like feeling dizzy, lightheaded, or faint. These can be signs of severe diarrhea and serious problems from it.
Your care team can recommend treatment depending on when the diarrhea happens. For example, they can give you a medication called atropine for early diarrhea. And they’ll have you take loperamide (Imodium A-D) for late diarrhea. Your oncologist will also decide to pause or stop taking Onivyde (liposomal irinotecan).
Lung damage
Risk factors: History of lung problems | Previous radiation therapy | Taking medications that can cause lung damage | Taking medications that help the body make more white blood cells (colony stimulating factors)
It’s rare, but Onivyde (liposomal irinotecan) can cause lung damage. This can sometimes be severe and even life-threatening.
Tell your oncologist about all your health problems, the treatments you’ve had, and the medications you take. Some things can make you more likely to have lung damage. If you’re at risk, your care team will check on you more often while you’re taking Onivyde (liposomal irinotecan).
Tell your care team right away if you have a new cough, a cough that gets worse, shortness of breath, or fevers. Your oncologist will probably have you stop taking Onivyde (liposomal irinotecan) while they check your lungs.
Severe allergic reaction
Onivyde (liposomal irinotecan) can cause severe allergic reactions, including anaphylaxis. This can look like dizziness, trouble breathing, swelling in your lips or tongue, itching, or hives.
If you think you’re having an allergic reaction, get medical help right away. If the reaction is very severe, your care team will change your treatment plan.
Harm to an unborn baby
Onivyde (liposomal irinotecan) has the potential to harm an unborn baby if it’s given during pregnancy. Before starting treatment, let your oncologist know if you’re pregnant. They can help explain the risks.
If you’re able to become pregnant, use effective birth control while taking Onivyde (liposomal irinotecan). Keep using birth control for at least 7 months after your last dose. If you’re male and can father a child, use condoms while taking this medication and for 4 months after your last dose.
