Pharmacist tips for Everolimus (Zortress)
- Take everolimus (Zortress) at the same time as your other transplant medication (either cyclosporine (Sandimmune) or tacrolimus (Prograf)). You can take these with or without food, but stay consistent — always take them the same way.
- Take everolimus (Zortress) twice a day, about 12 hours apart to keep a steady level of medication in your body.
- Swallow the everolimus (Zortress) tablet whole with a glass of water. Don't crush or chew the tablet since this can affect how well it works.
- You'll need to have regular lab tests done while you're taking everolimus (Zortress). These tests help make sure the medication is working properly and that you aren’t having serious side effects. Follow your prescriber’s instructions and don’t skip any lab tests.
- Taking everolimus (Zortress) can weaken your immune system, raising your risk of infections. Watch for signs like fever, chills, cough, or feeling unusually tired. If you notice any symptoms of infection, contact your care team right away.
- Taking everolimus (Zortress) can raise your risk of developing certain cancers, especially skin cancer. To help protect yourself, limit your time in the sun and avoid ultraviolet light. When outdoors, wear protective clothing and use sunscreen.
- Everolimus (Zortress) interacts with many medications. Always check with your transplant provider before starting any new medication or supplement.
- Avoid grapefruit, pomelo, pomegranate, and Seville oranges while taking everolimus (Zortress). These citrus fruits and their juices can raise the level of the medication in your body, which can be very dangerous.
- While taking everolimus (Zortress), vaccines might not work as well, so you won't get full protection. Avoid live vaccines since they can raise your risk of infection. Talk to your prescriber before getting any vaccines while taking this medication.
- Talk to your transplant team about family planning. Everolimus (Zortress) can affect fertility and harm an unborn baby. People who can become pregnant should use birth control while taking everolimus (Zortress) and for 8 weeks after stopping the medication.
Risks and warnings for Everolimus (Zortress)
Everolimus (Zortress) 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.
Cancer
- Risk factors: Long-term use
Long-term use of everolimus (Zortress) raises your risk of developing lymphoma and other cancers, especially skin cancer. To protect your skin, limit sun exposure by wearing protective clothing and using sunscreen whenever you go outside. Talk to your prescriber if you have concerns about your cancer risk while taking this medication.
Serious infections
- Risk factors: Taking other immunosuppressants
Immunosuppressants like everolimus (Zortress) can raise your risk of bacterial, fungal, and viral infections. Some infections can be serious or even life-threatening. Your transplant provider might prescribe medications to help prevent certain types of infections to lower your risk of serious illness. If you develop symptoms of fever, chills, fatigue, muscle aches, cough, sore throat, runny or stuffy nose, tell your care team right away.
Kidney or liver blood clot
- Risk factors: Recent kidney or liver transplant (within 30 days)
Everolimus (Zortress) can raise your risk of developing a blood clot in the vessels of your transplanted kidney or liver, which could put your transplanted organ in danger. It's most likely to happen within the first 30 days after your transplant. Your transplant provider might order blood tests and scans to check for any signs of a clot.
Kidney damage
- Risk factors: Taking cyclosporine (Sandimmune) or tacrolimus (Prograf) | Taking other medications that can damage your kidneys
Taking everolimus (Zortress) with other anti-rejection medications like cyclosporine and tacrolimus can harm your kidneys. Since these medications must be used together, your transplant provider will adjust the doses to help protect your kidney function. Your care team will check your lab tests regularly to monitor your kidney health and make sure your medication levels stay safe.
Allergic reaction
- Risk factors: Taking ACE inhibitors
Everolimus (Zortress) has been linked to angioedema, a serious swelling that can affect your face, lips, or throat. Taking everolimus (Zortress) with certain blood pressure medications, like angiotensin-converting enzyme (ACE) inhibitors, can raise your risk of developing this side effect. Let your care team know if you notice any unusual swelling, especially if it makes it hard to breathe or swallow.
Slower wound healing and fluid build up
Everolimus (Zortress) can slow down wound healing and raise the risk of problems like infections and your incision opening up. Some of these issues might require additional surgery.
You might also have fluid buildup in different parts of your body, causing swelling in your arms and legs, or fluid around your heart, lungs, or stomach. Let your care team know if you notice unusual swelling, fluid retention, or any changes in how you feel.
Lung problems
Everolimus (Zortress) is linked to a lung condition called interstitial lung disease (ILD), which causes inflammation or scarring in the lungs. Let your prescriber know if you have symptoms like shortness of breath, cough, chest pain, or wheezing. Most people recover once they stop taking everolimus (Zortress), with or without additional treatment. But in rare cases, it can be very serious or even life-threatening.
High cholesterol and triglyceride
- Risk factors: High everolimus (Zortress) levels | History of high cholesterol
Taking everolimus (Zortress) can raise your cholesterol and triglyceride levels, especially if your everolimus (Zortress) levels in the blood are too high. Your prescriber will check your labs for any changes in your cholesterol levels. They might also recommend diet changes, exercise, or cholesterol-lowering medications. If you already have high cholesterol, your transplant provider will weigh the risks and benefits before starting or continuing this medication.
Diabetes after transplant
Everolimus (Zortress) can raise your risk of developing diabetes after a transplant. Your transplant provider will check your blood sugar levels closely while you're taking this medication. Let your care team know if you notice signs of high blood sugar, such as unusual thirst or hunger, frequent urination, blurred vision, or unusual tiredness.
Harm to unborn baby and fertility concerns
Everolimus (Zortress) can cause harm to an unborn baby if taken during pregnancy. If you can get pregnant, use birth control while taking this medication and keep taking it for 8 weeks after stopping treatment to prevent pregnancy. If you're pregnant or planning to become pregnant, talk to your prescriber about the risks.
Everolimus (Zortress) can lower sperm count, which can affect a person's ability to have children. This happens because the medication affects fast-growing cells, including those involved in sperm production. If you're planning to have children, discuss any fertility concerns with your prescriber before starting this medication.
Vaccines
Transplant medications like everolimus (Zortress) can change the way your immune system responds to vaccines. Avoid live vaccines while taking this medication because they can raise your risk of infection. If you need a vaccine while taking this medication, talk to your prescriber or pharmacist first to make sure it is safe for you.
