Major

lopinavir ribociclib

Applies to: lopinavir / ritonavir and Kisqali (ribociclib)

Using ribociclib together with lopinavir can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). In addition, lopinavir may increase the blood levels of ribociclib. This can increase the risk of an irregular heart rhythm as well as other side effects such as nausea; vomiting; diarrhea; loss of appetite; mouth sores; abdominal pain, hair loss; weakness; headache; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you develop sudden or excessive drowsiness, dizziness, lightheadedness, fainting, confusion, shortness of breath, heart palpitations, bleeding problems, fever, or signs of infection during treatment with these medications, whether together or alone. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
