Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use RUKOBIA (Fostemsavir).
Heart rhythm: RUKOBIA (Fostemsavir) can cause changes to the normal rhythm of the heart, including an irregular heartbeat called QT prolongation, when more than the recommended dose is taken. QT prolongation is a serious life-threatening condition that can cause fainting, seizures, and sudden death.
People with heart failure, Angina, low potassium or magnesium levels, or those who are taking other medications that can cause changes to the heart rhythm, may be at risk of developing an irregular heartbeat. If you have heart problems, or you are taking other medications, discuss with your doctor how RUKOBIA (Fostemsavir) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of RUKOBIA (Fostemsavir), and whether any special monitoring is needed.
Hepatitis B and C: People who have hepatitis B or Hepatitis C may be more likely to experience decreased liver function and side effects involving the liver when they are taking RUKOBIA (Fostemsavir). If you have hepatitis B or C, discuss with your doctor how RUKOBIA (Fostemsavir) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of RUKOBIA (Fostemsavir), and whether any special monitoring is needed.
Immune reconstitution inflammatory syndrome: RUKOBIA (Fostemsavir) may cause immune reconstitution syndrome, where signs and symptoms of inflammation from previous infections appear. These symptoms occur soon after starting anti-HIV medication and can vary. They are thought to occur because of the immune system improving and being able to fight infections that have been present without symptoms (such as pneumonia, herpes or Tuberculosis). Report any new symptoms to your doctor immediately.
Stopping the medication: If you stop taking RUKOBIA (Fostemsavir), your HIV infection could get worse. Take the medication exactly as prescribed by your doctor and do not stop taking the medication without checking with your doctor first.
Pregnancy: RUKOBIA (Fostemsavir) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking RUKOBIA (Fostemsavir), contact your doctor immediately.
Breast-feeding: It is not known if RUKOBIA (Fostemsavir) passes into breast milk.Women with HIV infection are cautioned against breast-feeding because of the risk of passing HIV to a baby who does not have the infection, since the virus can be transmitted through breast milk.
Children: The safety and effectiveness of using RUKOBIA (Fostemsavir) have not been established for children.
