Risks and Side Effects
These are not all the risks and side effects of RUKOBIA, and this information does not replace talking with your healthcare provider about your medical conditions or treatment. For more information, talk to your doctor and refer to the Patient Information for RUKOBIA.
Who Should Not Take RUKOBIA?
Do not take RUKOBIA if you:
- are allergic to fostemsavir or any of the ingredients in RUKOBIA.
- take certain medicines, including: enzalutamide, carbamazepine, phenytoin, rifampin, mitotane, St. John’s wort (Hypericum perforatum).
What are the possible side effects of RUKOBIA?
RUKOBIA can cause serious side effects including:
- Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you start having new symptoms after you start taking RUKOBIA.
- Heart rhythm problems (QTc prolongation). RUKOBIA may cause a heart rhythm problem called QTc prolongation. QTc prolongation causes an irregular heartbeat. If you are elderly, you may be at a greater risk for developing this heart problem with RUKOBIA.
- Tell your healthcare provider right away if you feel dizzy, lightheaded, feel changes in your heartbeat, or you faint (lose consciousness).
- Changes in liver function blood tests results. People with HIV-1 who take RUKOBIA and who also have hepatitis B or C virus infections, may be more likely to develop new or worsening changes in certain liver function blood tests during treatment with RUKOBIA.
- If you stop your anti-hepatitis B treatment, this could mean that your hepatitis B may become active again (reactivated). Your healthcare provider may do blood tests to check your liver during treatment with RUKOBIA especially if you have hepatitis B virus infection.
- Take any anti-hepatitis B or anti-hepatitis C medicines as prescribed by your healthcare provider during treatment with RUKOBIA.
The most common side effect of RUKOBIA is nausea.
