What is the most important information I should know about LORBRENA?

LORBRENA may cause serious side effects, including:

  • Liver problems due to interactions with other medicines. It is important to know what medicines should not be taken with LORBRENA.
  • Problems with brain (central nervous system [CNS]) function. Many patients experienced problems with brain function including problems with thinking (such as forgetfulness or confusion), mood (such as depression), speech, seeing or hearing things that are not real (hallucinations), and seizures during treatment with LORBRENA. In some patients, these problems are severe and your healthcare provider may need to have you stop taking LORBRENA.
  • Increases in the cholesterol and triglycerides (lipid) levels in your blood. Most patients will have an increase in the lipid levels in your blood during treatment with LORBRENA.
    • If you have increases in the lipid levels in your blood during treatment with LORBRENA, your healthcare provider may need to start you on a medicine to lower the levels. If you are already taking a medicine to lower the lipid levels in your blood, your healthcare provider may need to increase your dose of that medicine.
    • Your healthcare provider should do blood tests to check the lipid levels in your blood before starting treatment, 1 to 2 months after starting treatment, and during treatment with LORBRENA.
  • Heart problems. LORBRENA may cause very slow or abnormal heartbeats. Your healthcare provider should check your heart rhythm (electrocardiogram [EKG]) before starting and during treatment with LORBRENA. Tell your healthcare provider right away if you feel dizzy or faint or have abnormal heartbeats. In some patients, these problems are severe and your healthcare provider may need to have you stop taking LORBRENA or have a pacemaker placed.
  • Lung problems. LORBRENA may cause severe or life-threatening swelling (inflammation) of the lungs during treatment that can lead to death. Symptoms may be similar to those from lung cancer. Tell your healthcare provider right away if you have any new or worsening symptoms of lung problems, including trouble breathing, shortness of breath, cough, or fever.

In some patients, these problems are severe and your healthcare provider may need to have you stop taking LORBRENA. See "What are possible side effects of LORBRENA?" for more information about side effects.
