Lorbrena (lorlatinib) is an anticancer medication that's used to treat anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer (NSCLC) that has spread to other parts of the body. It’s a pill that you take by mouth, so it’s more convenient than an injection. Some common side effects Lorbrena (lorlatinib) might cause include swelling in the face or hands and feet, weight gain, or nerve pain.
Lorbrena (lorlatinib) is a targeted therapy anticancer medication that blocks a protein called anaplastic lymphoma kinase (ALK). The ALK protein is made by the ALK gene. This gene is something that everyone is born with. In people with ALK-positive NSCLC, this gene doesn’t work like it should. It ends up making abnormal proteins and causing cancer. Lorbrena (lorlatinib) works to block the ALK protein, so cancer cells can’t grow and spread as well.

Lorbrena (lorlatinib) 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.
During clinical trials, people who took Lorbrena (lorlatinib) while taking rifampin (Rifadin) at the same time experienced serious liver problems and had abnormal liver labs. This occurred as early as with their first dose of Lorbrena (lorlatinib). Typically, people saw their liver labs return to normal within a month after they stopped taking Lorbrena (lorlatinib).
Because of the risk of serious liver damage, you can’t take Lorbrena (lorlatinib) with other medications that can raise your risk of liver problems. Let your provider know of all medications (prescription and over-the-counter), vitamins, and herbal products you take so they can check for drug interactions.
About half of people who took Lorbrena (lorlatinib) in clinical trials experienced a wide range of side effects related to the brain. The most common side effects included problems with thinking and speech, changes in mood, and trouble sleeping. Less common, but more serious, side effects included delusions, hallucinations, and seizures. For most people, these problems typically started anywhere between a month to 3 years after they began Lorbrena (lorlatinib) treatment. Let your provider know if you develop any of these problems. Depending on how severe these problems are for you, your provider might temporarily stop Lorbrena (lorlatinib), lower your dose, or switch you to a different medication.
Lorbrena (lorlatinib) can raise the level of cholesterol and fat (triglycerides) in the blood. On average, people noticed this side effect about 2 weeks after starting treatment. Your provider will check your cholesterol or fat levels through lab work before you start treatment, for the first two months of treatment, and regularly after that. If the cholesterol or fat level in your blood gets too high, your provider might ask you to take medications to lower them. Depending on how high your blood cholesterol levels are, your provider might lower your dose of Lorbrena (lorlatinib).
Though uncommon, Lorbrena (lorlatinib) can cause a heart block (atrioventricular block), which can affect your heart beat. Your provider will monitor your heartbeat before your start treatment and periodically during treatment with an electrocardiogram (ECG). If you experience a blocked heartbeat your provider might consider placing a pacemaker, lowering your dose of Lorbrena (lorlatinib), or treating your cancer with a different medication. Let your provider know right away if you experience any symptoms of a problem with your heartbeat such as feeling dizzy or faint, or notice a change in your heartbeat.
Though not common, some people taking Lorbrena (lorlatinib) experienced serious lung problems, like inflammation of your lungs (pneumonitis) or interstitial lung disease. If you develop lung problems, your provider might ask you to stop taking Lorbrena (lorlatinib) permanently. Let your provider know right away if you start to have any new or worsening breathing problems (e.g., coughing, shortness of breath, or trouble breathing) or fever.
People taking Lorbrena (lorlatinib) can experience high blood pressure while taking the medication. This can happen right after you start treatment or as late as 3 years after you begin Lorbrena (lorlatinib). Your provider will check your blood pressure before you start taking Lorbrena (lorlatinib) and regularly throughout treatment. If your blood pressure is high, your provider might ask you to stop taking Lorbrena (lorlatinib) temporarily. And if it’s dangerously high, your provider might lower your dose of Lorbrena (lorlatinib) or switch you to a different medication. Let your provider know right away if you experience any symptoms of high blood pressure such as headaches, dizziness, blurry vision, chest pain, or trouble breathing.
The typical starting dose of Lorbrena (lorlatinib) is 100 mg taken by mouth once daily.
Your dose might be different if you’re taking an interacting medication or if you have severe kidney problems.
Contraindications are specific health conditions or situations in which a person should not take a medication due to safety concerns. If you have any of the following conditions or if any of the following apply to you, let your healthcare provider know because Lorbrena (lorlatinib) will not be safe for you to take.

Lorbrena works well to treat ALK-positive NSCLC and it’s one of the first-choice medications for this type of cancer. In a clinical trial of people newly diagnosed with NSCLC and haven’t yet received any anticancer treatment, Lorbrena lowered the risk of their cancer spreading by 72% compared with Xalkori (crizotinib), an older ALK-positive NSCLC medication. In addition, 71% of people who had NSCLC that spread to the brain (one of the common places where NSCLC tends to spread to) noticed their brain tumor disappear completely and not come back for at least a year after receiving Lorbrena, compared to only 12% after receiving Xalkori (crizotinib). If you have questions about how well Lorbrena works, talk with your provider.
You should take Lorbrena as instructed by your provider. How long you take Lorbrena treatment depends on several factors, including how well the medication is working to treat your cancer. It can also depend on if you develop any serious side effects like breathing problems or blocked heartbeat. Don’t stop taking Lorbrena without first discussing it with your provider.
No. Chemotherapy medications work by directly killing cancer cells in your body. Lorbrena isn’t a chemotherapy medication. Rather, it’s a type of targeted anticancer treatment. It works more specifically to target certain proteins that are involved in the growth of cancer cells. Typically, early NSCLC is treated with chemotherapy, while targeted therapy is used more often to treat lung cancer that has spread to other parts of the body. If you’ve been diagnosed with lung cancer, ask your provider what treatment options are appropriate for you.
Yes, taking Lorbrena can raise your cholesterol levels. Higher cholesterol levels is one of the most common side effects of this medication. Having high cholesterol levels can raise your risk for other medical conditions, such as heart problems and stroke. Your provider will check your cholesterol level before you begin Lorbrena, a month or two after you start treatment, then regularly after that. If your cholesterol level rises too high, your provider might prescribe medications to lower your cholesterol, or raise your dose of cholesterol-lowering medications if you’re already taking one. There are also lifestyle changes you can make to keep your cholesterol at a healthy level. For example, you can limit eating highly processed foods that are high in trans fat and sugar, such as fried foods, fruit juice, or soda. Another example is to build in at least 30 minutes of daily exercise into your routine. If you’re new to exercise, try starting with some light exercise, such as walking.
Let your provider know right away if you become pregnant while taking this medication. Based on animal studies, Lorbrena might cause harm to your unborn baby so it isn’t recommended during pregnancy. If you’re able to become pregnant, you should use birth control while taking Lorbrena and for 6 months after the last dose. Males with female partners who are able to become pregnant should use birth control while taking the medication and for at least 3 months after their last dose. If you have questions about future family planning and how Lorbrena can impact those plans, talk to your provider.
