Lurbinectedin is a medication used to treat patients with small cell lung cancer (SCLC) who have failed previous treatment. While it can be effective in treating cancer, it can also cause some side effects [2]. The most common side effects of lurbinectedin include fatigue, nausea, vomiting, decreased appetite, constipation, and diarrhea [2][3]. Patients may also experience hair loss, anemia, and changes in liver function tests [3]. Additionally, the medication can cause bone marrow suppression, which can lead to decreased white blood cell count, increased risk of infection, and decreased platelet count [2][3]. Patients may also experience electrolyte imbalances and an increased risk of bleeding [3]. In rare cases, lurbinectedin can cause severe hypersensitivity reactions, which can lead to anaphylaxis [2]. Patients should report any side effects to their healthcare provider immediately. It is important to note that not all patients will experience these side effects, and some may experience different side effects not listed here [3]. Overall, while lurbinectedin can be effective in treating SCLC, patients should be aware of the potential side effects and report any concerns to their healthcare provider [2][3].
