Lurbinectedin is a novel anticancer drug that has been approved for the treatment of metastatic small cell lung cancer (SCLC) in the European Union and some other countries [1]. As with any medication, lurbinectedin can cause side effects, which can be effectively managed with appropriate interventions and supportive care. Here, we will discuss some of the common side effects of lurbinectedin and evidence-based strategies to manage them.

Common side effects of lurbinectedin:
- Myelosuppression: Lurbinectedin can cause a decrease in the number of white blood cells, red blood cells, and platelets, leading to an increased risk of infections, anemia, and bleeding [1].
- Gastrointestinal toxicities: Nausea, vomiting, diarrhea, and constipation are common gastrointestinal side effects associated with lurbinectedin [1].
- Fatigue: Fatigue is a common side effect of lurbinectedin, which can impact the patient's quality of life and ability to perform daily activities [1].
- Hepatotoxicity: Lurbinectedin can cause elevations in liver enzymes, indicating potential liver damage [1].

Strategies to manage lurbinectedin side effects:
1. Myelosuppression:
- Monitoring complete blood counts (CBC) regularly can help identify myelosuppression early and allow for appropriate dose adjustments or treatment interruptions [1].
- Prophylactic use of granulocyte colony-stimulating factors (G-CSF) can reduce the risk of febrile neutropenia in patients receiving lurbinectedin [1].
- Antibiotics should be administered promptly if febrile neutropenia occurs [1].

2. Gastrointestinal toxicities:
- Antiemetic medications can be used prophylactically and as needed to manage nausea and vomiting [1].
- Loperamide or other antidiarrheal medications can be used to manage diarrhea [1].
- A high-fiber diet, stool softeners, and laxatives can help prevent and manage constipation [1].

3. Fatigue:
- Encouraging patients to maintain a healthy lifestyle, including regular exercise, a balanced diet, and adequate sleep, can help manage fatigue [1].
- Energy-conservation techniques and stress-reduction strategies can also be helpful [1].

4. Hepatotoxicity:
- Regular monitoring of liver enzymes can help identify hepatotoxicity early and allow for appropriate dose adjustments or treatment interruptions [1].
- In severe cases, corticosteroids or ursodeoxycholic acid may be considered [1].

In conclusion, lurbinectedin can cause various side effects, but they can be effectively managed with appropriate interventions and supportive care. Healthcare providers should closely monitor patients receiving lurbinectedin and use evidence-based strategies to manage side effects, ensuring optimal treatment outcomes and maintaining the patient's quality of life.
