- Capillary Leak Syndrome (CLS). LUMOXITI can cause fluid to leak from small blood vessels into your body’s tissues. This condition is called “Capillary Leak Syndrome” (CLS). CLS can quickly cause you to have symptoms that may become life-threatening if not treated right away. Get emergency medical help right away if you develop any of the following symptoms of CLS:
- swelling of your face, arms, or legs
- fast weight gain (increase in 5.5 pounds from Day 1 of your current cycle)
- weakness or dizziness
- shortness of breath or trouble breathing
- low blood pressure
Your healthcare provider will check your weight and blood pressure before you receive each dose of LUMOXITI and as needed during treatment.
