Can Darzalex or Velcade cause sudden sleepiness during activities?
Fatigue is a common side effect of myeloma medications, including chemotherapy drugs. The extreme exhaustion from myeloma treatment is different from regular tiredness—it can't always be resolved with rest and may cause you to suddenly lose focus or fall asleep during activities.
A MyMyelomaTeam member shared experiencing "a variety of side effects from my myeloma medications," including dizziness. Another mentioned that changing medications can trigger various side effects.
Several factors could contribute to your sudden sleepiness:
* Fatigue from the medications themselves
* Anemia, which is very common in myeloma and causes extreme tiredness
* The combination of treatments affecting your energy levels
* Emotional stress and sleep disturbances from managing myeloma
The extreme exhaustion you're experiencing might also come with trouble concentrating or feeling dizzy. It's important to discuss these symptoms with your oncology team, as they may be able to adjust your medication timing or dosage, or check for anemia that might need treatment.
Regarding your skin issues, dry patches and itching can occur with myeloma treatments. Your healthcare provider should know about these symptoms too, as they may have solutions to help manage them.
