Great question! Teclistamab (Tecvayli) is a treatment for multiple myeloma, and many people have shared their experiences with it. Here's a summary of what MyMyelomaTeam members and clinical studies have reported.
Common side effects include:
- Fatigue, headaches, and fever
- Upper respiratory symptoms (like colds)
- Injection-site reactions
- Dropping white blood cell counts
- Increased infection risk (including pneumonia and shingles) More serious side effects to watch for:
- Cytokine release syndrome (CRS) — This can cause fever, chills, and breathing problems, especially during the first doses
- Infections — This is a major concern throughout treatment
- Low blood cell counts — Requires close monitoring
One MyMyelomaTeam member shared: *"I soon started having headaches and upper respiratory symptoms, which are side effects of the drug."* Tips from MyMyelomaTeam members:
- Expect extra hospital monitoring during the first step-up doses
- Track all side effects and report them to your doctor promptly
- Get regular blood work done and follow your counts closely
- Ask your doctor about adjusting injection frequency over time — some members moved from weekly to every 3–4 weeks
Always keep your care team informed about any new or worsening symptoms. 💙
