Immunotherapy is a medical treatment that stimulates your immune system to fight diseases like cancer. Side effects, also called immune-related adverse events (irAEs), can range from mild to severe and may affect different parts of the body (skin, gut, lungs, hormones, etc.)¹.

Managing immunotherapy side effects means proactively noticing symptoms, communicating with your care team, and using proven strategies to reduce discomfort, prevent complications, and keep your treatment on track.

• Improves quality of life: Addressing symptoms early means less time feeling unwell, more time enjoying daily life.
• Reduces risk of severe complications: Many side effects are easier to treat if caught early.
• Ensures you can continue immunotherapy treatment: Untreated side effects can interrupt or end your therapy.²
• Strengthens your mind-body wellness: Feeling supported helps reduce treatment anxiety and burnout.

Your proactive steps make a real difference!

• “Side effects are just part of the process—I have to tough it out.”
  Truth: Most side effects can be eased with the right care and communication.
• “If I talk about my side effects, my doctor might stop my treatment.”
  Truth: Reporting symptoms early often allows you to stay on treatment longer.
• “Immunotherapy is safer than chemo—there won’t be many side effects.”
  Truth: Side effects are different, but they can still be serious. Every treatment is unique.³
• “If I feel fine now, I’ll stay fine.”
  Truth: Some reactions appear weeks or months after treatment starts or even finishes.

1. Track your symptoms daily.
   Use a notebook or an app to record changes in your skin, digestion, mood, breathing, or energy. Even small changes can be important.
2. Communicate promptly with your medical team.
   Don’t wait for your next appointment—call your nurse or doctor if something feels “off.” Early intervention prevents big problems.
3. Follow your recommended care plan.
   This may include hydration, skin care routines, over-the-counter medications, or temporarily stopping treatment as advised.
4. Rest, hydrate, and eat nourishing foods.
   Your body is working hard; gentle, balanced nutrition and sleep can lessen fatigue and help recovery.
5. Manage stress constructively.
   Mindfulness, talk therapy, or relaxation exercises can build emotional resilience and reduce symptom flare-ups.⁴
6. Protect your skin.
   Use gentle cleansers, fragrance-free moisturizers, and wear sunscreen if going outdoors.
7. Seek professional help for emotional side effects.
   Reach out to a counselor, social worker, or support group.

• Integrate regular symptom checks: ASCO recommends patients use a symptom diary and bring it to every visit.²
• Respond swiftly to any new symptom, especially:
  • Shortness of breath
  • Yellowing of eyes/skin (jaundice)
  • Significant diarrhea or abdominal pain
  • New or worsening rash
• Ask about corticosteroids: These are commonly used to manage serious immune responses.³

• Journals or habit trackers: For mood, fatigue, and your daily health routine.
• Telehealth platforms (Some free, some paid): Secure messaging for quick access to your oncology team.
• Support groups: Check out American Cancer Society or local hospitals for programs.
