What side effects does Yervoy (ipilimumab) cause?
Yervoy can cause a range of side effects, including immune-related effects that can involve the skin, intestines, liver, lungs, and other organs. These reactions can happen during treatment or after doses stop.
Because the type and severity of side effects depend on how your immune system responds, clinicians often monitor closely and may hold or stop Yervoy and start steroids or other immune-suppressing treatments if significant immune side effects occur.
What immune-related side effects should patients watch for?
Patients are commonly counseled to watch for symptoms that could signal inflammation from an overactive immune response, such as:
- Skin: rash, itching, blistering or peeling
- Intestines: diarrhea or abdominal pain (can indicate colitis)
- Liver: yellowing of skin/eyes or dark urine (hepatitis)
- Lungs: new or worsening cough, shortness of breath (pneumonitis)
- Hormones/endocrine glands: severe fatigue, headaches, dizziness, low blood pressure, or changes in weight (can reflect inflammation of pituitary or other endocrine organs)
- Other: severe weakness or neurologic symptoms, or unusual pain/swelling
If any of these symptoms occur, patients should contact their care team promptly, because early treatment can reduce the risk of complications.
Are the side effects different when Yervoy is used with Opdivo (nivolumab)?
Yes. When Yervoy is used in combination regimens (commonly with nivolumab), the overall rate and types of side effects can differ from single-agent treatment, and immune-related adverse events may be more frequent. Patients should follow the same symptom-monitoring guidance but with heightened awareness.
How serious can Yervoy side effects be?
Some Yervoy side effects are mild, but immune-related adverse events can be serious and sometimes life-threatening. Clinicians typically manage these by:
- stopping or holding Yervoy during evaluation
- giving corticosteroids when immune inflammation is suspected
- using additional immune-suppressing therapy for steroid-refractory cases
What should I ask my oncologist about before starting Yervoy?
People often ask:
- Which immune-related side effects you want me to watch for most closely in my specific case
- When and how to report symptoms (and which symptoms should trigger urgent calls)
- What tests you’ll monitor during treatment (for example, labs for liver function and endocrine effects)
- Whether I should have a plan for managing diarrhea, rash, or breathing symptoms quickly
