Like all medications, ipilimumab can cause side effects. Common side effects include fatigue, diarrhea, itching, and rash. More serious side effects can occur due to the enhanced immune response, leading to inflammation in various organs such as the intestines, liver, skin, and endocrine glands. These can result in colitis, hepatitis, dermatitis, and endocrinopathies, respectively. It's essential for patients to be closely monitored and for healthcare providers to manage these side effects promptly.
