Can BCG treatments cause nausea indefinetly?

BCG (Bacillus Calmette-Guerin) treatments, commonly used for bladder cancer, can cause side effects such as nausea. While nausea is a common response, it typically resolves after treatment and does not usually persist indefinitely. However, individual reactions can vary, and some patients may experience prolonged side effects. It's important for patients to discuss any ongoing symptoms with their healthcare provider for appropriate management.
