Hello @genovaldi and welcome to the NETs support group on Mayo Connect. There is an article on this topic from Mayo Clinic. Here is a quote:

"This medicine may increase your risk for heart and blood vessel problems, including hypertension and a slow heartbeat. This may cause chest pain or discomfort, headaches, dizziness, or blurred vision. You might need to measure your blood pressure at home. If you think your blood pressure is too high or if your heartbeat is too slow, call your doctor right away."
