Hair thinning, fatigue, low blood pressure and heart rate, blood sugar spikes. I also started breast cancer meds that cause hair thinning and fatigue just two months before I started octreotide so it’s hard to know how much each med is responsible for. The side effects from octreotide are much better than the chronic coughing, mucous and shortness of breath that it alleviated so I don’t plan to stop octreotide as long as it’s effective.
