Injections of the medications octreotide (Sandostatin) and lanreotide (Somatuline Depot) may reduce the signs and symptoms of carcinoid syndrome, including skin flushing and diarrhea. A drug called telotristat (Xermelo) can be combined with these drugs to control diarrhea caused by carcinoid syndrome.
