I have been receiving the Octreotide injections (Sandostatin, and now lanreotide) for 11 years, every 28 days. The only side effects that I have noticed is that after my first shot 11 years ago, my blood sugar went up and I am now diabetic and deal with that on a daily basis. Other than that, I do not know of any other side effects. My liver and mesentary tumors have remained stable through these 11 years.
