Lanreotide: Uses, How to Take It, and Side Effects

Published: July 26, 2026Updated: August 24, 2026

Lanreotide is a medicine that blocks certain hormones, including somatostatin. It is used to treat acromegaly and symptoms caused by certain neuroendocrine tumors, including carcinoid syndrome. It is available as a long-acting injection and, for some tumor-related uses, as an oral capsule.

Quick summary

Lanreotide can control hormone-related symptoms and tumor effects, but it may cause digestive problems and changes in blood sugar or heart rate. Take it exactly as prescribed and ask your doctor or pharmacist before making any changes.
