Generic name: lanreotide (lan REE oh tide)
Brand name: Somatuline Depot
Drug class: Somatostatin and somatostatin analogs
Somatuline Depot (lanreotide) is a man-made protein similar to a hormone in the body called somatostatin. Lanreotide lowers many substances in the body such as insulin and glucagon (involved in regulating blood sugar), growth hormone, and chemicals that affect digestion.
Somatuline Depo is used in adults to treat:
- acromegaly that cannot be treated with surgery or radiation;
- carcinoid syndrome; or
- a certain type of pancreatic or digestive tract tumor that may spread to other parts of the body.
Somatuline Depo is sometimes given after other treatments have failed.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Especially tell your healthcare provider if you take:
- insulin or other diabetes medicines
- cyclosporine (Gengraf, Neoral, or Sandimmune)
- medicines that lower your heart rate such as beta blockers
