This medication is a long-acting form of lanreotide. Lanreotide is used to treat a condition called acromegaly that occurs when the body makes too much of a certain natural substance called growth hormone. It is used when surgery or radiation treatment have not been fully successful or cannot be used. Treating acromegaly helps reduce the risk of serious problems such as diabetes and heart disease. Lanreotide works by decreasing the amount of growth hormone to normal levels.

This drug is not a cure for acromegaly. It is used for the long-term treatment of this condition.

This medication is also used to treat certain cancer or tumors of the stomach, intestines, or pancreas. It may help to slow down the growth of these tumors. Lanreotide is also used to treat carcinoid syndrome. It may help reduce the need to use another medication to treat diarrhea or flushing caused by carcinoid syndrome.

Read the Patient Information Leaflet if available from your pharmacist before you start using lanreotide and before each monthly injection. If you have any questions, ask your doctor or pharmacist.
