Pregnancy Category: C
60 mg, 90 mg, 120 mg single-dose prefilled syringe
An analog of natural somatostatin produced by the hypothalamus. Somatostatin inhibits the secretion of growth hormone (GH)
that in turn inhibits secretion of insulin-like growth factor-1 (IGF-1).
Inhibition of IGF-1 suppresses proliferation of chondrocytes and stops bone growth.
Long-term treatment of acromegaly in those who have not responded to surgery and/or radiotherapy, or for whom surgery and/or
radiotherapy is not an option.
Treatment of symptoms, specifically diarrhea and cutaneous flushing, with carcinoid neuroendocrine tumors
Hypersensitivity to lanreotide; pregnancy (category C); lactation. Safety and efficacy in children have not been established.
Cholelithiasis, gallbladder disease; diabetes mellitus; moderate to severe renal impairment; moderate to severe hepatic
impairment; older adults.

Assessment & Drug Effects
- Monitor cardiovascular status as bradycardia and hypertension are potential adverse effects.
- Lab tests: Baseline and periodic GH, IGF-1, blood glucose; baseline LFTs and renal function tests; periodic thyroid function
tests, HCT & Hgb.
- Periodic gallbladder motility tests are recommended.
- Monitor diabetics for loss of glycemic control.
Patient & Family Education
- Ensure that proper technique for SC drug administration is utilized.
- Diabetics should monitor blood glucose values often as this drug may elevate or lower blood glucose.
- Report to physician severe pain in the upper, right area of the stomach/abdomen, along with nausea and vomiting. These symptoms
could indicate the presence of gallstones.
