What is Octreotide?

Octreotide injection is used to treat severe diarrhea and other symptoms that occur with certain intestinal tumors or metastatic carcinoid tumors (tumors that has already spread in the body). It does not cure the tumor but it helps the patient feel more comfortable.

Octreotide injection is also used to treat a condition called acromegaly, which is caused by too much growth hormone in the body. Too much growth hormone produced in adults causes the hands, feet, and parts of the face to become large, thick, and bulky. Other problems such as arthritis also can develop. Octreotide works by reducing the amount of growth hormone that is produced by the body.

Octreotide may also be used for other medical conditions as determined by your doctor.

Octreotide is available only with your doctor's prescription

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines.

Appropriate studies have not been performed on the relationship of age to the effects of the short-acting form of octreotide injection in the pediatric population. Safety and efficacy have not been demonstrated.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of the long-acting form of octreotide injection in children 6 to 17 years of age.

Although appropriate studies on the relationship of age to the effects of octreotide have not been performed in the geriatric population, geriatric-specific problems are not expected to limit the usefulness of octreotide injection in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving octreotide injection.
