Sandostatin (Generic Octreotide Injection)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Octreotide immediate-release injection is used to decrease the amount of growth hormone (a natural substance) produced by people with acromegaly (condition in which the body produces too much growth hormone, causing enlargement of the hands, feet, and facial features; joint pain; and other symptoms) who cannot be treated with surgery, radiation, or another medication. Octreotide immediate-release injection is also used to control diarrhea and flushing caused by carcinoid tumors (slow-growing tumors that release natural substances that can cause symptoms) and vasoactive intestinal peptide secreting adenomas (VIP-omas; tumors that form in the pancreas and release natural substances that can cause symptoms). Octreotide long-acting injection is used to control acromegaly, carcinoid tumors, and VIP-omas in people who have been successfully treated with octreotide injection but prefer to receive injections less often. Octreotide injection is in a class of medications called octapeptides. It works by decreasing the amounts of certain natural substances produced by the body.
How should this medicine be used?
Octreotide comes as an immediate-release solution (liquid) for injection to be injected subcutaneously (under the skin) or intravenously (into a vein) Octreotide also comes as a long-acting injection to be injected into the muscles of the buttocks by a doctor or nurse. Octreotide immediate-release injection is usually injected 2 to 4 times a day. Octreotide long-acting injection is usually injected once every 4 weeks. Inject octreotide immediate-release injection at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Inject octreotide injection exactly as directed. Do not inject more or less of it or inject it more often than prescribed by your doctor.
If you are not already being treated with octreotide injection, you will begin your treatment with immediate-release octreotide injection. You will be treated with the immediate-release injection for 2 weeks, and your doctor may gradually increase your dose during that time. If the medication works for you and does not cause severe side effects, your doctor may give you the long-acting injection after 2 weeks. In order to control your condition, you may need to continue to receive the immediate-release injection for 2 weeks or longer after you receive your first dose of the long-acting injection. Your doctor may increase or decrease your dose of the long-acting injection 2 or 3 months after you first receive it.
If you are being treated for a carcinoid tumor or VIP-oma, you may experience worsening of your symptoms from time to time during your treatment. If this happens, your doctor may tell you to use the immediate-release injection for a few days until your symptoms are controlled.
If you have acromegaly and have been treated with radiation therapy, your doctor will probably tell you not to use octreotide immediate-release injection for 4 weeks every year or not to receive the octreotide long-acting injection for 8 weeks every year. This will allow your doctor to see how the radiation therapy has affected your condition and decide whether you should still be treated with octreotide.
