octreotide (injection)

Generic Name: octreotide (injection) (ok TREE oh tide)
Brand Name: SandoSTATIN, SandoSTATIN LAR Depot

What is octreotide?

Octreotide is a man-made protein that is similar to a hormone in the body called somatostatin. Octreotide lowers many substances in the body such as insulin and glucagon (involved in regulating blood sugar), growth hormone, and chemicals that affect digestion.

Octreotide is used to treat acromegaly. Octreotide is also used to reduce flushing episodes and watery diarrhea caused by cancerous tumors (carcinoid syndrome) or tumors called vasoactive intestinal peptide tumors (VIP adenomas).

Octreotide may also be used for purposes not listed in this medication guide.

What is the most important information I should know about octreotide?

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.

What should I discuss with my healthcare provider before using octreotide?

You should not use octreotide if you are allergic to it.

To make sure you can safely use octreotide, tell your doctor if you have any of these other conditions:

  • diabetes;

  • gallbladder disease;

  • heart disease, high blood pressure, or heart rhythm disorder;

  • thyroid problems;

  • pancreatitis;

  • liver disease; or

  • kidney disease (or if you are on dialysis).

Octreotide is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

Using octreotide can affect certain hormones that may make it easier for you to get pregnant, even if you were unable to get pregnant before. Talk to your doctor about using birth control to avoid unwanted pregnancy.

It is not known whether octreotide passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I use octreotide?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Octreotide is injected under the skin, or into a vein through an IV. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine. Be sure to follow the instructions for the exact type of octreotide your doctor has prescribed for you.

Store octreotide in the original carton in the refrigerator. Protect from light.

Octreotide should be at room temperature when you inject it. Take the medicine out of the refrigerator 30 to 60 minutes before preparing your dose. Do not heat the medicine. After mixing your dose, give the injection right away. Do not save it for later use.

Prepare your dose only when you are ready to give yourself an injection. Do not use octreotide if it has changed colors or has particles in it. Call your pharmacist for new medication.

Your care provider will show you the best places on your body to inject octreotide. Use a different place each time you give an injection. Do not inject into the same place two times in a row.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

While using octreotide, you may need frequent medical tests.

Each single-use ampul is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

If refrigeration is not available, you may store an unopened single-use ampul or multi-dose vial at room temperature for up to 14 days. Keep away from moisture and heat.

Throw away any medicine left in the multi-use vial after 14 days of use. Then start a new vial.

What happens if I miss a dose?

Call your doctor for instructions if you miss a dose of octreotide.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include severe upper stomach pain, diarrhea, weight loss, warmth or tingling, numbness or cold feeling, unexplained muscle pain, weakness, weak pulse, fainting, or slow breathing (breathing may stop).

What should I avoid while using octreotide?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

Octreotide side effects

Common side effects may include:

  • diarrhea, constipation;

  • vomiting, upset stomach;

Side Effects (complete list)

Octreotide dosing information

Usual Adult Dose for Carcinoid Tumor:

Initial dose: 100 to 600 mcg per day, IV or subcutaneously, in 2 to 4 divided doses

-The median daily dose was 450 mcg; mean daily dose was 300 mcg.
-Benefits were seen in doses from 50 mcg to 1500 mcg per day.
-Experience with doses above 750 mcg per day is limited.

Long-Acting depot formulation (Establish tolerability with short acting product for at least 2 weeks before using this formulation):
Initial dose: 20 mg, IM (intragluteally), at 4 week intervals, for 2 months; continue with dose of regular octreotide for at least 2 weeks (at same dose patient was on before the switch)
After 2 months:
-If symptoms are controlled, consider reducing dose to 10 mg every 4 weeks
-If symptoms are not adequately controlled, increase to 30 mg every 4 weeks
Maximum dose: 30 mg every 4 weeks

-Failure to continue dosing of regular octreotide during a switch to the long acting formulation may exacerbate symptoms; some patients require 3 to 4 weeks of concomitant dosing.

Use: Symptomatic treatment of patients with metastatic carcinoid tumors where it suppresses or inhibits the severe diarrhea and flushing episodes associated with the disease.

Usual Adult Dose for Vasoactive Intestinal Peptide Tumor:

Initial dose: 200 to 300 mcg per day, IV or subcutaneously, in 2 to 4 divided doses
Maintenance dose: 150 to 750 mcg per day
-Doses above 450 mcg per day are not usually required.

Long-Acting depot formulation (Establish tolerability with short acting product for at least 2 weeks before using this formulation):
Initial dose: 20 mg, IM (intragluteally), at 4 week intervals, for 2 months; continue with dose of regular octreotide for at least 2 weeks (at same dose patient was on before the switch)
After 2 months:
-If symptoms are controlled, consider reducing dose to 10 mg every 4 weeks
-If symptoms are not adequately controlled, increase to 30 mg every 4 weeks

-Adjust dose for therapeutic response.

Use: Long term treatment of the profuse watery diarrhea associated with Vasoactive Intestinal Peptide (VIP) secreting tumors.

Usual Adult Dose for Acromegaly:

Initial dose: 50 mcg, IV or subcutaneously, 3 times a day
Maintenance dose: Usually 100 mcg, 3 times a day
Maximum dose: 500 mcg, 3 times a day

-Starting at a low dose may help patients adapt to gastrointestinal adverse events.
-Use IGF-1 (somatomedin C) levels, every 2 weeks, to guide titration.
-Multiple growth hormone levels, zero to 8 hours after dosing, may permit more rapid dose titration.
-Doses over 300 mcg per day seldom provide additional biochemical benefit.

Long-Acting depot formulation (Establish tolerability with short acting product for at least 2 weeks before using this formulation):
Initial dose: 20 mg, IM (intragluteally), at 4 week intervals, for 3 months
After 3 months:
-If GH is 1 ng/mL or less, IGF-1 normal, and clinical symptoms controlled: 10 mg, IM, every 4 weeks
-If GH is 2.5 ng/mL or less and clinical symptoms controlled: 20 mg, IM, every 4 weeks
-If GH is higher than 2.5 ng/mL and/or clinical symptoms uncontrolled: 30 mg, IM, every 4 weeks
-If GH, IGF-1, or symptoms are not adequately controlled at 30 mg, may increase dose to 40 mg IM every 4 weeks
Maximum dose: 40 mg, every 4 weeks

-The goal is growth hormone (GH) levels under 5 ng/mL, or IGF-1 levels under 1.9 U/mL (male) or 2.2 U/mL (female).
-If increased doses do not provide additional benefit, reduce dose.
-Check IGF-1 or growth hormone levels every 6 months.
-For patients who have received irradiation: withdraw medication yearly for about 4 weeks (8 weeks for long-acting formulation) to assess disease activity; if growth hormone or IGF-1 increase and symptoms recur, resume therapy.

Use: To reduce blood levels of growth hormone and IGF-1 (somatomedin C) in acromegaly patients who have had inadequate response to or cannot be treated with surgical resection or radiotherapy.
