octreotide (oral/injection)

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 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 (VIPomas).

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

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

Tell your doctor if you have ever had:

• 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).

Tell your doctor if you are pregnant or breastfeeding.

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.

How should I use octreotide?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Octreotide oral is taken by mouth.

Octreotide injection is injected under the skin, into a muscle, or as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

You may need to mix octreotide injection with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine.

Be sure to follow the instructions for the exact type of octreotide your doctor has prescribed for you.

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

Your healthcare provider will show you where 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.

You will need frequent medical tests.

If you need radiation treatment, you may need to stop using this medicine for a short time. Follow your doctor's instructions very carefully.

Take the ampul out of the refrigerator and let it reach room temperature before injecting your dose. Do not heat the ampul. Each ampul is for one use only. Throw it away after one use, even if there is still medicine left inside.

Once you begin using your injection pen, you may store it at room temperature for up to 28 days. Do not freeze, and throw the pen away if it has been frozen.

Throw the injection pen away 28 days after your first use, even if there is still medicine left inside.
