Pasireotide Injection

Pasireotide injection (Signifor and Signifor LAR) is used to treat Cushing's disease (an abnormal condition that is caused by excess hormones [cortisol]) in adults who cannot be treated with surgery or who did not respond to surgery. Pasireotide injection (Signifor LAR) is also 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 or who did not respond to surgery. Pasireotide injection is in a class of medications called somatostatin agonists. It works by decreasing the amounts of cortisol produced by the body.

Pasireotide comes a solution (liquid) (Signifor) to be injected subcutaneously (under the skin). Pasireotide also comes as a suspension (liquid) (Signifor LAR) to be mixed with another solution and injected into the muscles of the buttocks by a doctor or nurse. Pasireotide solution (Signifor) is usually injected twice a day at home. It should be injected around the same times every day. Pasireotide suspension (Signifor LAR) is usually injected once every 4 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use pasireotide injection exactly as directed. Do not inject more or less of it or inject it more often than prescribed by your doctor.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Symptoms of overdose may include:

• diarrhea

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to pasireotide injection.

Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
