Lanreotide - subcutaneous/intramuscular

Patient Medicine Information
Why do I need this medicine?
Lanreotide is used to treat acromegaly (a disorder where the body has a high level of growth hormone). This medicine helps by lowering the growth hormones in your body.

Lanreotide is also used to relieve symptoms associated with carcinoid tumours (a tumour that usually starts at the digestive tract).

This medicine may be used to treat other conditions as decided by your doctor.
How do I use this medicine?
Use Lanreotide exactly as directed by your doctor or according to the instructions on the label. Do not use more or less than instructed by your doctor.

This medicine is to be injected subcutaneously (into the fatty layer under the skin, usually in the thigh, upper arm or abdomen area). Your doctor or nurse will administer the injection for you.

If you are already eligible for self-administration of the pre-filled syringe preparation, follow these steps:
  1. Remove Lanreotide from the refrigerator and allow to reach room temperature for 30 minutes. Do not remove the pre-filled syringe from the sealed pouch unless it is already time for the injection.
  2. Wash your hands with soap and water.
  3. Choose an injection site. Usually injected in the upper, outer part of the thigh.
  4. Swab the injection site area with alcohol.
  5. Prepare the injection. Open the sealed pouch then remove the pre-filled syringe from its tray. Remove the needle cap by pulling it off. Do not touch the needle or push the plunger. Do not shake the pre-filled syringe or remove the cap until you are ready to inject.
  6. Flatten the injection area using your thumb and index finger to stretch the skin. Fully insert the needle perpendicularly (90° angle) using a strong and straight, dart-like action all the way into the skin. Once fully inserted, release the flattened area.
  7. Push the plunger with slow and constant pressure. The preparation is thick, it will take at least 20 seconds to deliver the full dose.
  8. Withdraw the needle from the injection site without releasing the pressure on the plunger. Once removed, release the pressure on the plunger. The needle will automatically retract into the needle guard.
  9. Apply gentle pressure over the injection site with a cotton ball or gauze pad to prevent bleeding.
  10. Dispose of the used syringe as instructed by your doctor or pharmacist. Do not throw away in household trash.
Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1.5 inches away from the previous injection site.

This medicine may also be administered to you via intramuscular (into the muscles) injection by your doctor or nurse.

The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your condition.
What should I do if I have forgotten to use this medicine?

If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
