What Signifor is used for
Signifor is used to treat Cushing's Disease, a condition caused by an enlargement in the pituitary gland (pituitary adenoma, a benign tumour) which produces too much of a hormone called adrenocorticotropic hormone (ACTH). This overproduction of ACTH causes the body to produce too much of another hormone called cortisol. Too much cortisol leads to a variety of signs and symptoms such as weight gain with abdominal obesity, moon-shaped face, easy bruising, menstrual abnormalities, excessive body and facial hair, muscle wasting with generalized weakness and tiredness, depression and decreased libido. Signifor is designed to block the production of ACTH and therefore cortisol and help to reduce the symptoms caused by excess of cortisol.
Signifor contains pasireotide, a synthetic substance that mimics the action of somatostatin, a substance normally found in the human body, which can block the production of certain hormones such as ACTH. The advantage of pasireotide over somatostatin is that its effect is stronger and lasts longer.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.

Important Safety Information
- Always use new disposable needles and syringes every time you give yourself an injection.
- Use syringes and needles only once. NEVER share needles and syringes with someone else.
- Carefully inspect the ampoule prior to use. DO NOT USE if it is broken or if the liquid looks cloudy, coloured or contains particles. In all these cases, return the entire pack to the pharmacy.
- For sterility reasons, ampoules should be opened just prior to administration.
- This medicine is for single use in one patient only. Discard any residue.
Signifor is intended for subcutaneous use. This means that it is injected through a short needle into the fatty tissue just under the skin.
The injection site is the place on your body where you are going to give yourself the injection.
The TOP OF THIGHS and the ABDOMEN are recommended areas for subcutaneous injection. It is important to rotate the site of your injections, that is, you should choose a different site each time you inject.
You should also avoid injections at sites that are sore, where the skin is irritated, the navel, waistline, bruises and scars.
To reduce local discomfort, it is recommended that the solution should be at room temperature before injection.
Do not inject Signifor solution for injection into a vein or muscle.
PREPARING A DOSE
- Wash your hands thoroughly with soap and water.
- Take ampoule out of the box and carefully inspect the ampoule (as above).
- Read the label first. Check the dose on the ampoule is the dose your doctor has prescribed for you.
- Signifor solution for injection is filled in a break-off ampoule. The coloured dot on the top part marks the position of the breaking point on the neck of the ampoule.
TAP the ampoule with your finger in order to make sure there is no liquid in the top part when you open the ampoule.
- Recommended procedure:
Hold the ampoule in an upright position with the coloured dot facing away from you. Hold the base of the ampoule in one hand. Keeping your thumbs together above and below the neck, break off the top of the ampoule at the breaking point.
Once the ampoule is open, put it upright on a clean, flat surface.
- Take the sterile syringe and attach the needle to it.
If you have been told to use two needles, you should use the long thick blunt drawing up needle for this step.
Before you proceed to the next step, clean the injection site with an alcohol wipe or similar.
- Remove the cover from the needle. Put the needle into the ampoule and pull the plunger to draw up the entire contents of the ampoule into the syringe.
If you have been told to use two needles, you should now replace the long needle with the short giving needle.
- Hold the syringe in one hand between two fingers with your thumb at the bottom of the plunger. Tap the syringe with your fingers to get rid of air bubbles. Make sure there is no air bubble in the syringe by pressing the plunger until the first drop appears on the tip of the needle.
Do not let the needle touch anything. You are now ready to inject.
INJECTING A DOSE
- Gently pinch the skin at the injection site and holding the needle at an angle advised by your doctor or nurse, insert it into the skin.
- Keeping your skin pinched, slowly press down the plunger as far as it will go until all the solution is injected. Hold this position for 5 seconds.
- Slowly release the skin and gently pull the needle out.
IMPORTANT: If you injected yourself, put the cover back on the needle. If a carer has carried out the injection, they should not recap the needle in case of needle-stick injury.
- Dispose of every used syringe and needle immediately in a standard approved sharps container. Any unused medicine or waste material should be disposed of in a manner that meets local requirements. Your doctor or nurse can provide disposal information as well as your local council.
Seek advice if you plan to travel.
