What Signifor LAR is used for

Signifor LAR is a prescription medicine used to treat patients with acromegaly.

Acromegaly is caused by an enlargement in the pituitary gland (a gland at the base of the brain) called a pituitary adenoma. This leads the body to produce too much of a hormone called growth hormone (GH). This overproduction of GH causes the body to produce too much of another hormone called insulin-like growth factor-1 (IGF-1). Normally, these hormones control growth of tissues, organs and bones.

Signifor LAR is a medicine containing a synthetic substance called pasireotide that mimics the action of somatostatin, a substance normally found in the human body, which can block the production of hormones such as GH and IGF-1. Signifor LAR is used instead of somatostatin because its effects are stronger and last longer.

Signifor LAR binds to somatostatin receptors which are present in high number in the brain in the pituitary gland where the excessive amount of growth hormone is produced. By binding to these somatostatin receptors, Signifor LAR reduces the production of GH and IGF-1 and may reduce the size of the adenoma.

Too much GH or IGF-1 leads to an increase in the size of bones and tissues, especially in the hands and feet.

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.

Signifor LAR is to be administered by the physician or healthcare professional only.

How Signifor LAR is given

Your doctor or nurse will inject Signifor LAR into your buttocks.

The site of injections should be alternated between the left and right buttock.

How much is given

The recommended initial dose of Signifor LAR is 40 mg administered by deep intramuscular injection every 4 weeks.

If you have or had liver problems in the past your doctor may want to start your treatment with a lower initial dose of 20 mg of Signifor LAR every 4 weeks.

Depending on how you respond to the treatment with Signifor LAR your doctor may prescribe a higher or lower dose.

How long you will need to take this medicine

Continue taking Signifor LAR every 4 weeks for as long as your doctor tells you.

This is a long-term treatment, possibly lasting for years. Your doctor will regularly monitor your condition to check that the treatment is having the desired effect. If you interrupt your treatment with Signifor LAR, your growth hormone (GH and IGF-1) levels may increase again and your symptoms may come back.

If you have questions about how long to take Signifor LAR, talk to your doctor or your pharmacist.

If you forget to have your injection

If you forget to have your injection, have it as soon as you remember and then go back to your normal schedule. It will not do any harm if your dose is a few days late but some of your symptoms may come back temporarily until you get back on schedule.

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Signifor LAR. Do this even if there are no signs of discomfort or poisoning. Keep the telephone numbers for these places handy.
