Octreotide is used:

• in acromegaly, a condition where the body produces too much growth hormone. Normally, growth hormone controls growth of tissues, organs, and bones. Too much growth hormone leads to an increase in the size of bones and tissues, especially in the hands and feet. Octreotide markedly reduces the symptoms of acromegaly, which include headache, excessive perspiration, numbness of the hands and feet, tiredness, and joint pain.
• to relieve symptoms associated with some tumours of the gastrointestinal tract (e.g. carcinoid tumours, VIPomas, glucagonomas, gastrinomas, insulinomas). In these conditions, there is overproduction of some specific hormones and other related substances by the stomach, bowels, or pancreas. This overproduction upsets the natural hormonal balance of the body and results in a variety of symptoms, such as flushing, diarrhoea, low blood pressure, rash, and weight loss. Treatment with Octreotide helps to control these symptoms.
• to prevent complications following surgery of the pancreas gland. Treatment with Octreotide helps to lower the risk of complications (e.g. abscess in the abdomen, inflammation of the pancreas gland) after the surgery.
• to stop bleeding and to protect from re-bleeding from ruptured gastro-oesophageal varices in patients suffering from cirrhosis (chronic liver disease). Treatment with Octreotide helps to control bleeding and reduce transfusion requirements.
• to treat pituitary tumours that produce too much thyroid-stimulating hormone (TSH). Too much thyroid-stimulating hormone (TSH) leads to hyperthyroidism.
  Octreotide is used to treat people with pituitary tumours that produce too much thyroid-stimulating hormone (TSH):
• when other types of treatment (surgery or radiotherapy) are not suitable or have not worked;
• after radiotherapy, to cover the interim period until the radiotherapy becomes fully effective.

Do not use Octreotide:

• if you are allergic to octreotide or any of the other ingredients of this medicine (listed in section 6).

Subcutaneous injection

The upper arms, thighs, and abdomen are good areas for subcutaneous injection.

Choose a new site for each subcutaneous injection so that you do not irritate a particular area. Patients who will be injecting themselves must receive precise instructions from the doctor or nurse.

If you store the medicine in the refrigerator, it is recommended that you allow it to reach room temperature before using it. This will reduce the risk of pain at the site of injection. You can warm it up in your hand but do not heat it.

A few people experience pain at the site of the subcutaneous injection. This pain usually only lasts a short time. If this happens to you, you can relieve this by gently rubbing the site of injection for a few seconds afterwards.

Before using a Octreotide ampoule, check the solution for particles or a change of colour. Do not use it if you see anything unusual.
