1. What Sandostatin is and what it is used for

Sandostatin is a synthetic compound derived from somatostatin, a substance that is normally found in the human body, which inhibits the effects of some hormones such as growth hormone. The advantages of Sandostatin over somatostatin are that it is more potent and its effects are longer-lasting.

Sandostatin is used

• for acromegaly, a disease in which the body produces too much growth hormone. Normally, growth hormone controls the growth of tissues, organs, and bones. An excess of growth hormone means an increase in the size of bones and tissues, especially in the hands and feet. Sandostatin significantly reduces the symptoms of acromegaly, which include headache, excessive sweating, numbness of the hands and feet, fatigue, and joint pain.
• to relieve symptoms associated with some gastrointestinal tumors(e.g., carcinoid tumors, VIPomas, glucagonomas, gastrinomas, insulinomas, GRFomas). In these diseases, there is an overproduction of specific hormones and other related substances by the stomach, intestine, or pancreas. This overproduction disrupts the body's natural hormonal balance and produces various symptoms, such as hot flashes, diarrhea, low blood pressure, hives, and weight loss. Treatment with Sandostatin helps control these symptoms.
• to prevent complications after pancreatic surgery. Treatment with Sandostatin helps reduce the possibility of complications after surgery (e.g., abdominal abscesses, pancreatitis).
• to stop bleeding and protect against repeated bleeding from gastroesophageal varicesin patients with cirrhosis (chronic liver disease). Treatment with Sandostatin helps control bleeding and reduce the need for transfusions.
• to treat pituitary tumors that produce too much thyroid-stimulating hormone (TSH). An excess of thyroid-stimulating hormone (TSH) causes hyperthyroidism.

Sandostatin is used to treat people with pituitary tumors 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 period until the radiotherapy is fully effective.

2. What you need to know before you use Sandostatin

Do not use Sandostatin:

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

Warnings and precautions

Talk to your doctor before starting treatment with Sandostatin:

• if you currently have gallstones or have had them in the past, or if you have any complications such as fever, chills, abdominal pain, or yellowing of the skin or eyes; inform your doctor, as prolonged use of Sandostatin may cause gallstones to form. Your doctor may want to check your gallbladder periodically.

• if you have problems with blood sugar levels, either too high (diabetes) or too low (hypoglycemia). When Sandostatin is used to treat bleeding from gastroesophageal varices, it is mandatory to monitor blood sugar levels.

• if you have a history of vitamin B12 deficiency, your doctor may monitor your B12 levels periodically.

• octreotide may reduce heart rate and at very high doses may cause an abnormal heart rhythm. Your doctor may monitor your heart rate during treatment.

Tests and checks

If you receive treatment with Sandostatin for a prolonged period, your doctor may periodically check your thyroid function.

Your doctor will check your liver function.

Your doctor may check the functioning of your pancreatic enzymes.

Children

There is limited experience with the use of Sandostatin in children.

Other medicines and Sandostatin

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Normally, you can continue taking other medicines while being treated with Sandostatin. However, it has been reported that some medicines such as cimetidine, ciclosporin, bromocriptine, quinidine, and terfenadine are affected by Sandostatin.

If you are taking a medicine to control blood pressure (e.g., a beta-blocker or a calcium channel blocker) or an agent to control fluid and electrolyte balance, your doctor may need to adjust the dose.

If you are diabetic, your doctor may need to adjust your insulin dose.

If you are going to receive treatment with lutetium (177Lu) oxodotreotide, a radiopharmaceutical, your doctor may interrupt and/or adjust treatment with Sandostatin.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

Sandostatin should only be used during pregnancy if it is strictly necessary.

Women of childbearing age must use an effective contraceptive method during treatment.

Do not breastfeed during treatment with Sandostatin. It is unknown whether Sandostatin passes into breast milk.

Driving and using machines

Sandostatin has no or negligible influence on the ability to drive and use machines. However, some of these side effects that you may experience during treatment with Sandostatin, such as headache and fatigue, may reduce your ability to drive and use machines safely.

Sandostatin contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per ampoule; this is essentially "sodium-free".

3. How to use Sandostatin

Follow the instructions for administration of this medicine exactly as indicated by your doctor or pharmacist. If you are unsure, consult your doctor or pharmacist again.

Depending on the disease being treated, Sandostatin is administered by:

• subcutaneous injection (under the skin) or
• intravenous infusion (in a vein).

If you have liver cirrhosis (chronic liver disease), your doctor may need to adjust your maintenance dose.

Your doctor or nurse will explain how to inject Sandostatin under the skin, but infusion into a vein must always be performed by a healthcare professional.

• Subcutaneous injection

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

A new site should be chosen for each subcutaneous injection to avoid irritating a specific area. Patients who are going to administer the injection themselves should receive specific instructions from their doctor or nurse.

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

A few patients experience pain at the subcutaneous injection site. This pain usually only lasts for a short period. If this happens to you, you can alleviate it by gently massaging the injection site for a few seconds afterwards.

Before using a Sandostatin ampoule, check for the presence of particles or a change in color. Do not use it if you notice anything abnormal.

If you use more Sandostatin than you should

The symptoms of overdose are: irregular heartbeat, low blood pressure, cardiac arrest, reduced oxygen supply to the brain, severe pain in the upper abdomen, yellowing of the skin and eyes, nausea, loss of appetite, diarrhea, weakness, fatigue, lack of energy, weight loss, abdominal swelling, abdominal discomfort, high levels of lactic acid in the blood, and abnormal heart rhythm.

If you think you have overdosed and experience any of these symptoms, inform your doctor immediately.

In case of overdose or accidental ingestion, you can also contact the Toxicology Information Service, Tel. 91 5620420.

If you forget to use Sandostatin

Administer a dose as soon as you remember and then continue with your usual schedule. It will not harm you if you forget a dose, but your symptoms may temporarily recur until you return to your usual treatment schedule.

Do not inject a double dose to make up for missed individual doses.

If you stop treatment with Sandostatin

If you stop your treatment with Sandostatin, your symptoms may recur. Therefore, do not stop treatment with Sandostatin unless your doctor tells you to.

If you have any further questions about the use of this medicine, ask your doctor, nurse, or pharmacist.

Other sources of information

Detailed and updated information on this medicinal product is available on the website of the Spanish Agency for Medicines and Health Products (AEMPS) http://www.aemps.gob.es/

This information is intended only for healthcare professionals:

• Intravenous infusion (for healthcare professionals)

Visually check if the medicinal product shows a change in color or visible particles before administration. Do not use it if you observe anything abnormal. For intravenous infusion, dilute the medicinal product before administration.

Sandostatin (octreotide acetate) is physically and chemically stable for 24 hours in sterile physiological saline solution or sterile 5% glucose (dextrose) solutions in water. However, since Sandostatin may affect glucose homeostasis, it is recommended to use physiological saline solutions instead of dextrose.

The diluted solutions are physically and chemically stable for at least 24 hours below 25°C. From a microbiological point of view, the diluted solution should be used immediately. If not used immediately, the storage time and conditions before use are the responsibility of the user.

The contents of a 500 microgram ampoule are normally dissolved in 60 ml of saline solution, and the resulting solution is administered through an infusion pump. This should be repeated as necessary until the prescribed treatment duration is reached.

How much Sandostatin to use

The dose of Sandostatin depends on the disease being treated.

• Acromegaly

Treatment is usually started at a dose of 0.05 to 0.1 mg every 8 or 12 hours by subcutaneous injection. It is then changed according to its effects and symptom relief (such as fatigue, sweating, and headache). In most patients, the optimal daily dose will be 0.1 mg 3 times/day. The maximum dose should not exceed 1.5 mg/day.

• Gastrointestinal tract tumors

Treatment is usually started at a dose of 0.05 mg once or twice a day by subcutaneous injection. Depending on the response and tolerability, the dose can be gradually increased to 0.1 mg to 0.2 mg 3 times/day. In carcinoid tumors, treatment should be discontinued if no improvement is observed after 1 week of treatment at the maximum tolerated dose.

• Complications after pancreatic surgery

The usual dose is 0.1 mg 3 times/day by subcutaneous injection for 1 week, starting at least 1 hour before surgery.

• Gastroesophageal variceal hemorrhage

The recommended dose is 25 micrograms/hour for 5 days by continuous intravenous infusion. Blood sugar levels should be monitored during treatment.

• Pituitary adenomas secreting TSH

The effective dose is usually 100 micrograms three times a day by subcutaneous injection. The dose can be adjusted according to the TSH and thyroid hormone response. At least 5 days are needed to assess efficacy.
