1. What is Octreotide GP-Pharm and what is it used for

Octreotide GP-Pharm contains octreotide. This medicine 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 this medicine over somatostatin are that it is more potent and its effects are longer-lasting.

Octreotide GP-Pharm 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. This medicine significantly reduces the symptoms of acromegaly, which include headache, excessive sweating, numbness of the hands and feet, fatigue, and joint pain.
• to alleviate 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 this medicine helps control these symptoms.
• to prevent complications after pancreatic surgery. Treatment with this medicine helps reduce the likelihood 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 this medicine 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.

This medicine 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 Octreotide GP-Pharm

Do not use Octreotide GP-Pharm:

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

Warnings and precautions

Consult your doctor before starting treatment with Octreotide GP-Pharm:

• if you currently have or have had gallstones in the past or have any complications such as fever, chills, abdominal pain, or yellowing of the skin or eyes; inform your doctor, as prolonged use of Octreotide GP-Pharm 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 using Octreotide GP-Pharm 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 Octreotide GP-Pharm 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 Octreotide GP-Pharm in children.

Using Octreotide GP-Pharm with other medicines:

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 Octreotide GP-Pharm. However, it has been reported that some medicines such as cimetidine, cyclosporine, bromocriptine, quinidine, and terfenadine are affected by Octreotide GP-Pharm.

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 adapt treatment with Octreotide GP-Pharm.

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.

Octreotide GP-Pharm should only be used during pregnancy if it is strictly necessary.

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

You should not breastfeed during treatment with Octreotide GP-Pharm. It is not known whether Octreotide GP-Pharm passes into breast milk.

Driving and using machines

Octreotide GP-Pharm 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 Octreotide GP-Pharm, such as headache and fatigue, may reduce your ability to drive and use machines safely.

3. How to use Octreotide GP-Pharm

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, this medicine is administered by:

• subcutaneous injection (under the skin) or
• intravenous infusion (into 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 this medicine 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. It can be warmed in the hand, but not heated.

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 afterward.

Before using a vial of Octreotide GP-Pharm, check for the presence of particles or a change in color. Do not use it if you notice anything abnormal.

If you use more Octreotide GP-Pharm than you should:

Symptoms of overdose are: irregular heartbeat, low blood pressure, cardiac arrest, decreased 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, swelling, and 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. You can also call the Toxicology Information Service, phone 91.562.04.20, indicating the medicine and the amount used.

If you forget to use Octreotide GP-Pharm

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

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

If you stop treatment with Octreotide GP-Pharm

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

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

Treatment is normally initiated 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.

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

• Gastroesophageal Variceal Bleeding

The recommended dose is 25 micrograms/hour for 5 days by continuous intravenous infusion. Blood sugar level control is necessary during treatment.
