1. What Oczyesa is and what it is used for

Oczyesa contains the active substance octreotide. Octreotide belongs to the pharmaco-therapeutic group pituitary and hypothalamic hormones and analogues, somatostatin and analogues. Octreotide is a synthetic form of somatostatin, a natural substance found in the human body that controls the release of human growth hormone. Octreotide works in the same way as somatostatin, but its action lasts longer so it does not need to be taken so often.

Oczyesa is used for maintenance treatment in adults with acromegaly, a condition wherein the body produces too much growth hormone. It is used in patients in whom medicines like somatostatin have already been shown to be of benefit.

Normally, growth hormone regulates the growth of tissues, organs and bones. In people with acromegaly, increased production of growth hormone (usually from a non-cancerous tumour in the pituitary gland) leads to enlargement of bones and certain tissues, and symptoms such as headache, excessive sweating, numbness in the hands and feet, tiredness and joint pain. Treatment with Oczyesa can help relieve the symptoms.

2. What you need to know before you use Oczyesa
Do not use Oczyesa
  • if you are allergic to octreotide or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before using Oczyesa or during treatment if you have:

  • heart problems since the medicine can affect the rate and regularity of your heartbeat.
  • gallbladder problems, since prolonged use of Oczyesa can cause gallstones to form.
  • diabetes, since Oczyesa may affect your blood sugar. Persistently increased blood sugar levels may occur during long-term use. Low blood sugar levels have also been reported. Therefore, your doctor may recommend monitoring your blood sugar levels and treatment of diabetes.
    If you have Type 1 diabetes and you are being treated with insulin, your doses may need to be reduced during treatment with Oczyesa.
  • ever had lack of vitamin B12. Since this medicine can decrease vitamin B12 levels in the blood, your doctor may wish to check your vitamin B12 level periodically during treatment with Oczyesa.

Monitoring during treatment

Tumours of the pituitary gland that produce excess growth hormone and lead to acromegaly sometimes expand, causing serious complications such as visual problems. It is essential that you are monitored for tumour growth while taking Oczyesa. If evidence of tumour expansion appears, your doctor may prescribe a different treatment.

Your doctor will regularly check your liver function during treatment and will also check your thyroid function if you are treated with Oczyesa over a long period of time.

Children and adolescents

Oczyesa is not recommended in children and adolescents below the age of 18. The safety and benefits of this medicine are not known in this age group.

Other medicines and Oczyesa

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

Tell your doctor if you are taking any of the following medicines, since their activity or side effects may change when used together with Oczyesa. If you take these medicines, your doctor may need to adjust the doses of these medicines:

  • medicines called beta blockers (e.g. atenolol, metoprolol) and calcium channel blockers (e.g. amlodipine, verapamil), used to treat high blood pressure or heart diseases;
  • medicines to control your fluid and electrolyte balance;
  • insulin or other medicines to treat diabetes;
  • quinidine: a medicine to treat irregular heart rhythm;
  • terfenadine: a medicine to treat allergic conditions;
  • ciclosporin: a medicine to suppress transplant rejection, treat severe skin diseases, severe eye and joint inflammation.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are pregnant, the use of Oczyesa should be avoided.

It is not known whether Oczyesa passes into breast milk. Do not breast-feed while using Oczyesa.

Women who can get pregnant should use effective contraception during treatment.

Driving and using machines

Oczyesa has no or negligible influence on the ability to drive and use machines. Avoid driving or using machines if your ability to react is reduced due to side effects such as dizziness, asthenia or headache.

Oczyesa contains alcohol

This medicine contains 63 mg of alcohol (ethanol) in each dose unit which is equivalent to 63 mg/1 mL (6.5% w/w). The amount in 1 dose of this medicine is equivalent to less than 2 mL beer or 1 mL wine. The small amount of alcohol in this medicine will not have any noticeable effects.

3. How to use Oczyesa

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is 20 mg every 4 weeks. Oczyesa may be given up to 1 week before or 1 week after the scheduled 4-week dose in exceptional circumstances (e.g., missed dose, non-adherence to treatment, etc.).

If you are switching from another treatment with octreotide or lanreotide, the first dose of Oczyesa should be given at the end of the daily or monthly dosing interval of the previous treatment.

Your doctor will assess how the treatment works for you in terms of IGF-I and symptom control on a regular basis. Should control not be maintained or the medicine not be tolerated, you may be switched to another somatostatin analogue.

Oczyesa is given as a single injection under the skin (subcutaneously (SC)) of the belly, thigh or buttock. The injection should not be given in any other area. When receiving monthly injections, it is important to change the site where the injection is given each time. You may receive multiple injections in the same area, but each injection must be given in a different spot.

You should receive training on the right way to inject Oczyesa. Read the ‘Instructions for use’ for the pre-filled pen carefully before using Oczyesa.

Detailed instructions on how to use Oczyesa are provided at the end of this leaflet.

If you forget to use Oczyesa

Do not take a double dose to make up for a forgotten dose. Administer the next dose as soon as you remember.

  • Do not use this medicine if you notice visible particles or if it is cloudy.

Step 3. Wash your hands

  • Wash your hands well with soap and water. Dry your hands completely.

Step 4. Choose the injection site

  • Choose an injection area (belly, thigh, or buttock). Choose an injection site in the injection area where there is enough fatty (subcutaneous) tissue. Each injection area can have multiple injection sites.
  • You may need help from someone who has been instructed in how to give your injection if you cannot reach certain injection areas.
  • Do not inject into skin that is tender, damaged, bruised or scarred.
  • Do not inject in a recently used injection site in the chosen injection area.
  • Do not inject within 5 cm of the navel.

Step 5. Clean the injection site

  • Let the injection site air dry before injecting.
  • Do not touch the cleaned area again before the injection.

Step 6. Remove and throw away the protective cap

  • Hold the Oczyesa pre-filled pen pointed up with one hand. With the other hand pull the protective cap straight off. It may take some force to remove. Do not wiggle or twist the cap.
  • Do not recap. Throw away the protective cap right away.
  • You may see a drop of liquid at the end of the needle. This is normal.
  • Do not touch or press the needle guard. This could activate the pre-filled pen.

Injecting Oczyesa

Step 7. Prepare to start the injection

  • Pinch and hold the skin at the injection site between your thumb and fingers. Hold the pinch until the injection is complete.

Step 8. Give the injection

Inject Oczyesa by following the steps in figures A, B and C.

  • You will hear a first click to let you know the injection has started.
  • The plunger rod will move down through the inspection window.
  • Continue to hold the pre-filled pen down.
  • When you hear the second click, continue to keep the pre-filled pen down for an additional 5 seconds.
  • Check that the plunger rod is completely seen in the inspection window.

Step 9. Remove the Oczyesa pre-filled pen

  • Remove the pre-filled pen from the skin. The injection is now completed, and the pinched skin can be released.
  • The needle remains hidden by the needle guard to protect against needle-stick injury.
  • You may have a small amount of blood or liquid at the injection site. This is normal. Use a cotton ball or gauze pad on the area and apply a plaster if needed.
  • Do not rub the injection site.
