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

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.
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.

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