1. What Myrelez is and what it is used for
Myrelez contains the active substance lanreotide, which belongs to a group of medicines called somatostatin analogues. It is similar to another substance (hormone) called somatostatin. Lanreotide reduces the activity of certain hormones such as growth hormone (GH) and insulin-like growth factor (IGF-1) and inhibits the release of certain gastrointestinal hormones and intestinal secretions. It also has an effect on certain advanced types of tumors (called neuroendocrine tumors) in the gut and pancreas, by inhibiting or slowing their growth.
What Myrelez is used for:
- treatment of acromegaly (a condition where the body produces too much growth hormone);
- relief of symptoms such as hot flashes and diarrhea that sometimes occur in patients with neuroendocrine tumors (NETs);
- treatment and inhibition of growth of certain advanced tumors in the gut and pancreas, called gastroenteropancreatic neuroendocrine tumors (GEP-NETs) - when they cannot be removed by surgery.
2. What you need to know before you use Myrelez
When not to use Myrelez:
- if you are allergic (hypersensitive) to lanreotide, somatostatin, or other medicines of the same group (somatostatin analogues), or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before starting treatment with Myrelez, discuss with your doctor, pharmacist, or nurse:
- if you have diabetes, as lanreotide can cause fluctuations in blood sugar levels. During treatment with Myrelez, your doctor may recommend checking your blood sugar levels and possibly changing your diabetes treatment plan;
- if you have been diagnosed with gallstones, as Myrelez can promote the formation of gallstones. In this case, periodic examination is recommended. If complications of gallstones occur, your doctor may decide to stop treatment with lanreotide.
- if you have any thyroid function disorders, as lanreotide may slightly disrupt thyroid function;
- if you have heart function disorders, as Myrelez may cause bradycardia (slow heart rate). Caution should be exercised when starting treatment with Myrelez in patients with bradycardia.
If you have any of the above conditions, discuss them with your doctor or pharmacist before starting treatment with Myrelez.
Children
Myrelez is not recommended for use in children.
Myrelez and other medicines
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or might take. Be cautious when using the following medicines:
- cyclosporine(a medicine that lowers the immune system response and is used, for example, after transplantation or in autoimmune diseases);
- bromocriptine(a dopamine receptor agonist used to treat pituitary tumors, Parkinson's disease, or to inhibit lactation);
- medicines that cause bradycardia(medicines that slow down heart rate, such as beta-blockers).
Your doctor may consider modifying the dosage of these medicines.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. In these cases, Myrelez will only be used if necessary.
Driving and using machines

INSTRUCTIONS FOR USE
A. Contents of the box
Below is a description of how to perform the injection of Myrelez. Read the instructions carefully before performing the injection.

The contents of the pre-filled syringe are a semi-solid phase with a gel-like appearance, sticky properties, and a color ranging from white to light yellow. The saturated solution may also contain microbubbles, which may disappear during injection. These differences are normal and do not affect the quality of the product.
B. Before starting
B1. Remove Myrelez from the refrigerator 30 minutes before performing the injection. The laminated bag should be opened just before injection.
B2. Before opening the bag, check the integrity of the packaging and the expiration date of the medicine. The expiration date is printed on the bag and the box. – Do not use the medicine after the expiration date or if the bag is damaged.
B3. Before starting, wash your hands thoroughly with soap and dry them.
B4. Make sure the surface for preparing the injection is clean.
B5. Choose the injection site – the sites are shown below.
B6. Remember to clean the injection site.
B7. Tear open the bag and remove the pre-filled syringe.


When injecting another person: inject into the upper outer quadrant of the buttock.

When self-injecting: inject into the upper outer part of the thigh. The injection site should be changed with each administration, alternating between the left and right sides.
C. Preparing the syringe

C1: Remove the syringe cap
Hold the syringe body firmly with one hand (not the plunger). With the other hand, remove the cap by twisting it.
C2: Open the needle packaging
Hold the needle packaging and pull off the cover. Note: Do not touch the open end of the needle packaging. It must remain clean.
C3: Insert the syringe into the open end of the needle packaging
Hold the needle packaging with one hand. With the other hand, hold the syringe body firmly (not the plunger) and twist until the syringe and needle are fully locked.


The syringe and needle are fully locked when they can no longer be twisted.
Important: Make sure to tighten the syringe securely to avoid leakage of the medicine.
C4: Remove the needle from the packaging
Hold the syringe body (not the plunger). Remove the needle straight from the packaging without twisting or turning it, to ensure the syringe is properly connected to the safety needle. Note: From this stage, the needle is partially exposed. Never touch or try to open the green needle shield. The green needle shield is not a removable cap or case for the needle. The green needle shield is activated automatically during injection (when the needle is inserted). The green needle shield will automatically cover the needle and lock around it after the injection is complete. The green needle shield is a self-acting safety mechanism.
D. Performing the injection


D1: Position the syringe
The injection sites are shown in section B. Stretch the skin around the injection site with your thumb and index finger, so it is flat. With your other hand, hold the lower part of the syringe body (not the plunger). Position the syringe at a 90° angle to the skin.

D2: Insert the needle
Without creating a skin fold or squeezing the skin at the injection site, firmly press the needle into the skin. The green needle shield will retract and the safety mechanism will be activated.
Continue until only the green needle shield collaris visible.
Do notpush the plunger at this stage. Hold the syringe in this position for the next step.

D3: Press the plunger
Move your hand from the skin to the plunger. Slowlypress the plunger until its top reaches the syringe body (it is easier to push the plunger with your dominant hand). This should take about 20 seconds.
E. Remove and dispose of the syringe

E1: Remove from the skin
Lift the syringe upwards and away from the patient's body. The green needle shield will cover the needle.

E2: Gently press
Gently press the injection site with a dry swab or sterile gauze to prevent bleeding. After administering the medicine, do notrub or massage the injection site.


E3: Dispose of
Dispose of the used syringe and needle according to local regulations or your doctor's instructions. Needles are not reusable. Do notthrow the syringe or needle into household waste.
Using more Myrelez than prescribed
If you have injected more Myrelez than prescribed, tell your doctor. If you have injected more Myrelez than prescribed, there is a risk of additional or more severe side effects (see section 4. Possible side effects).
Missing a dose of Myrelez
If you realize you have missed an injection, contact your doctor, who will inform you about the next injection schedule. Do not administer additional injections to make up for the missed dose without consulting your doctor.
Stopping treatment with Myrelez
Missing more than one dose or stopping treatment with Myrelez early may affect the effectiveness of the therapy. Consult your doctor before stopping treatment with Myrelez. If you have any further questions on the use of this product, ask your doctor or pharmacist.
