1. What is IMULDOSA and what is it used for

What is IMULDOSA

IMULDOSA contains the active substance “ustekinumab”, a monoclonal antibody. Monoclonal antibodies are proteins that identify and bind specifically to certain proteins in the body.

IMULDOSA belongs to a group of medicines called “immunosuppressants”. These medicines work by weakening part of the immune system.

What is IMULDOSA used for

IMULDOSA is used to treat the following inflammatory diseases:

  • Plaque psoriasis - in adults and children aged 6 years and older
  • Psoriatic arthritis - in adults
  • Moderate to severe Crohn's disease - in adults

Plaque psoriasis

Plaque psoriasis is a skin disease that causes inflammation affecting the skin and nails. IMULDOSA reduces inflammation and other signs of the disease.

IMULDOSA is used in adults with moderate to severe plaque psoriasis who cannot use ciclosporin, methotrexate, or phototherapy, or where these treatments do not work.

IMULDOSA is used in children and adolescents aged 6 years and older with moderate to severe plaque psoriasis who are not able to tolerate phototherapy or other systemic therapies or where these treatments do not work.

Psoriatic arthritis

Psoriatic arthritis is an inflammatory disease of the joints, which is usually accompanied by psoriasis. If you have active psoriatic arthritis, you will first receive other medicines. If you do not respond well to these medicines, you may be treated with IMULDOSA to:

  • Reduce the signs and symptoms of your disease.
  • Improve your physical function.
  • Reduce damage to your joints.

Crohn's disease

Crohn's disease is an inflammatory disease of the intestine. If you have Crohn's disease, you will first be given other medicines. If you do not respond adequately or do not tolerate these medicines, you may be given IMULDOSA to reduce the signs and symptoms of your disease.

2. What you need to know before you use IMULDOSA

Do not use IMULDOSA

  • If you are allergic to ustekinumabor any of the other ingredients of this medicine (listed in section 6).
  • If you have an active infectionthat your doctor thinks is important.

If you are not sure if anyof the above applies to you, talk to your doctor or pharmacist before using IMULDOSA.

Warnings and precautions

Talk to your doctor or pharmacist before starting IMULDOSA. Your doctor will check how you are before each treatment. Make sure you tell your doctor about any illness you have before each treatment. Your doctor will also ask if you have recently been near someone who may have tuberculosis. Your doctor will examine you and do a test to detect tuberculosis before you use IMULDOSA. If your doctor thinks you are at risk of tuberculosis, you may be given medicines to treat it.

Look out for serious side effects

IMULDOSA may cause serious side effects, including allergic reactions and infections. You should be aware of certain signs of illness while you are using IMULDOSA. See the complete list of these side effects in “Serious side effects” in section 4.

Tell your doctor before using IMULDOSA:

  • If you have ever had an allergic reaction to IMULDOSA.Check with your doctor if you are not sure.
  • If you have ever had any type of cancer– this is because immunosuppressants like IMULDOSA weaken part of the immune system. This may increase the risk of having cancer.
  • If you have received treatment for psoriasis with other biologics (a medicine produced from a biological source and usually given by injection)– the risk of having cancer may be higher.
  • If you have had a recent infection.
  • If you have any new or changing lesionswithin the area of psoriasis or on intact skin.
  • If you are taking any other treatment for psoriasis and/or psoriatic arthritis– such as any other immunosuppressant or phototherapy (when your body is treated with a type of ultraviolet light (UV)). These treatments may also weaken part of the immune system. It has not been studied whether these treatments can be used together with IMULDOSA. However, it may increase the likelihood of suffering from diseases related to a weaker immune system.
  • If you are receiving or have ever received allergy shots– it is not known if IMULDOSA can affect these treatments.
  • If you are 65 years of age or older– you are more likely to get infections.

If you are not sure if you have any of these conditions, talk to your doctor or pharmacist before using IMULDOSA.

Some patients have experienced lupus-like reactions during treatment with ustekinumab, including cutaneous lupus or lupus-like syndrome. Talk to your doctor immediately if you experience a red, raised, and scaly skin rash, sometimes with a darker border, in areas of skin exposed to the sun or if accompanied by joint pain.

Heart attacks and strokes

In a study in patients with psoriasis treated with ustekinumab, heart attacks and strokes have been observed. Your doctor will periodically check your risk factors for heart disease and stroke to ensure they are being treated properly. Seek medical attention immediately if you experience chest pain, weakness, or unusual sensation on one side of the body, facial paralysis, or abnormalities in speech or vision.

Children and adolescents

IMULDOSA is not recommended for use in children under 6 years of age with psoriasis or in children under 18 years of age with psoriatic arthritis, Crohn's disease, or ulcerative colitis, as it has not been studied in this age group.

Using IMULDOSA with other medicines, vaccines

Tell your doctor or pharmacist:

  • If you are using, have recently used, or might use other medicines.
  • If you have been vaccinated recently or are going to have a vaccination.Certain types of vaccines (live vaccines) must not be given while you are using IMULDOSA.
  • If you received IMULDOSA during pregnancy, inform your baby's doctor about your treatment with IMULDOSA before your baby receives any vaccination, including live vaccines such as the BCG vaccine (used to prevent tuberculosis).Live vaccines are not recommended for your baby in the first 12 months after birth if you received IMULDOSA during pregnancy, unless your baby's doctor recommends otherwise.

Pregnancy and breastfeeding

  • If you are pregnant or think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
  • No increased risk of birth defects has been observed in babies exposed to Imuldosa in the womb.However, there is limited experience with Imuldosa in pregnant women. Therefore, it is preferable to avoid the use of Imuldosa during pregnancy.
  • If you are a woman of childbearing age, you are advised to avoid becoming pregnant and to use adequate contraceptive measures while using Imuldosa and for at least 15 weeks after the last treatment with Imuldosa.Imuldosa may pass through the placenta to the fetus. If you received Imuldosa during pregnancy, your baby may have a higher risk of getting an infection.
  • It is important that you inform your baby's doctors and other healthcare professionals if you received Imuldosa during your pregnancy before your baby receives any vaccination.Live vaccines, such as the BCG vaccine (used to prevent tuberculosis), are not recommended for your baby in the first 12 months after birth if you received Imuldosa during pregnancy, unless your baby's doctor recommends otherwise.
  • Ustekinumab may be excreted in breast milk in very small amounts.If you are breastfeeding or plan to breastfeed, talk to your doctor. You and your doctor will decide whether you should breastfeed or use Imuldosa. Do not do both.

Preparation to use the pre-filled syringe

  • Remove the pre-filled syringe(s) from the refrigerator. Let the pre-filled syringe sit outside the carton for 30 minutes. This will allow the liquid to reach a comfortable temperature for injection (room temperature). Do not remove the needle cap while waiting for the syringe to reach room temperature.
  • Hold the pre-filled syringe by the body with the needle cap pointing upwards.
  • Do not hold the pre-filled syringe by the plunger, plunger head, needle protector wings, or needle cap.
  • Do not remove the plunger at any time.
  • Do not remove the pre-filled syringe cap until instructed to do so.
  • Do not touch the activation clips on the needle protector to avoid covering the needle prematurely.

Check the pre-filled syringe(s) to ensure that

  • the number of pre-filled syringes and concentration are correct
  • If your dose is 45 mg, you will have one 45 mg IMULDOSA pre-filled syringe.
  • If your dose is 90 mg, you will have two 45 mg IMULDOSA pre-filled syringes and you will need to administer two injections. Choose two different sites for these injections (e.g., one in the right thigh and one in the left thigh), and inject one after the other.
  • it is the correct medicine.
  • the expiry date has not passed.
  • the pre-filled syringe is not damaged.
  • the solution in the pre-filled syringe is clear to slightly opalescent and colorless to slightly yellowish.
