1. What Husmetabo is and what it is used for


Husmetabo contains methotrexate as active substance.


Methotrexate is a substance with the following properties:

- it interferes with the growth of certain cells in the body that reproduce quickly

- it reduces the activity of the immune system (the body’s own defence mechanism)

- it has anti-inflammatory effects.


Husmetabo is indicated for the treatment of


- active rheumatoid arthritis in adult patients.

- polyarthritic forms of severe, active juvenile idiopathic arthritis, when the response to nonsteroidal anti-inflammatory drugs (NSAIDs) has been inadequate.

- severe recalcitrant disabling psoriasis, which is not adequately responsive to other forms of therapy such as phototherapy, PUVA, and retinoids, and severe psoriatic arthritis in adult patients.

- mild to moderate Crohn’s Disease in adult patients when adequate treatment with other medicines is not possible.


Rheumatoid arthritis (RA)is a chronic collagen disease, characterised by inflammation of the synovial membranes (joint membranes). These membranes produce a fluid which acts as a lubricant for many joints. The inflammation causes thickening of the membrane and swelling of the joint.


Juvenile arthritis concerns children and adolescents less than 16 years. Polyarthritic forms are indicated if 5 or more joints are affected within the first 6 months of the disease.


Psoriatic arthritis is a kind of arthritis with psoriatric lesions of the skin and nails, especially at the joints of fingers and toes.


Psoriasis is a common chronic skin disease, characterised by red patches covered by thick, dry, silvery, adherent scales.


Husmetabo modifies and slows down the progression of the disease.


Crohn’s Disease is a type of inflammatory bowel disease that may affect any part of the gastrointestinal tract causing symptoms such as abdominal pain, diarrhoea, vomiting or weight loss.


2. What you need to know before you use Husmetabo


Do not use Husmetabo if you:

- are allergic to methotrexate or any of the other ingredients of this medicine (listed in section 6).

- suffer from severe liver or kidney diseases or blood diseases.

- regularly drink large amounts of alcohol.

- suffer from a severe infection, e.g. tuberculosis, HIV or other immunodeficiency syndromes.

- suffer from ulcers in the mouth, stomach ulcer or intestinal ulcer.

- are pregnant or breast‑feeding.

- receive vaccinations with live vaccines at the same time.


Warnings and precautions

Talk to your doctor or pharmacist before using Husmetabo if:

- you are elderly or if you feel generally unwell and weak.

- your liver function is impaired.

- you suffer from dehydration (water loss).


Recommended follow‑up examinations and safety measures

Even when Husmetabo is administered in low doses, severe side effects can occur. In order to detect them in time, check‑ups and laboratory tests have to be carried out by your doctor.


Before therapy

Before starting the treatment, blood samples will be taken in order to check that you have enough blood cells, tests to check your liver function, serum albumin (a protein in the blood) and kidney function. Your doctor will also check if you suffer from tuberculosis (infectious disease in combination with little nodules in the affected tissue) and a chest X‑ray will be taken.


During therapy

You will have the following tests at least once a month during the first six months and at least every three months thereafter:


- Examination of the mouth and throat for alterations of the mucosa

- Blood tests

- Check of liver function

- Check of kidney function

- Check of respiratory system and if necessary lung function test


Methotrexate may affect your immune system and vaccination results. It may also affect the result of immunological tests. Inactive, chronic infections (e.g. herpes zoster [shingles], tuberculosis, hepatitis B or C) may flare up. During therapy with Husmetabo you must not be vaccinated with live vaccines.


Radiation induced dermatitis and sun-burn can reappear under methotrexate therapy (recall-reaction). Psoriatic lesions can exacerbate during UV-irradiation and simultaneous administration of methotrexate.

Enlarged lymph nodes (lymphoma) may occur and therapy must then be stopped.


Diarrhoea can be a toxic effect of Husmetabo and requires an interruption of therapy. If you suffer from diarrhoea please speak to your doctor.


Encephalopathy (a brain disorder) / leukoencephalopathy (a special disorder of the white brain substance) have been reported in cancer patients receiving methotrexate therapy and cannot be excluded for methotrexate therapy in other diseases.


Children

Husmetabo is not recommended in children less than 3 years of age due to insufficient experience in this age group.


Other medicines and Husmetabo

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.


The effect of the treatment may be affected if Husmetabo is administered at the same time as certain other drugs:

- Medicines harming the liver or the blood count, e.g. leflunomide

- Antibiotics (medicines to prevent/fight certain infections) such as: tetracyclines, chloramphenicol, and non-absorbable broad-spectrum antibiotics, penicillines, glycopeptides, sulphonamides (sulphur containing medicines that prevent/fight certain infections), ciprofloxacin and cefalotin

- Non-steroidal anti-inflammatory drugs or salicylates (medicines against pain and/or inflammation)

- Probenecid (medicine against gout)

- Weak organic acids like loop diuretics (“water tablets”) or some medicines used for treatment of pain and inflammatory diseases (e.g. acetylsalicylic acid, diclofenac and ibuprofen) and pyrazole (e.g. metamizol for treating pain)

- Medicinal products, which may have adverse effects on the bone marrow, e.g. trimethoprim-sulphamethoxazole (an antibiotic) and pyrimethamine

- Sulphasalazine (antirheumatic medicine)

- Azathioprine (an immunosuppressive agent sometimes used in severe forms of rheumatoid arthritis)

- Mercaptopurine (a cytostatic agent)

- Retinoids (medicine against psoriasis and other dermatological diseases)

- Theophylline (medicine against bronchial asthma and other lung diseases)

- Proton-pump inhibitors (medicines against stomach trouble)

- Hypoglycaemics (medicines that are used to lower the blood sugar)


Vitamins containing folic acid may impair the effect of your treatment and should only be taken when advised by your doctor.


Vaccination with live vaccine should be avoided.


Husmetabo with food, drink and alcohol

Alcohol as well as large amounts of coffee, caffeine-containing soft drinks and black tea should be avoided during treatment with Husmetabo.


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.


You must not take Husmetabo during pregnancy. There is a risk of harm to the foetus and miscarriage. Men and women should use an effective method of birth control during treatment and for a further six months after treatment with Husmetabo has been discontinued.


In women of child-bearing age, any existing pregnancy must be excluded with certainty by taking appropriate measures, e.g. pregnancy test, prior to therapy.


As methotrexate can be genotoxic, all women who wish to become pregnant are advised to consult a genetic counselling centre, if possible, already prior to therapy, and men should seek advice about the possibility of sperm preservation before starting therapy.


Breast‑feeding should be stopped prior to and during treatment with Husmetabo.


Driving and using machines

Treatment with Husmetabo may cause adverse reactions affecting the central nervous system, e.g. tiredness and dizziness. Thus the ability to drive a vehicle and/or to operate machines may, in certain cases, be compromised. If you feel tired or drowsy you should not drive or use machines.


Husmetabo contains sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially “sodium-free”.


3. How to use Husmetabo


Your doctor decides on the dosage, which is adjusted individually. Usually it takes 4 – 8 weeks before there is any effect of the treatment.


Husmetabo is administered by or under the supervision of a physician or healthcare staff as an injection once a week only. Together with your doctor you decide on a suitable weekday each week on which you receive your injection. Husmetabo should be injected subcutaneously (under the skin).


The doctor decides on the appropriate dose in children and adolescents with polyarthritic forms of juvenile idiopathic arthritis.


Use in children

Husmetabo is not recommended in children less than 3 years of age due to insufficient experience in this age group.

Method and duration of administration

Husmetabo is injected once weekly!

The duration of the treatment is determined by the treating physician. Treatment of rheumatoid arthritis, juvenile idiopathic arthritis, psoriasis vulgaris, psoriatic arthritis and Crohn’s disease with Husmetabo is a long-term treatment.


At the start of your therapy, Husmetabo may be injected by medical staff. In certain cases your doctor may decide to instruct you how to inject Husmetabo under the skin yourself. You will then receive appropriate training.

Under no circumstances should you try to inject Husmetabo yourself before you have received such training.

Please refer to the instructions for use at the end of the leaflet.


The manner of handling and disposal must be consistent with that of other cytostatic preparations in accordance with local requirements. Pregnant health care personnel should not handle and/or administer Husmetabo.


Methotrexate should not come into contact with the surface of the skin or mucosa. In the event of contamination, the affected area must be rinsed immediately with plenty of water.


If you use more Husmetabo than you should

Follow your doctor’s dosage recommendations. Do not change the dosage by yourself.

If you suspect that you have used too much Husmetabo, contact your doctor immediately. He will decide on the adequate treatment depending on the severity of the intoxication.


If you forget to use Husmetabo

Do not take a double dose to make up for a forgotten individual dose. Ask your doctor for advice. Take the dose prescribed by your doctor as soon as possible and each week thereafter.


If you stop using Husmetabo

You should not interrupt or discontinue Husmetabo treatment, unless you have discussed this with your doctor. If you suspect severe side effects, contact your doctor immediately for advice.


If you have the impression that the effect of Husmetabo is too strong or too weak, you should talk to your doctor or pharmacist.


4. Possible side effects


Like all medicines, this medicine can cause side effects, although not everybody gets them.


The frequency as well as the degree of severity of the side effects depends on the dosage level and the frequency of administration. As severe side effects may occur even at low dosage, it is important that you are monitored regularly by your doctor. Your doctor will do tests to check for abnormalities developing in the blood (such as low white blood cells, low platelets, lymphoma) and changes in the kidneys and the liver.


Tell your doctor immediately if you experience any of the following symptoms, as these may indicate a serious, potentially life-threatening side effect, which require urgent specific treatment:
