1. WHAT METOJECT 50 MG/ML IS AND WHAT IT IS USED FOR
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 Metoject 50 mg/ml.
Driving and using machines
Treatment with Metoject 50 mg/ml 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.
Metoject 50 mg/ml contains sodium
This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially “sodiumfree”.
3. HOW TO USE METOJECT 50 MG/ML
Your doctor decides on the dosage, which is adjusted individually. Usually it takes 4 – 8 weeks before
there is any effect of the treatment.
Metoject 50 mg/ml 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. Metoject 50 mg/ml may be injected intramuscularly (in a muscle),
intravenously (in a vein) or subcutaneously (under the skin).
Metoject contains methotrexate as active substance.
As there is very little data about giving the medicine intravenously in children and adolescents, it must
only be injected under the skin or into a muscle.
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
The doctor decides on the appropriate dose in children and adolescents with polyarthritic forms of
juvenile idiopathic arthritis. Metoject is not recommended in children less than 3 years of age due to
insufficient experience in this age group.
Metoject 50 mg/ml 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 psoriatic 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,
Metoject 50 mg/ml 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.

Warnings and precautions
Talk to your doctor or pharmacist before taking Metoject 50 mg/ml 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 Metoject 50 mg/ml 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 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.
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
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 Metoject 50 mg/ml you must not be vaccinated with live
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 Metoject 50 mg/ml 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.

miscarriage. Men and women should use an effective method of birth control during treatment and for a
further six months after treatment with Metoject 50 mg/ml has been discontinued.
Method and duration of administration
Metoject 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 Metoject is a
long term treatment.
At the start of your therapy, Metoject may be injected by medical staff. In certain cases your doctor may
decide to instruct you how to inject Metoject under the skin yourself. You will then receive appropriate
training. Under no circumstances should you try to inject Metoject 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

contamination, the affected area must be rinsed immediately with plenty of water.
If you have the impression that the effect of Metoject 50 mg/ml 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:
