1. What Injexate is and what it is used for


Injexate contains methotrexate as active substance


Methotrexate is a substance with following properties:


Injexateis indicated for the treatment of



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.


Injexate 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 Injexate


Do not use Injexate if you:


Warnings and precautions

Talk to your doctor or pharmacist or nurse before taking Injexate if:


Recommended follow‑up examinations and safety measures:

Even when Injexate 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:



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 Injexate 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 Injexate 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 disease.


Other medicines and Injexate

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 Injexate is administered at the same time as certain other drugs:



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.


Injexate 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 Injexate.


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 Injexate 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 during a further six months after treatment with Injexate 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 has to be stopped prior to and during treatment with Injexate.


Driving and using machines

Treatment with Injexate 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.

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


3. How to use Injexate


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


Injexate is administered subcutaneously (under the skin) 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.


Use in children and adolescents

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


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

Method and duration of administration

Injexate 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 Injexate is a long-term treatment.


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


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