1. What Ebetrex is and what it is used for
Ebetrex is a drug with the following properties:
- it prevents the growth of certain cells in the body that are reproduced quickly (anti-tumor drugs)
- it reduces unwanted reactions in the body’s defense mechanism (immunosuppressive agent) and
- it has anti-inflammatory effects
Ebetrex is used to treat:
- active rheumatoid arthritis (RA) in adults
- polyarticular forms (when five or more joints are affected) of severe, active juvenile idiopathic arthritis (JIA) when treatment with non-steroidal anti-inflammatory drugs ( NSAIDs ) has not given sufficient results.
- severe therapy-resistant disabling psoriasis, which is not sufficiently improved by other therapies such as light therapy (PUVA) and retinoids, and severe psoriasis affecting the joints (psoriatic arthritis) in adult patients.
Methotrexate contained in Ebetrex may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
2. What you need to know before using Ebetrex
If you have any further questions on the use of Ebetrex, ask your doctor or pharmacist.
Do not use Ebetrex:
- if you are allergic to methotrexate or any of the other ingredients of this medicine (listed in section 6)
- if you have significant kidney disease (the doctor decides how severe the disease is)
- if you have significant liver disease (the doctor decides how severe the disease is)
- if you have any disorders in the blood formation system
- if you consume large amounts of alcohol
- if the function of the body’s own immune system is impaired
- if you have a severe or active infection, e.g. tuberculosis and HIV
- if you have ulcers in the gastrointestinal tract (including ulcers in the oral cavity)
- if you are pregnant or breast-feeding (see section “Pregnancy, breast-feeding and fertility”)

Warnings and cautions
Talk to your doctor or pharmacist before using Ebetrex again
- you have diabetes mellitus which is treated with insulin
- you have an inactive chronic infection (such as tuberculosis, hepatitis B or C, shingles ( herpes zoster))
- you have or have had any liver or kidney disease
- your lung function is impaired
- you have a pathological accumulation of fluid in the abdominal cavity or the space between the lungs and chest wall ( ascites, pleural effusions)
- you are dehydrated or suffer from conditions that lead to dehydration (vomiting, diarrhea, stomatitis ).
Acute hemorrhage from the lungs of patients with the underlying rheumatic disease has been reported with methotrexate. If you experience symptoms such as blood in the saliva or bloody cough, contact your doctor immediately.
The treatment should be given once a week.
Improper intake of methotrexate can lead to serious side effects, including potentially fatal ones.
Read section 3 of this leaflet carefully.
If you have previously had skin problems after radiation therapy (radiation-induced dermatitis ) and burns to the skin after sunbathing, these problems may recur during methotrexate treatment (re-reaction).
Children and young people
Dosage instructions depend on the patient’s body weight. Use is not recommended for children <3 years of age due to a lack of experience in this age group.
Children receiving Ebetrex treatment should be monitored particularly closely by specialist physicians so that any side effects can be identified as early as possible.
Elderly people receiving Ebetrex treatment should be monitored particularly closely by a doctor so that any side effects can be identified as early as possible. Dosage one for elderly patients should be relatively low due to age-related impairment of liver and kidney function and low folate reserves.
Skin changes caused by psoriasis may be exacerbated during treatment with Ebetrex with concomitant UV radiation.
Recommended follow-up examinations and precautions:
Even when Ebetrex is used at low doses, serious side effects can occur. For these to be detected early, the doctor must perform checks and laboratory tests.
Before starting treatment :
Before starting treatment, your doctor will check your blood count, kidney function, and liver function. You may have a chest X-ray. Other tests can also be performed during and after treatment. Be sure to come to agreed blood tests.
If the result of any test is abnormal, treatment will not resume until all results are normal again.
Special precautions for treatment with Ebetrex
Methotrexate temporarily affects sperm and egg production, an effect that in most cases decreases after the end of treatment. Methotrexate can cause miscarriage and severe congenital malformations. You must avoid becoming pregnant while using methotrexate and for at least 6 months after stopping treatment. See also the section “Pregnancy, breast-feeding and fertility”.
Other medicines and Ebetrex
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Remember to tell your doctor that you are being treated with Ebetrex if you are prescribed another medicine while you are being treated. It is especially important to tell your doctor if you are using:
- other treatment for rheumatoid arthritis or psoriasis, such as leflunomide, sulfasalazine (also used for ulcerative colitis ), acetylsalicylic acid, phenylbutazone, or amidopyrine
- alcohol (should be avoided)
- live vaccines
- azathioprine (prevents rejection during organ transplants)
- retinoids (for psoriasis and other skin problems)
- anticonvulsant drugs (for seizures)
- cancer treatment
- barbiturates (sleeping pills)
- birth control pills
- probenecid (for gout )
- pyrimethamine (prevention and treatment of malaria )
- vitamin preparations containing folic acid
- proton pump inhibitor (for severe heartburn and stomach ulcers )
- theophylline (for asthma ).
Ebetrex with food, drink, and alcohol
You should not drink any alcohol during treatment with Ebetrex. Avoid drinking too much coffee, caffeinated cold drinks, or black tea. Make sure you drink plenty of fluids during treatment with Ebetrex as dehydration (reduction of body fluids) may increase the harmful effects of Ebetrex.
Pregnancy, breastfeeding, 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.
Do not use Ebetrex during pregnancy or if you are trying to get pregnant. Methotrexate can cause congenital malformations, birth defects, and miscarriages. It is associated with malformations of the skull, face, heart and blood vessels, brain and arms, and legs. It is therefore very important that methotrexate is not given to pregnant patients or patients planning to become pregnant. Infertile women, pregnancy must be ruled out by appropriate measures, e.g. a pregnancy test before starting treatment.
You must avoid becoming pregnant while taking methotrexate and for at least 6 months after stopping treatment by using reliable contraception during this time (see also the section “Warnings and precautions”).
If you become pregnant during treatment or suspect you may be pregnant, talk to your doctor as soon as possible. You should be offered medical advice on the risk of harmful effects on the child due to the treatment.
If you wish to become pregnant, consult your doctor, who may refer you to specialist advice before the planned start of treatment.
Do not breast-feed during treatment as methotrexate passes into breast milk. If your treating doctor considers methotrexate treatment to be necessary during the breastfeeding period, you must stop breast-feeding.
Fertility in men
Available data do not indicate an increased risk of malformations or miscarriages if the father takes less methotrexate than 30 mg/week. However, risk cannot be completely ruled out. Methotrexate may be genotoxic. This means that the drug can cause gene mutation. Methotrexate can affect sperm production and can cause congenital malformations. Therefore, you should avoid getting a woman pregnant and donating sperm while taking methotrexate and for at least 6 months after stopping treatment.
Driving and using machines
Side effects from the central nervous system, such as fatigue and dizziness, may occur during treatment with Ebetrex. Therefore, in some cases, the ability to drive vehicles and/or use machines may be impaired. If you feel tired or dizzy, do not drive or use machines.
You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
Ebetrex contains sodium chloride and sodium hydroxide
This medicine contains less than 1 mmol (23 mg) sodium per weekly dose, ie essentially ‘sodium-free’.
3. How to use Ebetrex
Important warning regarding the single dose of Ebetrex (methotrexate):
Ebetrex should only be used once a week in the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, and psoriasis. Using too much Ebetrex (methotrexate) can be life-threatening. Read section 3 of this leaflet very carefully. If you have any further questions on the use of this product, ask your doctor or pharmacist.
Ebetrex should only be prescribed by a doctor with sufficient experience in the drug’s properties and mechanism of action.
Always use this medicine exactly as your doctor or pharmacist has told you. Ask your doctor or pharmacist if you are unsure.
Ebetrex is given only once a week. You will agree with your doctor on a suitable day of the week when you will receive your injection.
Improper intake of Ebetrex can lead to serious side effects, including potentially fatal ones.
The usual dose is:
Patients with rheumatoid arthritis
The recommended starting dose is 7.5 mg methotrexate once a week. Ebetrex is injected as a single dose under the skin, into a muscle, or into a vein (see section “Method of administration and duration of treatment”).
If the effect is still insufficient, the dose of one of Ebetrex may be increased if it is well tolerated. The average weekly dose is 15‑20 mg. In general, a weekly dose of 25 mg should not be exceeded. After the desired treatment goal has been achieved, the dose should, if possible, be reduced to the lowest still effective maintenance dose.
Children and adolescents under 16 years of age with polyarticular forms of juvenile idiopathic arthritis
The recommended dose is 10‑15 mg / m 2 body surface area/week. If the recommended dose is not sufficient, the weekly dose can be increased up to 20 mg / m 2 body surface area/week. However, regular inspections should be carried out more often.
As there are only limited data on intravenous (in a vein) use in children and adolescents, the administration should only be by subcutaneous injection (under the skin) or intramuscularly (in a muscle).
Use is not recommended for children <3 years of age due to a lack of experience in this age group.
Adults with severe forms of psoriasis Vulgaris or psoriatic arthritis
A test dose of 5-10 mg is recommended to evaluate any adverse effects.
This dose can be injected subcutaneously (under the skin), intramuscularly (into a muscle), or intravenously (into a vein).
If no changes in the blood picture have been observed after one week, treatment is continued with approximately 7.5 mg. The dose can be increased gradually (in steps of 5-7.5 mg per week at the same time as monitoring the blood count) until optimal treatment results are achieved. A weekly dose of 20 mg can generally be associated with a significant increase in toxicity. A weekly dose of 30 mg should not be exceeded.
After the desired treatment goal has been achieved, the dose should be reduced weekly, to the lowest still effective maintenance dose.
Patients with renal impairment
For patients with renal impairment, a dose may need to be reduced.
Method of administration and duration of treatment
The attending physician decides how long the treatment should last. Ebetrex is injected once a week! It is recommended that you and your doctor determine a fixed day of the week for injection.
Ebetrex is injected under the skin, into a muscle, or a vein, and must not be given intravenously to children and adolescents.
Treatment with Ebetrex in rheumatoid arthritis, juvenile idiopathic arthritis, psoriasis Vulgaris or psoriatic arthritis is a long-term treatment.
Treatment response can usually be expected 4-8 weeks after starting treatment.
Symptoms may return after stopping treatment with Ebetrex.
Severe forms of psoriasis Vulgaris and psoriatic arthritis ( psoriasis arthropathic)
Treatment response can usually be expected after 2-6 weeks.
Depending on the clinical picture and changes in laboratory values, treatment may then be continued or terminated.
At the beginning of treatment, Ebetrex is injected by healthcare professionals. However, your doctor may decide that it is appropriate for you to learn how to inject Ebetrex under your skin. You will receive appropriate training to be able to do this. Under no circumstances should you try to inject yourself if you have not been trained to do so.
If you use more Ebetrex than you should
Follow your doctor’s dosing recommendations. Do not change the dose on your own.
If you have ingested too much medicine or if e.g. If a child has inadvertently ingested the medicine, contact a doctor, hospital, or the Poison Information Center for risk assessment and advice.
Overdose of methotrexate may cause severe adverse effects. Symptoms of overdose may include bruising or bleeding, abnormal weakness, cold sores, nausea, vomiting, black or bloody stools, bloody coughs or vomiting similar to coffee grounds, and decreased urination. See also section 4.
Take the medicine pack with you if you see a doctor or hospital.
The antidote for an overdose is calcium folinate.
If you forget to use Ebetrex
Do not take a double dose to make up for a forgotten dose, but continue to take your prescribed dose. Ask your doctor for advice.
If you stop using Ebetrex
You should not stop or stop taking Ebetrex unless you have discussed it with your doctor. Contact a doctor immediately if you suspect serious side effects.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
