Metojectis indicated for the treatment of:

• active rheumatoid arthritis in adult patients,
• severe active polyarticular juvenile idiopathic arthritis when the response to nonsteroidal anti-inflammatory drugs (NSAIDs) has not been adequate,
• moderate to severe psoriasis in adult patients, and severe psoriatic arthritis in adults,
• mild to moderate Crohn's disease in adult patients when an adequate treatment with other medications is not possible.

Therheumatoid arthritis(RA)is a chronic collagen disease, characterized by the inflammation of the synovial membranes (membranes of the joints).These membranes produce a liquid that acts as a lubricant in many joints. Inflammation causes the thickening of the membrane and the swelling of the joint.

Thejuvenile arthritisaffects children and adolescents under 16 years old.The polyarticular forms are indicated if there is involvement of 5 or more joints in the first 6 months of the disease.

Thepsoriasisis a chronic and frequent skin disease, characterized by red patches covered by thick, dry, silver, and adherent scales.

Thepsoriatic arthritisis a type of arthritis with psoriatic lesions on the skin and nails, especially in the joints of the fingers and toes.

MetojectPEN modifies and delays the progression of the disease.

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

• If you have severe liver or kidney disease or blood disorders,
• If you regularly take large amounts of alcohol,
• If you have a serious infection, such as tuberculosis, HIV, or other immunodeficiency syndromes,
• If you have mouth ulcers, stomach ulcers, or intestinal ulcers,

• If you have liver function problems,
• If you have dehydration (loss of fluids).
• If you have diabetes mellitus and are receiving insulin treatment.

Special precautions for treatment withMetojectPEN

Methotrexate temporarily affects the production of sperm and eggs, which is usually reversible. Methotrexate can cause serious birth defects and miscarriages. If you are a woman, avoid becoming pregnant while using methotrexate and for at least 6 months after stopping treatment.If you are a man, avoid fathering a child while receiving methotrexate and for at least 3months after stopping treatment.See also section "Pregnancy, breastfeeding and fertility".

Follow-up tests and recommended precautions

Even if methotrexate is used in low doses, serious side effects can occur. To detect them in time, your doctor will perform tests and blood analyses.

Before starting treatment

Before starting treatment, you will have blood tests to check that you have enough blood cells. You will also have blood tests to check liver function and to see if you have hepatitis. In addition, your albumin serum (a blood protein) will be checked, as well as your liver and kidney function. Your doctor may also decide to perform other liver tests; some of these may be images of the liver, and others may require a small sample of liver tissue to be examined in more detail. Your doctor may also check if you have tuberculosis, and may perform a chest X-ray or a lung function test.

During treatment

Your doctor may perform the following tests:

• Examination of the oral cavity and pharynx to identify changes in the mucous membrane, such as inflammation or ulceration.
• Blood tests/complete blood counts with white blood cell count and measurement of methotrexate serum levels.
• Blood tests to check liver function.
• Imaging tests to check liver function.
• Extraction of a small sample of liver tissue for further examination.
• Blood tests to check kidney function.
• Control of the respiratory tract, and if necessary, a lung function test.

It is very important that you attend these scheduled tests.

If the results of any of these tests are abnormal, your doctor will adjust your treatment accordingly.

Older patients

Older patients receiving methotrexate should be closely monitored by a doctor to detect any possible side effects as soon as possible.

The deterioration of liver and kidney function related to age and low vitamin B12 reserves in older age requires a relatively low dose of methotrexate.

Other precautions

Methotrexate has been associated with acute pulmonary hemorrhage in patients with underlying rheumatological disease. If you notice blood when coughing or spitting, you should contact your doctor immediately.

Methotrexate can affect the immune system and vaccine results. It can also affect the results of immunological tests. It can reactivate chronic inactive infections (such as herpes zoster ["cold sores"], tuberculosis, hepatitis B or C).During treatment with MetojectPEN, do not receive vaccines made with attenuated microorganisms.

Methotrexate can make the skin more sensitive to sunlight. Avoid intense sunlight and do not use sunbeds or ultraviolet lamps without medical advice. To protect your skin from intense sunlight, wear suitable clothing or use a high-protection sunscreen.

During methotrexate treatment, radiation-induced dermatitis and sunburns (memory reactions) may recur. Psoriatic lesions may intensify during UV radiation and simultaneous methotrexate administration.

Lymph node enlargement (lymphoma) may occur, and in this case, treatment should be suspended.

Diarrea can be a side effect ofMetojectPENand requires suspension of treatment. If you have diarrhea, talk to your doctor.

Certain brain disorders (encephalopathy/leucoencephalopathy) have been reported in cancer patients treated with methotrexate. It cannot be ruled out that these side effects may occur when methotrexate is used to treat other diseases.

If you, your partner, or caregiver notice the onset or worsening of neurological symptoms, such as general muscle weakness, visual disturbances, changes in thinking, memory, and orientation that cause confusion, and changes in personality, contact your doctor immediately, as these may be symptoms of a rare and serious brain infection called progressive multifocal leukoencephalopathy (PML).

Use of MetojectPEN with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medicine. Also, consider this for medicines you may takein the future.

The effect of treatment may be affected if MetojectPEN is administered at the same time as certain medicines:

•Antibioticssuch as: tetracyclines, chloramphenicol, non-absorbable broad-spectrum antibiotics, penicillins, glucopetides, sulfonamides, ciprofloxacin, and cefalotin (medicines to prevent or combat certain infections).

•Non-steroidal anti-inflammatory drugsor salicylates (pain and inflammation medicines such as aspirin, diclofenac, and ibuprofen or pyrazolones).

•Metamizol (synonyms novaminsulfon and dipirona) (medicine for intense pain and/or fever).

•Probenecid(medicine for gout).

•Weak organic acids such as diuretics of the asa.

•Medicines that can cause adverse effects on the bone marrow, such as trimethoprim-sulfamethoxazole (an antibiotic) and pyrimethamine.

•Othermedicines usedto treatrheumatoid arthritissuch as leflunomide, sulfasalazine, and azathioprine.

•Ciclosporina (to suppress the immune system).

•Mercaptopurine (a cytostatic medicine).

•Retinoids (medicines for psoriasis and other skin diseases).

•Theophylline (medicine for asthma and other lung diseases).

•Some medicines for stomach problems such as omeprazole and pantoprazole.

•Hypoglycemics (medicines used to reduce blood sugar levels).

Vitamins containingfolatemay alter the effect of your treatment and should only be taken when advised by your doctor.

Do not vaccinate with vaccines made with attenuated microorganisms.

Use of MetojectPEN with food, drinks, and alcohol

During treatment with MetojectPEN, avoid consuming alcohol, and large amounts of coffee, caffeinated soft drinks, and black tea.

Pregnancy, breastfeeding, and fertility

Pregnancy

Do not useMetojectPENduring pregnancy or if you are trying to become pregnant. Methotrexate can cause birth defects, harm the fetus, or cause miscarriages. It is associated with skull, facial, heart, and blood vessel malformations, brain, and limb malformations. Therefore, it is very important that methotrexate is not administered to pregnant patients or those planning to become pregnant.

In fertile women, any possibility of pregnancy should be excluded with appropriate measures, for example, a pregnancy test before starting treatment.

Avoid becoming pregnant while taking methotrexate and for at least 6months after stopping treatment, using reliable contraceptive methods during this time (see also section "Warnings and precautions").

If you become pregnant during treatment or suspect you may be pregnant, consult your doctor as soon as possible. You will be offered information on the risk of harm to the child during treatment.

If you want to become pregnant, consult your doctor, who may refer you to a specialist to inform you before starting treatment.

Breastfeeding

Stop breastfeeding before and during treatment with MetojectPEN.

Male fertility

The available data do not indicate a higher risk of malformations or miscarriages if the father takes a methotrexate dose of less than 30mg/week. However, this risk cannot be completely ruled out. Methotrexate can be genotoxic, meaning it can cause genetic mutations. Methotrexate can affect sperm production and cause birth defects. Therefore, you should avoid fathering a child or donating semen while taking methotrexate and for at least 3months after stopping treatment.

Driving and operating machinery

Treatment with MetojectPEN may cause side effects that affect the central nervous system, such as fatigue and dizziness. Therefore, your ability to drive or operate machinery may be affected in some cases. If you feel tired or drowsy, do not drive or operate machinery.
