Contents of the pack
Metoject PEN is indicated for the treatment of:
Rheumatoid arthritis (RA)is a chronic disease of the connective tissue, characterized by inflammation of the synovial membranes (joint membranes). These membranes produce a fluid that acts as a lubricant in many joints. Inflammation causes thickening of the membrane and swelling of the joint.
Juvenile arthritisaffects children and adolescents under 16 years of age. Polyarticular forms are indicated if there is involvement of 5 or more joints in the first 6 months of the disease.
Psoriasisis a chronic and frequent skin disease, characterized by red patches covered with thick, dry, silvery, and adherent scales.
Psoriatic arthritisis a type of arthritis with psoriatic lesions on the skin and nails, especially in the joints of the fingers and toes.
Metoject PEN modifies and slows 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.
Do not use Metoject PEN
Warnings and precautions
Consult your doctor or pharmacist before starting to take Metoject PEN
Special precautions for treatment with Metoject PEN
Methotrexate temporarily affects the production of sperm and eggs, which is reversible in most cases. Methotrexate can cause abortions and severe birth defects. If you are a woman, you should avoid becoming pregnant while using methotrexate and for at least 6 months after finishing treatment. If you are a man, you should avoid fathering a child if you are receiving methotrexate and for at least 3 months after the end of 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 need to perform exams and laboratory tests.
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 find out if you have hepatitis. Additionally, serum albumin (a blood protein), hepatitis status (liver infection), and kidney function will be checked. Your doctor may also decide to perform other liver tests; some of these may involve imaging of the liver, and others may require taking a small tissue sample from the liver to examine it in more detail. Your doctor may also check if you have tuberculosis and may have a chest X-ray or a lung function test.
During treatment
Your doctor may perform the following exams:
It is very important that you attend these scheduled exams.
If the results of any of these tests are abnormal, your doctor will adjust the treatment accordingly.
Elderly patients
Elderly patients being treated with methotrexate should be closely monitored by a doctor to detect possible side effects as soon as possible.
The age-related decline in liver and kidney function and the low body reserves of folic acid in the elderly require a relatively low dose of methotrexate.
Other precautions
Acute pulmonary hemorrhage has been reported with methotrexate in patients with underlying rheumatologic disease. If you cough up blood or spit up blood, you should contact your doctor immediately.
Methotrexate can affect the immune system and vaccination results. It can also affect the results of immunological tests. It can reactivate chronic inactive infections (such as herpes zoster, tuberculosis, hepatitis B or C). During treatment with Metoject PEN, you should not receive live vaccines.
Methotrexate can make the skin more sensitive to sunlight. Avoid intense sunlight and do not use sunbeds or UV lamps without medical advice. To protect your skin from intense sunlight, wear suitable clothing or use a sunscreen with a high protection factor.
During treatment with methotrexate, radiation-induced dermatitis and sunburn (memory reactions) may recur. Psoriatic lesions may worsen during UV radiation and simultaneous administration of methotrexate.
There may be an increase in the size of the lymph nodes (lymphoma), and in such cases, treatment should be discontinued.
Diarrhea can be a side effect of Metoject PEN and requires discontinuation of treatment. If you have diarrhea, talk to your doctor.
Certain brain disorders (encephalopathy/leukoencephalopathy) 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 your caregiver notice the onset or worsening of neurological symptoms, such as general muscle weakness, vision changes, changes in thinking, memory, and orientation that cause confusion and changes in personality, contact your doctor immediately because these may be symptoms of a rare and serious brain infection called progressive multifocal leukoencephalopathy (PML).
Using Metoject PEN with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Keep this in mind also for medicines that you may take in the future.
The effect of treatment may be affected if Metoject PEN is administered at the same time as certain medicines:
Vitamins containing folic acidmay alter the effect of your treatment and should only be taken when advised by your doctor.
Live vaccines should be avoided.
Using Metoject PEN with food, drinks, and alcohol
During treatment with Metoject PEN, you should avoid consuming alcohol and large amounts of coffee, caffeine-containing soft drinks, and black tea.
Pregnancy, breastfeeding, and fertility
Pregnancy
Do not use Metoject PEN during pregnancy or if you are trying to become pregnant. Methotrexate can cause birth defects, harm the fetus, or cause miscarriages. It is associated with malformations of the skull, face, heart, and blood vessels, brain, and limbs. Therefore, it is very important that methotrexate is not administered to pregnant patients or those planning to become pregnant.
In women of childbearing age, any possibility of pregnancy should be excluded with appropriate measures, for example, a pregnancy test before starting treatment.
You should avoid becoming pregnant while taking methotrexate and for at least 6 months 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 should be provided with information about the risk of harmful effects on the child during treatment.
If you wish to become pregnant, consult your doctor, who may refer you to a specialist for information before the planned start of treatment.
Breastfeeding
Stop breastfeeding before and during treatment with Metoject PEN.
Male fertility
Available data do not indicate a higher risk of malformations or miscarriages if the father takes a dose of methotrexate less than 30 mg/week. However, this risk cannot be completely ruled out. Methotrexate can be genotoxic, which means it can cause genetic mutations. Methotrexate can affect sperm production and cause birth defects. Therefore, you should avoid fathering a child or donating sperm while taking methotrexate and for at least 3 months after stopping treatment.
Driving and using machines
Treatment with Metoject PEN can cause side effects that affect the central nervous system, such as fatigue and dizziness. Therefore, the ability to drive or use machines may be affected in certain cases. If you feel tired or drowsy, you should not drive or use machines.
