1. What Trexan Neo is and what it is used for

The active substance of Trexan Neo tablets, methotrexate, has the following properties:

• inhibits the growth of certain cells in the body that multiply rapidly
• reduces the activity of the immune system (the body's defense mechanism)

Methotrexate is used:

• to treat active rheumatoid arthritis in adults
• to treat severe, treatment-resistant psoriasis that does not respond to other treatments, such as phototherapy, PUVA, and retinoids in adults
• to treat severe psoriatic arthritis in adults
• as maintenance therapy for acute lymphoblastic leukemia (ALL) in adults, adolescents, and children aged 3 years and older.

Your doctor will explain how Trexan Neo tablets can help you with your condition.

2. Before you take Trexan Neo

When not to take Trexan Neo:

• if you are allergic (hypersensitive) to methotrexate or any of the other ingredients of this medicine (listed in section 6)
• if you are breastfeeding, and also during pregnancy, if you are taking the medicine for non-oncological indications (for the treatment of non-cancerous diseases) (see section "Pregnancy, breastfeeding, and fertility")
• if you have severe liver or kidney disease (the severity of the disease will be determined by your doctor)
• if you have bone marrow or severe blood disorders
• if you have severe acute or chronic infections or immunodeficiency syndrome
• if you have oral mucositis or oral ulcers
• if you have stomach or intestinal ulcers
• if you have alcoholic disease
• if you have recently received a live vaccine or plan to receive one

Warnings and precautions

Important warning about Trexan Neo dosing (methotrexate):

In the treatment of rheumatoid arthritis, psoriasis, or psoriatic arthritis, Trexan Neo should be taken only once a week. Taking too high a dose of Trexan Neo (methotrexate) can lead to death. You should read the contents of section 3 of this leaflet very carefully. If you have any questions, you should consult your doctor or pharmacist before taking this medicine.
Before starting treatment with Trexan Neo, you should discuss the following with your doctor, pharmacist, or nurse:

• if you have ever had liver or kidney disease
• if you have a hidden, chronic infection (e.g., tuberculosis, viral hepatitis B or C, shingles), due to the possibility of reactivation of these diseases
• if you are in poor general condition
• if you have respiratory function disorders
• if you are severely overweight
• if you have fluid accumulation in the abdominal cavity (ascites) or in the space between the lungs and the chest wall (pleural effusion)
• if you have diabetes treated with insulin
• if you are dehydrated or have disorders leading to dehydration (e.g., vomiting, diarrhea, constipation, oral mucositis)

During methotrexate treatment, cases of acute bleeding from the lungs have been reported in patients with underlying rheumatologic disease. If you experience coughing up blood or bloody sputum, you should immediately consult your doctor.
A side effect of Trexan Neo may be diarrhea, which requires discontinuation of treatment.
If you experience diarrhea, you should consult your doctor.
Methotrexate has a temporary effect on sperm and egg production.
Methotrexate may cause miscarriage and severe birth defects. Women should avoid becoming pregnant while taking methotrexate and for at least 6 months after treatment ends. Men taking methotrexate should avoid fathering a child or donating sperm during treatment and for at least 3 months after treatment ends. See also the section "Pregnancy, breastfeeding, and fertility".
Radiation therapy during Trexan Neo treatment may increase the risk of soft tissue or bone necrosis.
During methotrexate treatment, previously radiation-induced skin changes may recur (radiation dermatitis) or sunburn (recall reactions).
Methotrexate may increase skin sensitivity to sunlight. You should avoid intense sun exposure and not use a sunbed or sunlamp without consulting your doctor.
To protect your skin from intense sunlight, you should wear appropriate clothing or use a sunscreen with a high protection factor.
In patients receiving low-dose methotrexate, lymphoma (lymph node cancer) may occur. In such cases, treatment should be discontinued.
If you, your partner, or caregiver notice new or worsening neurological symptoms, including general muscle weakness, vision disturbances, changes in thinking, memory, and orientation leading to disorientation and personality changes, you should immediately consult your doctor, as these may be symptoms of a very rare, serious brain infection called progressive multifocal leukoencephalopathy (PML).
In patients with cancer receiving methotrexate, certain other brain disorders (encephalopathy/leukoencephalopathy) have been reported. Such side effects cannot be ruled out when methotrexate is used to treat other diseases.
Recommended tests and precautions
Even with low doses of methotrexate, severe side effects may occur.
To detect these side effects early, your doctor will need to perform tests and laboratory tests.
Before starting treatment:

• Before starting treatment, your doctor will recommend blood tests to check if your blood cell count is sufficient to administer the medicine. Your doctor will also recommend blood tests to check liver function and to determine if you have hepatitis. Additionally, blood tests will be performed to check the albumin level in your blood serum (a protein in the blood), the degree of liver inflammation (liver infection), and kidney function. Your doctor may also decide to perform other liver tests, some of which may be imaging tests of the liver, and others may require taking a small tissue sample from the liver for further examination. Your doctor may also check if you have tuberculosis and recommend a chest X-ray or lung function tests.

During treatment:

• Your doctor may recommend the following tests:
• examination of the mouth and throat to check for changes in the mucous membranes, such as inflammation or ulcers
• blood tests/morphology with blood cell count and determination of methotrexate level in blood serum
• liver function tests
• imaging tests to assess liver condition
• taking a small tissue sample from the liver for further examination
• kidney function tests
• monitoring of the respiratory tract and, if necessary, performing lung function tests

It is very important that you attend all scheduled blood tests.
If the results of any of these tests are abnormal, your doctor will adjust your treatment accordingly.

Children, adolescents, and elderly patients

During Trexan Neo therapy, children, adolescents, and elderly patients treated with methotrexate should be under close medical supervision to detect any potential side effects as early as possible.
In elderly patients, it is necessary to use a relatively low dose of methotrexate due to impaired liver and kidney function and lower folate reserve in the elderly.
The use of this medicine is not recommended in children under 3 years of age due to insufficient experience in this age group.

Trexan Neo and other medicines

Other medicines taken at the same time may affect the efficacy and safety of Trexan Neo.
Trexan Neo may also affect the efficacy and safety of other medicines.
You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Remember to inform your doctor about taking Trexan Neo if you are prescribed another medicine. It is especially important to inform your doctor if you are taking:

• metamizole (synonyms: novaminsulfone and dipyrone) [a strong pain reliever and/or antipyretic]
• certain antibiotics (medicines used to prevent or treat certain infections), such as penicillins, sulfonamides, ciprofloxacin, cephalothin, trimethoprim/sulfamethoxazole, tetracycline, and chloramphenicol. For example, penicillins, such as amoxicillin, may reduce methotrexate excretion, leading to increased side effects
• other medicines used to treat rheumatoid arthritis or psoriasis, such as leflunomide, sulfasalazine, and azathioprine
• certain pain relievers and/or anti-inflammatory medicines, known as nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, diclofenac, salicylates, such as acetylsalicylic acid)
• pyrimethamine (a medicine used to prevent and treat malaria)
• anticancer medicines (e.g., mercaptopurine, 5-fluorouracil, doxorubicin, and procarbazine)
• antiepileptic medicines (medicines that prevent seizures)
• omeprazole or pantoprazole (medicines that reduce stomach acid production)
• diuretics (medicines that increase urine production)
• medicines that lower blood sugar levels, such as metformin
• cholestyramine (a medicine that binds bile acids, which may be used to lower cholesterol levels in the blood)
• cyclosporine (a medicine that suppresses or prevents immune responses)
• retinoids (medicines used to treat psoriasis and other skin diseases)
• oral contraceptives
• barbiturates (sleeping medicines)
• sedatives
• nitrous oxide (used for general anesthesia)
• probenecid (a medicine used to treat gout)
• theophylline (a medicine used to treat respiratory diseases)
• vitamin preparations and other products containing folic acid, folinic acid, and their derivatives
• vaccines containing live microorganisms

Trexan Neo with food, drink, and alcohol

During Trexan Neo therapy, you should avoid alcohol, as well as large amounts of coffee, caffeine-containing beverages, and black tea.
During Trexan Neo treatment, you should drink plenty of fluids, as dehydration (reduced water content in the body) may increase the side effects of methotrexate.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
Pregnancy
Trexan Neo should notbe used during pregnancy unless your doctor has recommended it for cancer treatment.
Methotrexate may cause birth defects, harm the unborn child, or lead to miscarriage. This is associated with developmental abnormalities of the skull, face, heart, and blood vessels, brain, and limbs. Therefore, it is very important not to give methotrexate to pregnant women or women planning to become pregnant, unless the medicine is used for cancer treatment.
In non-oncological indications, in women of childbearing age, before starting treatment, you should rule out the possibility of pregnancy, e.g., by performing a pregnancy test.
You should not take Trexan Neo if you are trying to become pregnant. You should avoid becoming pregnant while taking methotrexate and for at least 6 months after treatment ends. During this time, you should use effective contraception (see also the section "Warnings and precautions").
If you become pregnant during treatment or think you may be pregnant, you should consult your doctor as soon as possible. If you become pregnant during treatment, you should receive counseling about the risk of methotrexate harming your child.
If you plan to become pregnant, you should consult your doctor, who may refer you to a specialist for counseling before planned treatment begins.
Breastfeeding
Since methotrexate passes into breast milk, you should not breastfeed while taking this medicine.
If your doctor considers it necessary to treat you with methotrexate during breastfeeding, you should stop breastfeeding.
Male fertility
Available data do not indicate an increased risk of birth defects or miscarriages after the father has taken methotrexate at a dose below 30 mg/week. However, this risk cannot be entirely ruled out; there is also no information on higher doses of methotrexate. Methotrexate may have genotoxic effects, meaning it may cause genetic mutations. Methotrexate may affect sperm production, which is associated with the possibility of birth defects.
You should avoid impregnating your partner or donating sperm while taking methotrexate and for at least 3 months after treatment ends.
Due to the potential risk of infertility and genetic mutations with higher doses of methotrexate, typically used in cancer treatment, it may be recommended to store sperm obtained before starting treatment (see also the section "Warnings and precautions").
Before taking any medicine, consult your doctor or pharmacist.

Driving and using machines

During Trexan Neo therapy, you may experience fatigue and dizziness. If these symptoms occur, you should not drive or operate machinery.

Trexan Neo contains lactose

These tablets contain lactose. If you have been diagnosed with intolerance to some sugars, you should consult your doctor before taking this medicine.

3. How to take Trexan Neo

Your doctor will calculate the required dose based on your body surface area. Your doctor will decide on the appropriate dose. For more information, consult your doctor.
Special patient populations
In elderly patients and those with impaired liver or kidney function, a reduced dose is usually used, depending on the doctor's decision. See also section 2: "When not to take Trexan Neo".

Use in children and adolescents

In children and adolescents undergoing maintenance therapy for acute lymphoblastic leukemia, the doctor will calculate the dose individually based on body surface area.

Safe handling of Trexan Neo tablets

Follow the appropriate procedures for handling cytotoxic agents. Anyone in contact with methotrexate should wash their hands before and after administering the dose. When handling methotrexate tablets, use disposable gloves. Women who are pregnant, planning to become pregnant, or breastfeeding should avoid contact with methotrexate.
Avoid contact with the skin and mucous membranes. If methotrexate comes into contact with the skin or mucous membranes, wash the affected area thoroughly with soap and water.
Advise parents, caregivers, and patients to store methotrexate in a place inaccessible to children, preferably in a locked cabinet.
Accidental ingestion by a child can lead to death.

Overdose of Trexan Neo

If you (or someone else) have taken a higher dose of Trexan Neo than recommended, you should immediately consult your doctor or the nearest hospital emergency department.
Methotrexate overdose can lead to severe toxic reactions, including death.
Symptoms of overdose may include: bleeding tendency or bleeding, unusual weakness, oral ulcers, nausea, vomiting, black or bloody stools, coughing up blood or coffee-ground-like vomit, and decreased urine output. See also section 4: "Possible side effects".
When going to your doctor or hospital emergency department, take the medicine package with you.
If you have taken too much methotrexate, you will be given calcium folinate to alleviate methotrexate side effects.

Missed dose of Trexan Neo

If you miss a dose, take it as soon as possible, provided that you remember within 2 days. However, if more than 2 days have passed since the scheduled dose, consult your doctor.
Do not take a double dose to make up for a missed dose.
Before going on vacation or a trip, make sure you have enough medicine.

Stopping Trexan Neo treatment

Unless your doctor recommends otherwise, do not stop taking Trexan Neo.
If you need to stop taking Trexan Neo, your doctor will decide on the best method of discontinuation.
If you have any further questions about taking this medicine, consult your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, Trexan Neo can cause side effects, although not everybody gets them.
Generally, the frequency and severity of methotrexate side effects are dose- and administration frequency-related. Most side effects are reversible if detected early.
Tell your doctor immediatelyif you experience any of the following symptoms, as they may indicate a serious, potentially life-threatening side effect that requires special treatment:

• dry cough and/or chest pain or difficulty breathing, shortness of breath, chest pain, or fever
• coughing up blood or bloody sputum
• unusual bleeding (including bloody vomiting), bruising, or nosebleeds
