1. What is Leflunomide Sandoz and what is it used for

Leflunomide Sandoz belongs to a group of anti-rheumatic medicines. It contains the active substance leflunomide.
Leflunomide Sandoz is used to treat adult patients with active rheumatoid arthritis or active psoriatic arthritis.
The symptoms of rheumatoid arthritis include joint inflammation, swelling, difficulty moving, and pain. Other symptoms that affect the whole body are loss of appetite, fever, lack of energy, and anemia (low red blood cell count).
The symptoms of psoriatic arthritis include joint inflammation, swelling, difficulty moving, pain, and redness and scaling of the skin (skin lesions).

2. Important information before taking Leflunomide Sandoz

When not to take Leflunomide Sandoz

  • if the patient has ever had an allergic reaction to leflunomide (especially severe skin reactions, often with fever, joint pain, red spots on the skin, or blisters, e.g., Stevens-Johnson syndrome), peanuts, or soy, or any of the other ingredients of this medicine (listed in section 6) or in case of allergy to teriflunomide (used to treat multiple sclerosis);
  • if the patient has liver function disorders;
  • if the patient has moderate to severe kidney function disorders;
  • if the patient has significantly reduced blood protein levels (hypoproteinemia);
  • if the patient has any immune system disorders (e.g., AIDS);
  • if the patient has bone marrow disorders or a low red blood cell, white blood cell, or platelet count;
  • if the patient has a severe infection;
  • if the patient is pregnant, suspects she is pregnant, or is breastfeeding.

Warnings and precautions

Before starting to take Leflunomide Sandoz, the patient should discuss it with their doctor, pharmacist, or nurse if:

  • the patient has ever had lung inflammation (interstitial lung disease);
  • the patient has ever had tuberculosis or has been in close contact with someone who has or has had tuberculosis in the past. The doctor may order tests to determine if the patient has tuberculosis.
  • the patient is a man and plans to father a child. It cannot be excluded that Leflunomide Sandoz passes into semen, so during treatment with Leflunomide Sandoz, effective contraception should be used. Men planning to father a child should contact their doctor, who may advise stopping Leflunomide Sandoz and prescribing other medicines to quickly and effectively remove Leflunomide Sandoz from the body. Effective removal of Leflunomide Sandoz must be confirmed by blood tests. The decision to father a child can be made no earlier than 3 months after this.
  • the patient is to undergo a specific blood test (calcium level measurement). The results of the calcium level measurement may be falsely lowered.
  • the patient is to undergo or has undergone major surgery, or if they still have an unhealed postoperative wound. Leflunomide Sandoz may hinder wound healing.

Leflunomide Sandoz may occasionally cause blood, liver, lung, or nerve disorders in the hands or feet. It may also cause severe allergic reactions (including drug reaction with eosinophilia and systemic symptoms [DRESS]) or increase the risk of developing a severe infection. More information on this can be found in section 4 (Possible side effects).
DRESS initially presents with flu-like symptoms and a rash on the face, then observes the spread of the rash, high fever, increased liver enzyme activity, and an increased number of a certain type of white blood cell (eosinophilia) visible in blood tests and lymph node enlargement.
Before starting Leflunomide Sandoz, and also regularly during treatment, the doctor will recommend blood tests to monitor the blood count and liver function. The doctor will also recommend regular blood pressure checks, as Leflunomide Sandoz may cause an increase in blood pressure.
If the patient experiences chronic diarrhea of unknown cause, they should consult their doctor. The doctor may order additional tests to determine the diagnosis.
The patient should inform their doctor if they experience skin ulcers during treatment with Leflunomide Sandoz (see section 4).

Children and adolescents

Leflunomide Sandoz should not be used in children and adolescents under 18 years of age.

Leflunomide Sandoz and other medicines

The patient should tell their doctor or pharmacist about all medicines they are taking, have recently taken, or plan to take. This includes medicines obtained without a prescription.
This is especially important if the patient is taking:

  • other medicines used to treat rheumatoid arthritis, such as antimalarial medicines (e.g., chloroquine and hydroxychloroquine), gold preparations given intramuscularly or orally, D-penicillamine, and other immunosuppressive medicines (e.g., methotrexate), as their concurrent use with Leflunomide Sandoz is not recommended;
  • warfarin and other oral anticoagulants, as it is necessary to monitor the patient's condition to reduce the risk of adverse effects of this medicine;
  • teriflunomide (a medicine used to treat multiple sclerosis);
  • repaglinide, pioglitazone, nateglinide, or rosiglitazone (medicines used to treat diabetes);
  • daunorubicin, doxorubicin, paclitaxel, or topotecan (anticancer medicines);
  • duloxetine (a medicine used to treat depression, urinary incontinence, or diabetic neuropathy);
  • alosetron (a medicine used to treat severe diarrhea);
  • theophylline (a medicine used to treat asthma);
  • tizanidine (a muscle relaxant);
  • oral contraceptives (containing ethinylestradiol and levonorgestrel)
  • cefaclor, benzylpenicillin (penicillin G), ciprofloxacin (antibiotics)
  • indomethacin, ketoprofen (medicines used to treat pain and inflammation)
  • furosemide (a diuretic used to treat heart disease)
  • zidovudine (a medicine used to treat HIV infection)
  • rosuvastatin, simvastatin, atorvastatin, pravastatin (medicines used to treat high cholesterol)
  • sulfasalazine (a medicine used to treat inflammatory bowel disease or rheumatoid arthritis)
  • cholestyramine (used to reduce high cholesterol) or activated charcoal, as they may reduce the absorption of Leflunomide Sandoz;

If the patient is taking non-steroidal anti-inflammatory drugs (NSAIDs) and/or corticosteroids, they may continue to take them after starting treatment with Leflunomide Sandoz.

Vaccinations

If the patient plans to be vaccinated, they should consult their doctor. Some vaccines should not be used during or for some time after treatment with Leflunomide Sandoz.

Leflunomide Sandoz with food, drink, and alcohol

Leflunomide Sandoz can be taken with or without food.
During treatment with Leflunomide Sandoz, it is not recommended to drink alcohol, as consuming alcohol while taking Leflunomide Sandoz may increase the risk of liver damage.

Pregnancy, breastfeeding, and fertility

Do nottake Leflunomide Sandoz if the patient is or may be pregnant.
If the patient is pregnant or becomes pregnant during treatment with Leflunomide Sandoz, the risk of severe birth defects in the child increases. Women of childbearing age should not take Leflunomide Sandoz unless they use effective contraception.
Women planning to become pregnant after stopping treatment with Leflunomide Sandoz should inform their doctor, as it is necessary to ensure that no traces of Leflunomide Sandoz remain in the body. This may take up to 2 years, but this time can be shortened to a few weeks by taking medicines that accelerate the removal of Leflunomide Sandoz from the body.
In any case, the patient should undergo the necessary blood tests to ensure that Leflunomide Sandoz has been effectively removed from the body. After this time, the patient should wait at least one month before planning a pregnancy.
The doctor will provide further information on blood tests.
If the patient suspects they have become pregnant while taking Leflunomide Sandoz or within 2 years of stopping it, they must immediatelycontact their doctor and have a pregnancy test. If the test result confirms pregnancy, the doctor may advise treatment with certain medicines to quickly and effectively remove Leflunomide Sandoz from the body, which may reduce the risk to the child.
Do nottake Leflunomide Sandoz while breastfeeding, as leflunomide passes into breast milk.

Driving and using machines

Leflunomide Sandoz may cause dizziness that impairs concentration and reaction speed. If the patient experiences dizziness, they should not drive or operate machinery.

Leflunomide Sandoz contains lactose monohydrate, soy lecithin, and sodium

If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.
