Lefluartil belongs to a group of medicines called anti-rheumatic medicines.

Lefluartil 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 affecting the whole body include loss of appetite, fever, lack of energy, and anemia (reduction in the number of red blood cells).

The symptoms of active psoriatic arthritis include joint inflammation, swelling, difficulty moving, pain, red plaques, and scaly skin (skin lesions).

Do not take Lefluartil

• if you have ever experienced an allergic reaction to leflunomide (especially a severe skin reaction, these severe reactions are usually accompanied by fever, joint pain, red skin patches, or blisters, for example, Stevens-Johnson syndrome) or to any of the other components of Lefluartil,
• if you have any liver problems,
• if you have moderate to severe kidney problems,
• if you have a severe decrease in the concentration of proteins in your blood (hypoproteinemia), if you have any condition that affects your immune system (for example, HIV),
• if you have any problems with your bone marrow or if you have a reduced number of red or white blood cells in your blood or a reduced number of platelets,

• if you have a severe infection,
• if you are pregnant or breastfeeding.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Lefluartil:

• if you have ever experienced inflammation of the lungs (interstitial lung disease)
• if you have ever had tuberculosis or if you have been in close contact with someone who has or has had tuberculosis. Your doctor may perform tests to see if you have tuberculosis
• if you are a male and wish to have children.As Lefluartil may pass into the semen, reliable contraceptive methods should be used during treatment with Lefluartil.

Males who wish to have children should contact their doctor, who may advise them to interrupt treatment with Lefluartil and take certain medications to quickly and sufficiently eliminate Lefluartil from their body. In this case, a blood test will be necessary to ensure that Lefluartil has been eliminated sufficiently from their body, and then they should wait at least 3 months before trying to have children.

• if a specific blood test (calcium level) is planned. A false decrease in calcium levels may be detected.
• if you are scheduled to undergo or have recently undergone a major surgical procedure, or if you still have an open wound after a surgical procedure. Lefluartil may impair wound healing.

Lefluartil may occasionally cause some problems in the blood, liver, lungs, or nerves in the arms or legs. It may also cause some severe allergic reactions (including drug eruption with eosinophilia and systemic symptoms [DRESS syndrome]), or increase the risk of a severe infection. For more information on these adverse effects, see section 4 (Possible adverse effects).

DRESS syndrome appears initially with symptoms similar to the flu and a skin rash on the face, followed by a widespread skin rash with fever, elevated liver enzymes in the blood, and an increase in a type of white blood cell (eosinophilia) and enlarged lymph nodes.

Your doctor will perform blood tests at regular intervals, before and during treatment with Lefluartil, to monitor blood cells and the liver. Your doctor should also regularly check your blood pressure as Lefluartil may cause an increase in blood pressure.

Consult your doctor if you experience chronic diarrhea of unknown origin. Additional tests may be performed to establish a differential diagnosis.

Inform your doctor if you develop a skin ulcer during treatment with Lefluartil (see section 4).

Use in children:

Lefluartil is not recommended for use in children and adolescents under 18 years of age.

Use of other medications

Inform your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription.

This is especially important if you are taking:

• other medications for rheumatoid arthritis, such as antimalarials (for example: chloroquine and hydroxychloroquine), gold salts administered intramuscularly or orally, D-penicillamine, azathioprine, and other immunosuppressive medications (for example: methotrexate), as the use of these combinations is not recommended.
• warfarin (used as an anticoagulant), as a control is necessary to reduce the risk of adverse effects of this medication
• teriflunomide for multiple sclerosis
• repaglinide, pioglitazone, nateglinide, or rosiglitazone for diabetes
• daunorubicin, doxorubicin, paclitaxel, or topotecan for cancer
• duloxetine for depression, urinary incontinence, or renal insufficiency in diabetics
• alosetron for severe diarrhea control
• theophylline for asthma
• tizanidine, a muscle relaxant
• oral contraceptives (containing ethinylestradiol and levonorgestrel)
• cefaclor, benzylpenicillin (penicillin G), ciprofloxacin for infections
• indometacin, ketoprofen for pain or inflammation
• furosemide for heart disease (diuretic, diuretic pills)
• zidovudine for HIV infection
• rosuvastatin, simvastatin, atorvastatin, pravastatin for hypercholesterolemia (high cholesterol)
• sulfasalazine for inflammatory bowel disease or for rheumatoid arthritis
• a medication called cholestyramine (used to reduce high cholesterol) or activated charcoal, as these medications may reduce the amount of Lefluartil absorbed by the body.

If you are taking a nonsteroidal anti-inflammatory drug (NSAID) and/or corticosteroids, you may continue to take them after starting treatment with Lefluartil.

Vaccinations

Consult your doctor if you need to be vaccinated. Some vaccines cannot be administered while you are being treated with Lefluartil or for a certain period after treatment is completed.

Taking Lefluartil with food and drinks

Pregnancy and breastfeeding

Do not takeLefluartil if you are or think you may bepregnant.Women of childbearing age should not take

Lefluartil without using effective contraceptive methods.

Inform your doctor if you plan to become pregnant after interrupting treatment with Lefluartil, as it is necessary to ensure that there are no remaining traces of Lefluartil in your body before becoming pregnant. The elimination of the medication from the body may take up to 2 years. This time interval may be reduced to a few weeks by taking certain medications that accelerate the elimination of Lefluartil from the body. In any case, a blood test should be performed before becoming pregnant to confirm that Lefluartil has been eliminated sufficiently from your body, and once this test has been performed, you should wait at least 1 month before becoming pregnant.

For more information on laboratory tests, contact your doctor.

If you suspect that you may be pregnant during treatment with Lefluartil or in the 2 years after treatment, you should contact your doctor immediately for a pregnancy test. If the test confirms that you are pregnant, your doctor may suggest that you start taking certain medications to accelerate the elimination of Lefluartil from your body, and thus reduce the risk to your child.
