Warnings and precautions

Consult your doctor or pharmacist before starting to take Leflunomida Stada, especially:

• if you have ever hadinterstitial lung disease.
• if you have ever had tuberculosis or have been in contact with someone who has or has had tuberculosis. Your doctor may perform tests to determine if you have tuberculosis.
• if you are amaleand wish to have children. As leflunomida may pass into semen, reliable contraceptive methods should be used during treatment with this medication. Males who wish to have children should contact their doctor, who will advise them to interrupt treatment with leflunomida and take certain medications to quickly and sufficiently eliminate leflunomida from their body. In this case, a blood test will be necessary to ensure that leflunomida has been eliminated sufficiently from their body, and then they should wait at least 3 months before attempting to have children.
• if you are to undergo a specific blood test (calcium levels). Falsely low calcium levels may be detected.
• if you are to undergo or have recently undergone a major surgical procedure, or if you still have an open wound after a surgical procedure. Leflunomida may impair wound healing.

Consult your doctor if you experience chronic diarrhea of unknown origin. You may undergo additional tests to establish a differential diagnosis.

Leflunomida 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 a pharmacological reaction with eosinophilia and systemic symptoms (DRESS)), or increase the risk of a serious infection. For more information on these adverse effects, see section 4 (Possible adverse effects). In DRESS, initially, symptoms similar to the flu and facial rash appear, accompanied by high temperature, elevated liver enzymes in blood tests, and increased eosinophils, and inflamed lymph nodes.

Your doctor will performblood testsat regular intervals, before and during treatment with leflunomida, to monitor your blood cells and liver. Your doctor should also regularly check your blood pressure, as leflunomida may cause an increase in blood pressure.

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

• warfarin and other oral medications used as anticoagulants, as a control is necessary to reduce the risk of adverse effects of this medication
• teriflunomida for multiple sclerosis
• repaglinida, pioglitazona, nateglinida, or rosiglitazona for diabetes
• daunorubicina, doxorubicina, paclitaxel, or topotecán for cancer

Taking Leflunomida Stada with food, drinks, and alcohol

It is not recommended to consume alcohol during treatment with leflunomida. Drinking alcohol during treatment may increase the risk of liver damage.

Pregnancy and lactation

Do not take Leflunomida Stada if you are or think you may bepregnant.Leflunomida Stada increases the risk of having a child with severe malformations. Women of childbearing age should not take leflunomida without using effective contraceptive methods.

Inform your doctor if you plan to become pregnant after interrupting treatment with leflunomida, as it is necessary to ensure that there are no remaining leflunomida residues 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 leflunomida from the body. In any case, a blood test will be necessary to confirm that leflunomida has been eliminated sufficiently from your body, and once this test is done, 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 leflunomida or in the 2 years after treatment, you must 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 quickly and sufficiently eliminate leflunomida from your body, and thus reduce the risk to your child.
