Leflunomide is a disease‑modifying antirheumatic drug used in the management of inflammatory arthritis conditions.

- Rheumatoid arthritis: reduces disease activity, joint swelling and slows structural damage. - Psoriatic arthritis: improves joint pain and skin lesions associated with the disease. - Adult patients with active disease: provides long‑term disease‑modifying benefits when conventional therapy is insufficient.

Leflunomide may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Diarrhea: mild to moderate gastrointestinal upset. - Nausea: occasional feeling of sickness. - Elevated liver enzymes: transient increase in hepatic transaminases. - Headache: mild tension‑type headaches. - Hypertension: modest rise in blood pressure. - Rash: non‑specific skin eruptions.

Serious or Rare Side Effects: - Severe liver injury: hepatitis or hepatic failure requiring monitoring. - Bone marrow suppression: neutropenia, anemia or thrombocytopenia. - Pulmonary toxicity: interstitial lung disease or pneumonitis. - Severe cutaneous reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Infections: opportunistic infections due to immunosuppression.

Before initiating Leflunomide therapy, several safety considerations should be reviewed. - Pregnancy: contraindicated; drug is classified as pregnancy category X. - Liver function: assess baseline hepatic enzymes and monitor regularly. - Hematology: obtain complete blood count before treatment and during therapy. - Infections: screen for active infections and avoid initiating in immunocompromised patients. - Vaccinations: administer required live vaccines prior to starting therapy. - Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and light.

Leflunomide can interact with other medicines, influencing efficacy or toxicity.

Major Interactions (Avoid): - Methotrexate: combined use may increase hepatotoxic risk. - Strong CYP1A2 inhibitors (e.g., fluvoxamine): can raise leflunomide plasma levels. - Warfarin: may enhance anticoagulant effect, requiring close INR monitoring.

Moderate Interactions (Monitor Closely): - Azathioprine: additive bone marrow suppression potential. - Live vaccines: reduced efficacy and increased infection risk. - Cholesterol‑lowering agents (statins): possible increase in muscle toxicity.
