# LEFLUNOMIDE 20 MG ## Short Description **Leflunomide 20 mg** is a prescription **disease-modifying antirheumatic drug (DMARD)** used primarily to treat **active rheumatoid arthritis (RA)**. It helps reduce joint inflammation, pain, swelling, and stiffness and can slow the progression of joint damage. Leflunomide works by suppressing certain immune-system processes that contribute to chronic inflammation. Because it affects the immune system and has a long-lasting active metabolite, treatment requires appropriate medical monitoring. --- ## Key Benefits * Helps reduce **joint pain, swelling, and stiffness** associated with rheumatoid arthritis. * Helps improve physical function and mobility. * Helps control excessive immune-system activity involved in rheumatoid arthritis. * Can help **slow the progression of structural joint damage**. * Provides a long-term disease-modifying treatment option. * May be used alone or in combination with other DMARDs when prescribed by a specialist. > **Important:** Leflunomide is not intended to provide immediate pain relief. Its disease-modifying effects develop over time. --- ## Uses / Indications Leflunomide is primarily used for: * **Active rheumatoid arthritis** * Active psoriatic arthritis in some countries and according to local approval It may be prescribed when long-term control of inflammatory arthritis is required. ### Rheumatoid Arthritis Leflunomide can help: * Reduce inflammation * Reduce joint tenderness and swelling * Improve physical function * Slow the progression of joint damage The approved indications may vary depending on the country and regulatory authority. --- ## How It Works Leflunomide is an **immunomodulatory medicine**. After administration, it is converted to its active metabolite, **teriflunomide**. Teriflunomide inhibits an enzyme called **dihydroorotate dehydrogenase (DHODH)**, which is involved in the production of pyrimidines. This reduces the ability of activated immune cells, particularly rapidly proliferating lymphocytes, to multiply. As a result, leflunomide helps reduce the abnormal immune activity responsible for inflammation and joint damage in rheumatoid arthritis. --- ## Dosage & Administration * Take **Leflunomide 20 mg exactly as prescribed by your doctor**. * It may be taken **with or without food**. * Take it at approximately the same time each day. * Swallow the tablet with water. * Do not crush or chew the tablet unless specifically instructed. * Do not change the dose without medical advice. ### Typical Adult Regimen A commonly used maintenance dose is: **20 mg once daily.** Some patients may initially receive a **loading dose**, but loading doses are not appropriate for everyone because they may increase adverse effects. Your doctor will determine whether a loading dose is suitable. ### Important Leflunomide has a **very long elimination half-life**. Its active metabolite can remain in the body for an extended period after treatment is stopped. A specific **accelerated drug-elimination procedure** may therefore be required in certain situations, such as serious toxicity, pregnancy, or before conception. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses together.** --- ## Side Effects Common side effects may include: * Diarrhea * Nausea * Headache * Abdominal discomfort * Indigestion * Increased blood pressure * Hair thinning or hair loss * Skin rash * Dry skin * Reduced appetite * Mild respiratory infections * Elevated liver enzymes ### Serious Side Effects Leflunomide can cause serious adverse reactions, including: * **Liver injury** * Severe infection * Serious blood disorders * Severe skin reactions * Lung problems/interstitial lung disease * Peripheral neuropathy * Severe allergic reactions * Increased blood pressure Seek urgent medical attention for: * Yellowing of the skin or eyes * Dark urine * Severe abdominal pain * Unexplained bruising or bleeding * Persistent fever * Severe cough or difficulty breathing * Widespread blistering or peeling skin * Facial or throat swelling * Severe weakness or numbness --- ## Precautions & Warnings ### Liver Toxicity Leflunomide can cause **serious liver injury**. Tell your doctor if you have: * Liver disease * A history of hepatitis * Abnormal liver function tests * Heavy alcohol consumption Liver function tests are generally required before and during treatment. ### Blood Disorders Leflunomide can reduce blood-cell counts in some patients. Your doctor may monitor: * Complete blood count * White blood cells * Platelets * Hemoglobin ### Infection Risk Because leflunomide suppresses immune activity, it can increase susceptibility to infections. Contact your doctor if you develop: * Persistent fever * Severe sore throat * Persistent cough * Unusual infections * Other signs of serious infection ### Pregnancy **Leflunomide can cause serious fetal harm.** It should **not be used during pregnancy** unless specifically directed under exceptional specialist circumstances. Women who could become pregnant generally require appropriate contraception during treatment and may need a drug-elimination procedure before attempting conception. Men planning to father a child should also discuss leflunomide with their healthcare professional because the active metabolite can persist in the body. ### Vaccinations Discuss vaccination with your doctor before treatment. Certain **live vaccines** may not be appropriate during leflunomide treatment. ### Blood Pressure Leflunomide can increase blood pressure. Blood pressure should be monitored during treatment. ### Lung Problems Rarely, leflunomide can cause serious lung problems. Tell your doctor if you develop: * New or worsening cough * Shortness of breath * Difficulty breathing * Unexplained fever ### Neuropathy Leflunomide may rarely cause peripheral neuropathy, characterized by: * Tingling * Numbness * Burning sensations * Weakness Report these symptoms promptly. --- ## Drug Interactions ### Methotrexate Leflunomide may be combined with methotrexate in selected patients, but the combination can increase the risk of **liver toxicity and blood abnormalities**. Close medical monitoring is required. ### Other Immunosuppressants Combining leflunomide with other immunosuppressive medicines may increase the risk of: * Serious infections * Blood disorders * Liver toxicity ### Hepatotoxic Medicines Medicines that can affect the liver may increase the risk of liver injury when combined with leflunomide. Tell your doctor about all medicines that may affect liver function. ### Rifampicin Rifampicin can increase levels of the active metabolite of leflunomide and may increase adverse effects. ### Warfarin Leflunomide may affect the response to warfarin. Patients taking warfarin may require closer monitoring of **INR**. ### Certain Cholesterol Medicines Some medicines that affect liver metabolism may interact with leflunomide. ### Alcohol Alcohol may increase the risk of **liver damage**. Avoid or minimize alcohol according to your healthcare professional's advice. ### Other Medicines Always tell your doctor or pharmacist about: * Prescription medicines * OTC medicines * Vitamins * Herbal supplements * Other arthritis medicines before starting leflunomide. --- ## Storage Information * Store at **room temperature according to the manufacturer's instructions**. * Keep tablets in their original packaging. * Protect from excessive heat, moisture, and direct sunlight. * Keep the container tightly closed. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the medicine appears deteriorated. --- ## Prescription Status **Leflunomide 20 mg is a prescription-only medicine.** It should be prescribed and monitored by a qualified healthcare professional, often a rheumatologist or physician experienced in treating inflammatory arthritis.
