Leflunomide
About Leflunomide
Leflunomide is a prescription medication primarily used to treat active rheumatoid arthritis in adults. It belongs to a class of medicines known as disease-modifying antirheumatic drugs (DMARDs), which help control swelling, pain, and stiffness in your joints. By managing these chronic symptoms, this medicine helps prevent long-term joint damage and assists you in maintaining your daily physical function.
To get the most benefit, you must take Leflunomide consistently every day, exactly as prescribed by your healthcare provider. You can take this tablet with or without food, but taking it at the same time each day will help you build a reliable routine. Making healthy adjustments, such as eating a balanced diet and doing gentle, joint-friendly exercises, can support your treatment outcomes.
While taking Leflunomide, some people may experience mild side effects like diarrhoea, nausea, or temporary hair thinning. However, you must contact your doctor immediately if you notice serious symptoms such as yellowing of your eyes or skin, dark urine, or unusual tiredness, as these could indicate liver damage.
Do not take this if you are pregnant, planning to become pregnant, or breastfeeding, as this medicine can cause severe harm to an unborn baby. Before starting Leflunomide, talk to your doctor if you have a history of liver disease, severe infections, kidney problems, or a weakened immune system.
This medicine can interact with certain other drugs, alcohol, and live vaccinations, which may increase your risk of liver issues or serious infections. Because of these risks, elderly individuals and people with pre-existing medical conditions should talk to their doctor or pharmacist before starting treatment to ensure it is safe for them.
Uses of Leflunomide
Medicinal Benefits
Leflunomide helps control inflammation and slow disease progression in certain autoimmune joint disorders. Its benefits may include:
- Slowing Joint Damage: Unlike simple pain relievers that only mask symptoms, Leflunomide works deep within the immune system to slow down the progression of joint destruction, helping you preserve your joint health over the long term.
- Improved Daily Mobility: By targeting chronic swelling and stiffness, this medicine makes daily physical activities, such as walking, bending, and reaching, much easier and more comfortable.
- Long-lasting Inflammatory Relief: Regular use helps stabilise your body's overactive immune response, leading to fewer painful flare-ups and a more consistent level of physical comfort throughout your day.

To use Leflunomide safely and effectively, follow these instructions:
- Swallow the tablet whole with a full glass of water. Do not crush, chew, or break the tablet, as this can affect how the medicine is absorbed.

- Try to take your dose at the same time every day to maintain a steady level of the medication in your system.

FAQs
Leflunomide is used to relieve symptoms of rheumatoid arthritis and psoriatic arthritis.
Leflunomide is a disease-modifying antirheumatic drug (DMARD) which stops the DNA (genetic material) of the provoked immune system cells required for their survival. It thereby helps in treating inflammation, redness, and swelling at the damaged site (especially joints).
Leflunomide may cause diarrhoea. Drink plenty of fluids and eat non-spicy food if you experience diarrhoea. If you find blood in stools (tarry stools) or if you experience severe diarrhoea, consult your doctor. Do not take anti-diarrheal medicine on your own.
Inform your doctor if you have liver disease, kidney disease, a weak immune system and serious infections like pneumonia, or tuberculosis (TB).
The best time to take leflunomide is usually in the morning, with food, to help minimize stomach upset. However, following your doctor's specific instructions for taking leflunomide is essential, as the optimal timing may vary depending on your needs and health status.
Leflunomide is not a steroid. It contains leflunomide, which is an immunomodulatory medication used to treat rheumatoid arthritis and psoriatic arthritis. Leflunomide works by reducing inflammation and slowing the progression of the disease.
Leflunomide may cause weight loss as a side effect. This weight loss is usually insignificant and may be due to a loss of appetite. If you experience significant weight loss, it is essential to consult your doctor.

Regular check-ups make you feel confident and safe while managing your condition with leflunomide.
It can take anywhere from 4 to 12 weeks to notice a significant improvement in your joint pain and swelling.

Talk to your doctor if you do not notice any changes after several weeks.
No, you should completely avoid alcohol while taking this medicine. Both alcohol and the active drug in Leflunomide are processed by the liver, and combining them can cause severe, potentially permanent liver damage. Talk to your doctor if you have concerns about avoiding alcohol.
