Arava (Leflunomide) – Patient-Friendly Guide (Australia)

Arava is a medicine containing leflunomide, used to treat certain inflammatory conditions, particularly rheumatoid arthritis and psoriatic arthritis. It helps reduce inflammation, slow disease progression, and improve long-term joint function.

This page explains how Arava works, how it’s taken, what to expect, possible side effects, and important safety information, including interactions with alcohol and other medicines. It also covers practical tips, alternative treatment options, and Australia-specific availability and guidance.

Basic product information

Important: Leflunomide can remain in the body for a long time. If stopping is required (for example, due to side effects or pregnancy planning), a specialist-directed “washout” procedure may be needed to clear the medicine.

How Arava works (mechanism of action)

Leflunomide is a DMARD. After you take it, your body converts it into an active form that affects immune signalling involved in inflammation. In simple terms, it can:

• Reduce inflammatory activity in the joints and surrounding tissues
• Slow immune-driven damage that occurs in chronic inflammatory arthritis
• Help improve symptoms such as pain, swelling, and morning stiffness

It does not work like pain-relieving medicines (such as paracetamol or anti-inflammatory painkillers). Instead, it aims to change the underlying course of the disease over time.

Pharmacokinetics: how the body processes leflunomide

Understanding pharmacokinetics can help you set expectations about when benefits appear and why monitoring is important. Key points include:

• Conversion to active metabolite: Leflunomide is converted in the body to an active metabolite (teriflunomide).
• Long-lasting effect: The active metabolite can persist in the body for weeks to months. This is one reason stopping the medication may require an additional “washout” step to lower levels rapidly when necessary.
• Steady concentrations: With regular dosing, levels build gradually. Many people start noticing improvements after several weeks, with fuller benefit taking longer.
• Elimination: The active metabolite is eliminated slowly, primarily via the bile/intestines, and to a lesser extent through the kidneys.

Because leflunomide can remain in the body, it’s crucial to follow your clinician’s advice about what to do if you miss doses, stop treatment, or plan pregnancy.

Typical use in Australia

Arava is commonly used as a long-term controller for inflammatory arthritis. It may be used when:

• Symptoms and inflammation persist despite other approaches
• Your clinician recommends a conventional DMARD
• A steroid-sparing strategy is considered (where appropriate)

Treatment plans can vary. Some people take leflunomide alone, while others may use it alongside other medicines (such as folic acid supplementation, anti-inflammatory medicines, or other DMARDs), depending on individual needs.

Indications (what Arava is used for)

In general, leflunomide is indicated for:

• Rheumatoid arthritis (RA)
• Active psoriatic arthritis (in selected patients)
• In some regions and under specialist assessment, it may also be considered for other inflammatory arthritides. Your local product information should be followed for your specific circumstances.

If you are unsure whether Arava is appropriate for your condition, ask your treating healthcare professional.

How and when to take Arava

Most regimens are taken once daily. Timing guidance can help you avoid missed doses and reduce stomach upset. Always use the dosing schedule provided to you.

Starting and dose adjustments

Common approaches include a loading phase in some patients, followed by a maintenance dose. Not everyone uses a loading dose, and changes may be made based on response and blood tests.

If you miss a dose, do not take extra to “catch up” unless your clinician advises. Instead, take the next dose at the usual time.

Timing with daily routine

• Choose a consistent time: many people take it at the same time each day.
• Swallow whole with water: follow tablet instructions from the packaging.
• Be patient: improvement often takes time (commonly several weeks).

Dosing (general information)

Dosing must be personalised. Below is general dosing information to help you understand typical regimens. Your healthcare team may adjust it based on disease severity, blood test results, tolerance, and other medicines.

Key point: Your exact tablet strength, start date, and ongoing daily dose should match the plan provided by your clinician. Always check your medicine label or the instructions you were given.

Food interactions: can you take Arava with meals?

Arava tablets can generally be taken with or without food. For many people, taking it with food can reduce gastrointestinal discomfort.

• If you experience nausea or stomach upset, try taking it with a meal or a snack.
• Stay consistent with your routine. Consistency may help with tolerability.

There are no widely known specific foods that must be avoided solely because of leflunomide. However, always consider interactions with any other medicines or supplements you’re taking.

Alcohol interactions (important)

Leflunomide can affect the liver. For this reason, alcohol should be used cautiously or avoided unless your clinician advises otherwise. Combining alcohol with medications that can stress the liver may increase the risk of liver injury.

• Limit alcohol: avoid binge drinking and keep intake low.
• Know the warning signs: seek medical advice promptly for symptoms such as yellowing of the skin/eyes, dark urine, persistent nausea/vomiting, severe fatigue, or upper abdominal pain.
• Discuss your history: if you have fatty liver disease, hepatitis, or prior abnormal liver tests, talk to your healthcare professional before drinking.

If you’re unsure how much (if any) alcohol is safe for you, ask your clinician or pharmacist. They can tailor advice based on your liver function tests and overall risk factors.

Medicine interactions (including common concerns)

Drug interactions matter because leflunomide can influence liver enzymes and because other medicines may also affect blood counts or the liver. Inform your healthcare professional about all medicines, including over-the-counter products and herbal supplements.

Common categories to review

• Other DMARDs or immunosuppressants: combining can increase infection risk and may increase side effects.
• Medicines that affect the liver: combining may increase liver risk (for example, certain antibiotics or antifungals, some anti-seizure medicines, and some herbal products).
• Blood-thinning medicines (anticoagulants): interaction risk may exist; close monitoring may be needed.
• Live vaccines: immunosuppression may make live vaccines unsuitable; speak to your clinician.
• Cholestyramine or activated charcoal: these can speed up elimination of the active metabolite in some scenarios, such as planned stopping.

Always check with a pharmacist or clinician if you start a new medicine, including antibiotics or antifungal treatments. Even “short courses” can matter.

Safety profile: what to watch for

Like all medicines, Arava can cause side effects. Many people tolerate it well, but monitoring is essential. The most important safety considerations include:

Liver effects

• What may happen: elevated liver enzymes and, rarely, more serious liver injury.
• What to do: attend regular blood test monitoring and seek urgent advice for symptoms of liver problems.

Blood count changes

• What may happen: decreased white blood cells or platelets in some people.
• What to do: follow blood test schedules and report unusual bruising, bleeding, fever, or sore throat.

Infections

• What may happen: because it affects immune activity, infections may occur more easily.
• What to do: contact your clinician early if you develop fever, persistent cough, painful urination, or signs of infection.

Skin reactions and hypersensitivity

• What may happen: rash and, rarely, serious skin reactions.
• What to do: seek immediate medical attention for severe rash, blistering, or skin peeling.

Nerve or lung symptoms (less common)

• Report new breathing difficulty, persistent shortness of breath, or unexplained cough.
• Seek advice for unusual numbness, tingling, or weakness.

Pregnancy and fertility concerns (very important)

Leflunomide is not suitable during pregnancy because it may harm an unborn baby. If pregnancy is planned, discuss stopping and washout timing with your healthcare professional well in advance.

Women who could become pregnant and people of reproductive potential should use reliable contraception while taking leflunomide, and follow guidance for clearance before trying to conceive.

Practical use tips for everyday life

• Don’t skip monitoring: follow scheduled blood tests (commonly including liver function and full blood count).
• Keep a medicine list: carry an up-to-date list of your medicines and supplements.
• Watch for warning signs: fever, unusual infections, yellowing of skin/eyes, dark urine, severe fatigue, persistent nausea, or significant bruising should prompt medical advice.
• Plan around travel: ensure you have enough tablets before trips and consider time zones for consistent dosing.
• Manage missed doses carefully: if you’re unsure what to do, contact your pharmacist for guidance.
• Skin care matters: for people who notice rashes, avoid new skin products and report changes promptly.

What to expect: when benefits may start

DMARDs like leflunomide can take time to work. Many patients notice early improvements within weeks, but full benefit can take longer. If you’re switching from another DMARD or adding therapies, your clinician may plan the transition carefully.

It’s normal to have good and bad days early on. Continue taking the medicine as directed and attend monitoring appointments to ensure safety.

Stopping or changing Arava: why guidance is essential

Because leflunomide’s active metabolite can stay in the body for a long time, stopping treatment may not mean levels drop quickly. For urgent reasons to clear the drug (for example, pregnancy planning or certain safety concerns), a structured elimination procedure may be recommended.

Do not stop or restart Arava based solely on symptoms without speaking to your healthcare professional.

Alternative options

If Arava isn’t suitable, or if side effects or inadequate response occur, clinicians may consider other treatments. Options vary by diagnosis, disease severity, and individual risk factors.

Conventional DMARD alternatives

• Methotrexate
• Sulfasalazine
• Hydroxychloroquine

Biologic DMARDs and targeted therapies

• Biologic agents (e.g., tumour necrosis factor inhibitors or other targeted biologics)
• Targeted synthetic DMARDs (e.g., some JAK inhibitors)

Your clinician may recommend these if conventional DMARDs are ineffective or not tolerated. The safest choice depends on your medical history, infection risk, monitoring results, and preferences.
