About Arava
Generic Arava (Leflunomide) is an oral disease-modifying antirheumatic drug (DMARD) approved in Australia for the treatment of moderate to severe rheumatoid arthritis and other autoimmune conditions. By inhibiting a key enzyme in pyrimidine synthesis, it reduces the proliferation of activated lymphocytes that drive joint inflammation. While the branded name Arava is widely recognised, the medication is essentially a generic formulation of leflunomide, offering a cost-effective alternative to more expensive biologics. Patients often seek to buy Arava online for convenience, especially when traditional pharmacies have limited stock. Understanding how this drug works, its therapeutic niche, and practical tips for safe use can help you make an informed decision about incorporating it into your arthritis management plan.
What is Generic Arava (Leflunomide)?
Generic Arava (Leflunomide) belongs to the class of immunosuppressive DMARDs. It received TGA approval in 1999 and is marketed in tablet form (10 mg and 20 mg strengths) for adults with rheumatoid arthritis who have had an inadequate response to conventional therapy. The product is manufactured by several international companies, but the brand name remains Arava, distinguishing it from other leflunomide formulations. In Australia, it is prescription-only and listed on the Pharmaceutical Benefits Scheme (PBS) for eligible patients, which helps reduce out-of-pocket costs.
How Arava Works
Arava’s active ingredient, leflunomide, is a pro-drug that is rapidly converted to its pharmacologically active metabolite, A77 1726. This metabolite inhibits dihydroorotate dehydrogenase (DHODH), a mitochondrial enzyme essential for de novo synthesis of pyrimidines. Lymphocytes, especially activated T and B cells, rely heavily on this pathway for DNA replication and cytokine production. By blocking DHODH, leflunomide reduces the pool of uridine nucleotides, leading to cell-cycle arrest in the G1 phase and limiting the expansion of autoreactive immune cells.
Pharmacokinetically, A77 1726 reaches steady-state concentrations after about 3 weeks of daily dosing, which aligns with the observed therapeutic onset. The metabolite has a long half-life (≈2 weeks), allowing once-daily dosing and contributing to sustained immunosuppression even after the tablet is stopped. Metabolism occurs primarily via hepatic pathways (CYP1A2, CYP2C19), and the drug is excreted renally as unchanged metabolite and minor glucuronide conjugates.
Why Arava is Used for Arthritis and Immunosuppressant Conditions
- Rheumatoid arthritis (RA) - The inhibition of DHODH curtails the proliferation of synovial fibroblasts and inflammatory lymphocytes, reducing joint swelling, pain, and radiographic progression. Clinical trials (e.g., the LEF-1 and LEF-2 studies) demonstrated significant ACR20 response rates compared with placebo, supporting its role as a first-line DMARD when methotrexate is contraindicated or poorly tolerated.
- Psoriatic arthritis - Similar pathogenic mechanisms involving T-cell activation make leflunomide effective in controlling skin lesions and peripheral joint disease. Real-world registries note comparable efficacy to biologic agents for patients with mild-to-moderate disease.
- Ankylosing spondylitis - Although not formally approved for this indication in Australia, leflunomide’s ability to dampen cytokine release (especially IL-17 and IL-23 pathways) provides clinical benefit in off-label use, particularly when NSAIDs fail.
- Systemic lupus erythematosus (SLE) - renal involvement - Small pilot studies have reported reduced proteinuria and serological activity when leflunomide is added to standard therapy, reflecting its broad immunosuppressive profile.
- Combination therapy - Arava is often paired with low-dose corticosteroids or biologics to achieve faster disease control, leveraging its oral convenience while minimizing steroid exposure.
In treatment guidelines, leflunomide is positioned as a viable alternative to methotrexate, especially for patients with hepatic concerns or intolerance to injectable agents. Its oral route and once-daily dosing make it attractive for those seeking a convenient regimen.
Off-Label and Investigational Uses of Arava
Research has explored leflunomide in several off-label contexts. Small randomized controlled trials suggest a modest benefit in preventing acute rejection after renal transplantation when used alongside standard immunosuppressants. Additionally, case-series have evaluated its efficacy in multiple sclerosis, noting reduced relapse rates, though robust evidence remains lacking. In oncology, early-phase studies investigated leflunomide’s anti-angiogenic properties for certain solid tumors, but results were inconclusive.
Off-label use should only be considered under the supervision of a qualified healthcare provider, as safety data are limited and dosing may differ from arthritis protocols.
Is Arava Right for You?
Arava is most appropriate for adults with confirmed rheumatoid arthritis who have not achieved adequate control with non-biologic DMARDs or who cannot tolerate methotrexate. It is also considered for psoriatic arthritis and, in some cases, for ankylosing spondylitis when other options fail. Special populations require careful assessment:
- Elderly patients - Age-related renal decline may prolong metabolite clearance; dose adjustments or therapeutic drug monitoring are advisable.
- Pregnancy and lactation - Leflunomide is teratogenic; women of child-bearing potential must undergo an accelerated elimination procedure (cholestyramine or activated charcoal) before conception.
- Hepatic impairment - Since leflunomide is hepatically metabolised, baseline liver function tests and periodic monitoring are essential.
- Renal insufficiency - Dose reduction to 10 mg daily is recommended when eGFR falls below 30 mL/min/1.73 m².
Contraindications such as severe infection, hypersensitivity, or active hepatitis should be identified before initiating therapy. Discuss with your rheumatologist to confirm that Arava aligns with your disease activity and comorbidities.
Taking Arava Effectively
- Timing - Take the tablet with or without food once daily, preferably at the same time each day to maintain stable plasma levels.
- Loading dose - Some clinicians prescribe an initial 100 mg loading dose for two consecutive days to achieve therapeutic concentrations faster; however, this is not universal in Australian practice.
- Missed dose - If a dose is missed and it’s within 12 hours of the usual time, take it as soon as remembered. Skip it if it’s later, and resume the regular schedule-doubling up is unnecessary and may increase toxicity.
- Drug interactions - Avoid concomitant use of strong CYP1A2 inhibitors (e.g., fluvoxamine) as they raise A77 1726 levels. Anticonvulsants that induce CYP enzymes may reduce efficacy.
- Travel considerations - Carry a copy of your prescription and a brief medication summary; leflunomide’s long half-life means you do not need to adjust dosing for time-zone changes, but keep tablets protected from extreme temperatures.
Adhering to these practical tips maximises therapeutic benefit while minimizing adverse events.
Understanding Side Effects and How to Manage Them
Common adverse reactions-diarrhea, alopecia, and elevated liver enzymes-stem from the drug’s impact on rapidly dividing cells and hepatic metabolism. Strategies to mitigate them include:
- Gastrointestinal upset - Take the tablet with a full glass of water and a light snack; if diarrhea persists, a short course of loperamide may help.
- Hair loss - Typically reversible upon dose reduction or discontinuation; consider using gentle hair care products and a balanced diet rich in biotin.
- Hepatotoxicity - Baseline liver function tests are mandatory, followed by monitoring every 4-8 weeks during the first six months. If transaminases rise above three times the upper limit of normal, hold the medication and reassess.
Serious complications such as severe infections, pulmonary toxicity, or hematologic abnormalities are rare but require immediate medical attention. Patients should be counseled to report fever, persistent cough, or unexplained bruising without delay.

Frequently Asked Questions
-
How long does it take for Arava to start working? Clinical improvement is usually evident after 4-6 weeks of consistent dosing, with maximal benefit occurring around 12 weeks as steady-state metabolite levels are reached.
-
Can I take Arava together with methotrexate? Combination therapy is common in rheumatology and can provide synergistic disease control. However, both drugs share hepatotoxic potential, so liver function must be monitored closely.
-
Is it safe to receive a flu vaccine while on Arava? Yes. Inactivated vaccines, including the seasonal influenza shot, are recommended for patients on immunosuppressants. Live vaccines should be avoided unless the medication has been discontinued for an appropriate wash-out period.
-
What should I do if I become pregnant while taking Arava? Discontinue immediately and initiate the accelerated elimination protocol (cholestyramine 4 g three times daily for 11 days). Consult a specialist obstetrician for further guidance.
-
Does alcohol increase the risk of side effects? Alcohol can exacerbate liver enzyme elevations, so moderating intake is advisable. Heavy drinking should be avoided during treatment.
-
How does Arava compare to biologic agents? While biologics target specific cytokines (e.g., TNF-α, IL-6), Arava provides a broad immunosuppressive effect through DHODH inhibition. It is less costly and oral, but may be less potent in severe refractory disease, where biologics are preferred.
-
Can I switch from another DMARD to Arava without a wash-out period? A short overlap of up to two weeks is generally acceptable, but a physician may recommend a brief wash-out to minimize additive toxicity, especially with hepatotoxic agents.
-
What monitoring is required after starting Arava? Baseline CBC, liver function tests, and renal function are mandatory. Repeat liver enzymes every 4-8 weeks for the first six months, then quarterly. CBC is checked similarly to detect rare neutropenia.
-
Is generic Arava (Leflunomide) bioequivalent to the branded product? Yes. Regulatory agencies require demonstrated bioequivalence, meaning the generic delivers the same amount of active metabolite A77 1726 as the reference brand.
-
Can I store Arava in the bathroom cabinet? Store tablets at room temperature away from moisture and direct sunlight. A bathroom cabinet may be too humid; a kitchen drawer or bedroom nightstand is preferable.
