General Description of Arava:
Arava is a prescription medication used to treat rheumatoid arthritis by reducing inflammation and slowing the progression of joint damage. It belongs to a class of medications called disease-modifying antirheumatic drugs (DMARDs).
DMARDs are drugs that work to arrest the autoimmune response that leads to inflammation and tissue damage in rheumatoid arthritis. Arava specifically inhibits the enzyme dihydroorotate dehydrogenase, which is involved in the production of DNA and cell division in activated T lymphocytes that contribute to the inflammation in arthritis.
According to the Arava website, the active ingredient in Arava is leflunomide. It is available in tablet form and is usually taken once daily.
Benefits of Arava:
- Reduces inflammation
- Slows progression of joint damage
- Improves overall joint function
Side Effects of Arava:
Common side effects of Arava may include:
- Diarrhea
- Nausea
- Hair loss
- High blood pressure
Precautions When Taking Arava:
It is important to consult with a healthcare provider before starting Arava, as it can interact with other medications. Additionally, Arava should not be taken by pregnant women or those planning to become pregnant due to potential risks to the fetus.
According to a study published in the National Library of Medicine, Arava has been shown to be effective in reducing disease activity and improving physical function in patients with rheumatoid arthritis.

How Does Arava Work?
Arava, also known by its generic name leflunomide, works by reducing inflammation and slowing down the progression of joint damage in patients with rheumatoid arthritis.
Mechanism of Action:
- Arava inhibits dihydroorotate dehydrogenase, an enzyme involved in the production of DNA and RNA in immune cells, thereby reducing their proliferation.
- It also suppresses the proliferation of T-lymphocytes, which are involved in the inflammatory response in rheumatoid arthritis.
Starting Arava Treatment
Before starting Arava, your healthcare provider will perform several tests to determine if it is a suitable option for you based on your medical history and current health status. These tests may include:
- Baseline liver function tests to monitor liver enzymes.
- Tuberculosis screening as Arava can potentially reactivate latent tuberculosis infections.
- Monitoring blood pressure and weight to assess potential side effects.
Once your healthcare provider has determined that Arava is appropriate for you, they will start you on the medication at a specific dose based on your individual needs.
Potential Side Effects of Arava
Common side effects of Arava may include:
- Diarrhea
- Nausea
- Abdominal pain
- Hair loss
If you experience severe side effects such as liver toxicity or lung problems, contact your healthcare provider immediately.
Monitoring while on Arava
Your healthcare provider will regularly monitor your blood tests while you are taking Arava to check for:
- Changes in liver function
- Low blood cell counts
- Signs of infection
These regular check-ups are important to ensure your safety and adjust your treatment plan if needed.

3. How does Arava work?
Arava works by targeting the immune system to reduce inflammation in the joints. The active ingredient in Arava is leflunomide, which inhibits an enzyme called dihydroorotate dehydrogenase. This enzyme plays a crucial role in the production of DNA and RNA in rapidly dividing cells, including cells of the immune system. By blocking this enzyme, Arava helps to reduce the activity of the immune system and the production of inflammatory cells.
According to a study published in the Journal of Clinical Rheumatology, Arava has been shown to significantly decrease disease activity in patients with rheumatoid arthritis.
Furthermore, Arava is believed to slow down the progression of joint damage by reducing the inflammatory response that leads to cartilage and bone destruction in rheumatoid arthritis.
3.1 Side effects of Arava
While Arava is an effective treatment for rheumatoid arthritis, it may come with certain side effects. Common side effects of Arava include nausea, diarrhea, headache, and hair loss. In some cases, it may also cause liver problems, such as elevated liver enzymes. It is important to monitor liver function through regular blood tests while taking Arava.
3.2 Dosage and administration
The typical starting dose of Arava for rheumatoid arthritis is 100 mg once daily for the first three days, followed by 20 mg once daily thereafter. The dosage may be adjusted by a healthcare provider based on the individual’s response to treatment and any side effects experienced. It is important to take Arava exactly as prescribed to achieve the best results.
3.3 Cost of Arava
The cost of Arava can vary depending on the dosage strength, quantity, and location. On average, a one-month supply of Arava 20 mg tablets can range from $100 to $300. Discounts and insurance coverage may help lower the out-of-pocket cost for some individuals.
3.4 User experiences with Arava
Users of Arava have reported both positive and negative experiences with the medication. Some users have praised Arava for effectively reducing joint pain and inflammation, improving their quality of life. However, others have mentioned experiencing side effects such as gastrointestinal issues and hair thinning. It is essential for individuals to discuss any concerns or side effects with their healthcare provider.
In conclusion, Arava is a valuable medication for managing rheumatoid arthritis by targeting inflammation and slowing joint damage. It is important to weigh the benefits and potential side effects of Arava in consultation with a healthcare provider to determine the most suitable treatment approach.
