Adalimumab belongs to a class of medicines called biological disease modifying antirheumatic drugs (biological DMARDs or bDMARDs). Specifically, it is a Tumour Necrosis Factor (TNF) inhibitor. bDMARDs have now been given to over a million people worldwide since their first use in the late 1990s.
These medicines block substances called cytokines. These cytokines are found in excessive amounts in the blood and joints of people with conditions such as rheumatoid arthritis, psoriatic arthritis, juvenile arthritis and ankylosing spondylitis.
They cause inflammation, which results in symptoms of pain, joint swelling and stiffness, and can lead to joint damage. They also cause eye inflammation in people who have uveitis.
By blocking the cytokine called TNF, adalimumab lessens inflammation, pain symptoms and helps stop further joint damage.
Adalimumab can help people with inflammatory arthritis live longer with a better quality of life. Studies show that patients who take adalimumab have a lower risk of death and fewer flares. Many patients with inflammatory arthritis experience reduced pain, swelling, and stiffness from taking adalimumab. It helps to slow or stop disease progression and prevent joint or organ damage. This can enhance mobility and reduce disability. Adalimumab usually takes several weeks to take effect. It is important to continue taking the medicine as prescribed to see full benefits.
If you stop or delay your adalimumab treatment, you may worsen again. Continue your treatment, unless told by your rheumatologist to stop or unless side effects occur (see Side effects). If you stop adalimumab for any reason, you must contact your rheumatologist.
Failure to do so may mean that your treatment may no longer be funded.
Adalimumab is injected under the skin of the abdomen or thigh. It comes in a pen or a syringe injection.
It can be injected by your doctor, nurse, carer or by you. If injecting yourself, be sure to follow the detailed instructions carefully to ensure the best response. It is important to change where you inject each time.
The usual dose for adults with arthritis is 40mg once every two weeks.
Adalimumab may be used with other arthritis medicines including:
Adalimumab cannot be used with other bDMARDs. There are separate information sheets for the medicines mentioned above.
You might experience side effects with your treatment. Contact your rheumatologist if you have any concerns about possible side effects. Many side effects go away when you stop taking adalimumab.
