The medication you are using when you take Humira is a tumor necrosis factor (TNF) blocker. This type of drug is sometimes simply referred to as an anti-TNF drug. It targets a substance within the body known as TNF that is produced by the immune system. It can lead to inflammation and is often associated with the discomfort and other symptoms you experience as a result of rheumatoid arthritis. When you use an anti-TNF drug such as Humira, it helps to reduce the inflammation, pain and loss of range of movement. At the same time, however, it also affects the function of the immune system which can lead to problems.
One of the primary things to be concerned about when using an anti-TNF drug is the possibility for infection. Since you are limiting the effectiveness of the immune system, serious or sometimes life-threatening infections can occur. Those infections might include tuberculosis and it can also increase your risk for squamous cell skin cancer and basal cell skin cancer. You should watch for any unusual side effects when taking the medication and keep your doctor informed of any problems you are experiencing.
Dr. Lavery may prescribe Humira because he feels it would be the best choice for you and your condition. Many people have taken it and experience the benefits of reduced pain and inflammation. As long as you watch for side effects and take the medication as directed it is less likely for you to experience any problems with it.
