TNF Blockers: Uses, Common Brands, and Safety Info

TNF blockers are a class of medications used to treat autoimmune diseases by inhibiting tumor necrosis factor (TNF). They help reduce inflammation in conditions like rheumatoid arthritis, psoriasis, ankylosing spondylitis, and inflammatory bowel diseases. Common brands include Humira, Enbrel, and Remicade. Side effects may include injection site reactions, headaches, and higher susceptibility to infections. Use during pregnancy and breastfeeding is generally not recommended.

TNF Blockers

TNF blockers, also known as tumor necrosis factor blockers, are a class of medications that work by targeting and inhibiting the action of tumor necrosis factor (TNF). TNF is a protein that plays a key role in the inflammatory process, and excessive TNF production has been linked to a variety of chronic autoimmune diseases, such as rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, and ulcerative colitis.


TNF blockers are primarily used to treat autoimmune diseases characterized by excessive TNF production. By inhibiting the action of TNF, these medications help reduce inflammation, alleviate symptoms, and slow down the progression of the disease.

Some common uses of TNF blockers include:

  • Treating rheumatoid arthritis: TNF blockers can relieve pain, reduce joint stiffness, and prevent joint damage in individuals with this chronic autoimmune condition.

  • Managing psoriasis and psoriatic arthritis: TNF blockers help control the skin inflammation associated with psoriasis and reduce joint pain and swelling in psoriatic arthritis.

  • Alleviating symptoms of ankylosing spondylitis: TNF blockers can improve mobility, reduce pain and stiffness in the spine and joints affected by this type of arthritis.

  • Treating inflammatory bowel diseases: TNF blockers are commonly used to manage symptoms of Crohn's disease and ulcerative colitis, such as abdominal pain, diarrhea, and rectal bleeding.

Common Brands

Several TNF blockers are available on the market, and they are often prescribed based on the specific condition being treated:

  • Adalimumab (Humira)

  • Etanercept (Enbrel)

  • Infliximab (Remicade)

  • certolizumab (Cimzia)

  • golimumab (Simponi)


Like any medication, TNF blockers come with potential risks and side effects. It is important to consult with a healthcare professional before starting this type of treatment, as they can help weigh the potential benefits against the risks.

Some common side effects of TNF blockers include:

  • Injection site reactions

  • Headaches

  • Upper respiratory infections

  • Nausea

  • Abdominal pain

In addition, TNF blockers can weaken the immune system, making individuals more susceptible to infections. Therefore, necessary precautions should be taken to reduce the risk of infections, and any signs of infection should be reported to a healthcare professional immediately.

Individuals who have a history of certain infections, including tuberculosis, should exercise caution when considering TNF blocker therapy.

Furthermore, TNF blockers are generally not recommended during pregnancy or while breastfeeding, as their effects on the developing fetus or newborn are not yet fully understood. It is essential to discuss the potential risks and benefits of this medication with a healthcare professional in such situations.

Overall, TNF blockers have shown to be effective in managing and improving the quality of life for individuals with certain autoimmune diseases. However, it is crucial to follow the prescribed dosage, adhere to regular check-ups, and report any concerning symptoms or side effects to a healthcare professional.
