How does Humira work?
Humira is a medicine known as a tumor necrosis factor (TNF) inhibitor. TNF is a protein made by your immune system. In people with certain autoimmune diseases like RA, the immune system makes too much TNF. This leads to RA symptoms like joint pain, stiffness, and swelling.1
Humira works by targeting and sticking to the extra TNF in your body. This helps reduce RA symptoms and prevent further joint damage.1
What are the possible side effects?
The most common side effects of Humira include:1
- Redness, itching, pain, or swelling at the site of injection
- Upper respiratory infection, including sinus infection
Humira has a boxed warning, the strictest warning from the US Food and Drug Administration (FDA). It has this warning because it may cause serious side effects, including:1
- Serious infections, such as tuberculosis (TB) and sepsis, that can lead to hospitalization or death
- Increased risk of certain cancers, especially in children and teens
Your doctor will test you for TB before you start Humira. Your doctor will also closely monitor you for signs and symptoms of TB during treatment with Humira.1
Do not start taking Humira if you have any type of infection unless your doctor tells you to. Contact your doctor right away if you have any signs of an infection, such as:1
