3. Biologic Treatments
What it is: Biologic drugs target the immune response that causes inflammation.
How it works: Biologics block immune cells that are involved in psoriasis. These drugs are given by a shot or by an IV infusion.
Biologic drugs include:
- Ustekinumab (Stelara). This drug blocks cytokines in the body called interleukin-12 and interleukin-23, which are thought to promote the increased growth rate of skin cells and inflammation from psoriasis.
- Tumor necrosis factor-alpha blockers, including adalimumab (Humira), etanercept ( Enbrel), golimumab (Simponi), and infliximab ( Remicade). These drugs block a chemical messenger of the immune system called TNF-alpha. People with psoriasis have too much of this substance, which causes inflammation.
You may need to be screened for tuberculosis while taking a biologic drug. You may also need to have regular blood tests to check your number of immune blood cells.
