TREMFYA

What is this medication? Tremfya is a prescription brand-name medication known generically as guselkumab. It is primarily used to treat adults living with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. Additionally, it is approved for the treatment of adults with active psoriatic arthritis. The medication works by targeting a specific protein in the body called interleukin-23, which is involved in the inflammatory response that causes skin cells to overproduce and joints to become swollen.

This medication is administered via an injection under the skin, typically starting with two initial doses and then continuing with maintenance doses every eight weeks. By blocking the action of interleukin-23, Tremfya helps to clear skin plaques and reduce the joint pain and stiffness associated with psoriatic arthritis. Because it affects the immune system, healthcare providers usually screen patients for infections like tuberculosis before starting treatment and monitor for potential side effects during the course of therapy.
