How does this medication work? What will it do for me?

Tildrakizumab belongs to the class of medications called immunomodulators. It is used to treat adults with moderate-to-severe plaque psoriasis for whom treatment with systemic therapy (medications that work from within the body) or phototherapy is appropriate.

For people with plaque psoriasis, the body overproduces a protein called interleukin-23 (IL-23).  Increased levels of this protein cause inflammation which can result in itching, pain, and scaling skin. Tildrakizumab recognizes this protein and blocks its action, reducing the symptoms of plaque psoriasis.

This medication may be available under multiple brand names and/or in several different forms.
