Guselkumab is a medication that falls under the category of biologic drugs, specifically a monoclonal antibody. It is used to treat moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.

This medication works by targeting a specific protein in the body that is involved in the inflammatory response that leads to psoriasis symptoms. By blocking this protein, Guselkumab helps to reduce the inflammation and skin cell overgrowth that are characteristic of psoriasis.

Guselkumab is typically administered as an injection under the skin, either by a healthcare provider or self-administered by the patient after proper training. The dosing schedule may vary depending on the individual’s response to the medication and the severity of their psoriasis.

As with any medication, Guselkumab may cause side effects in some individuals. Common side effects may include upper respiratory infections, headache, injection site reactions, and diarrhea. It is important to discuss any concerns or potential side effects with your healthcare provider.

It is important to note that Guselkumab may increase the risk of infections, including serious infections that may require hospitalization. Patients should be monitored for signs of infection while taking this medication.

Overall, Guselkumab has been shown to be an effective treatment option for individuals with moderate to severe plaque psoriasis. It is important to work closely with your healthcare provider to determine if Guselkumab is the right treatment option for you and to monitor your response to the medication.
