How is ustekinumab used to treat psoriatsis?

Donna Hill Howes, RN
Family Practitioner

Ustekinumab (Stelara) blocks certain immune system proteins (IL-12 and IL-23) that can cause skin inflammation in people with psoriasis. It is prescribed for people with moderate-to-severe plaque psoriasis or psoriatic arthritis. It is given as an injection under the skin. After the first shot, another one is given 4 weeks later, and then every 12 weeks after that. Ustekinumab is very effective for improving psoriasis symptoms.
