and i haven't really had to think about it. real people with psoriasis... look and feel better with cosentyx. don't use if you're allergic to cosentyx. before starting get checked for tuberculosis. an increased risk of infections and lowered ability to fight them may occur. tell your doctor about an infection or symptoms if your inflammatory bowel disease symptoms develop or worsen... or if you've had a vaccine or plan to. serious allergic reactions may occur. ask your dermatologist about cosentyx.
