Choose an injection site • STELARA is given by injection under your skin (subcutaneously) • Good places for the injection are the upper thigh or around the belly (abdomen) at least 5 cm away from the navel (belly button) • If possible, do not use areas of skin that show signs of psoriasis • If someone will assist in giving you the injection, then he or she may also choose the upper arms or buttocks as an injection site.
