Cosentyx (secukinumab) is a biologic drug used to treat psoriasis, psoriatic arthritis, and ankylosing spondylitis. While it is an effective medication, it can also cause severe side effects.

However, there are also more severe side effects, such as allergic reactions, liver damage, and inflammatory bowel disease.

To prevent severe side effects, it is essential to follow the prescribing doctor's instructions carefully.

To prevent infections, patients should practice good hygiene, such as washing their hands frequently and avoiding contact with sick individuals. Patients should also inform their doctor immediately if they develop any signs of an infection, such as fever, cough, or sore throat.

To prevent injection site reactions, patients should rotate the injection site and follow proper injection techniques. Patients should also inform their doctor if they develop any signs of an injection site reaction, such as redness, swelling, or pain.
