Cosentyx (secukinumab) is a prescription medication used to treat moderate to severe plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1]. While Cosentyx is generally considered safe, there are some precautions to keep in mind.

One important precaution is to inform your doctor if you have a history of infections or if you are currently experiencing any symptoms of infection, such as fever, chills, or sore throat. Cosentyx can increase the risk of infections, including serious infections, such as tuberculosis and invasive fungal infections [2]. It is important to avoid starting Cosentyx if you have an active infection.

Another precaution is to inform your doctor if you have a history of inflammatory bowel disease (IBD) or if you experience symptoms of IBD, such as diarrhea, abdominal pain, or blood in your stool. Cosentyx has been associated with exacerbation of IBD, including Crohn's disease and ulcerative colitis [3].

Additionally, Cosentyx may increase the risk of malignancies, including lymphoma and other cancers [1]. Patients should inform their doctor if they have a history of cancer or if they develop any unusual symptoms while taking Cosentyx.

Other potential side effects of Cosentyx include allergic reactions, injection site reactions, and liver function abnormalities [2]. Patients should inform their doctor if they experience any of these symptoms.

In conclusion, Cosentyx is generally considered safe, but it is important to inform your doctor of any pre-existing conditions or symptoms of infection or IBD. Patients should also be aware of the potential risk of malignancies and other side effects. As with any medication, it is important to follow your doctor's instructions and report any unusual symptoms or side effects.
