Cosentyx is a medication used to treat several conditions, including psoriasis and psoriatic arthritis. The medication's active ingredient is secukinumab, which works by blocking a protein called interleukin-17A, which plays a role in inflammation. [1]

According to Healthline, the most common side effects of Cosentyx are upper respiratory infections, diarrhea, and reactions at the injection site. However, the medication can also cause more severe side effects, such as infections, allergic reactions, and depression. [2]

Neither of the sources provided any information about Cosentyx impacting appetite or cravings. However, Medical News Today notes that Humira, another medication used to treat psoriasis and psoriatic arthritis, can cause changes in appetite and weight gain. [3]

It's important to note that everyone's experience with medication can be different, and side effects can vary from person to person. If you have concerns about how Cosentyx may affect your appetite or cravings, it's best to discuss them with your healthcare provider.
