When considering the use of Cosentyx (secukinumab), a biologic medication used to treat various conditions such as plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis, it is crucial to exercise caution when used in conjunction with certain other drugs. While the provided sources do not offer an exhaustive list of such drugs, they do offer some insight into potential interactions and considerations.

First, Cosentyx may affect the immune system, which could lead to a higher risk of infections [1]. Therefore, patients should be carefully monitored for signs of infection while on Cosentyx, and caution should be exercised when considering concomitant use of immunosuppressive therapies.

Second, Cosentyx is metabolized by the liver through multiple pathways, including CYP450 enzymes [2]. While no specific drug interactions have been identified, it is essential to consider the potential for interactions with other drugs metabolized by these enzymes. However, no specific drugs are mentioned in the sources provided.

Lastly, Cosentyx may increase the risk of inflammatory bowel disease (IBD) [3]. Therefore, patients with a history of IBD or symptoms suggestive of IBD should be closely monitored while on Cosentyx.

In summary, caution should be exercised when using Cosentyx with other immunosuppressive therapies, drugs metabolized by CYP450 enzymes, and in patients with a history of inflammatory bowel disease. However, it is essential to consult a healthcare professional or pharmacist for a comprehensive understanding of potential drug interactions and individual patient considerations.
