Cosentyx is a medication used to treat psoriasis, psoriatic arthritis, and ankylosing spondylitis. The FDA has approved Cosentyx for these uses, but it has also issued some warnings about its use.

According to the FDA label for Cosentyx, there are several warnings and precautions that patients and healthcare providers should be aware of. These include the risk of infections, including tuberculosis and other serious infections, as well as the risk of allergic reactions. The label also warns that patients who have a history of inflammatory bowel disease may be at an increased risk of worsening symptoms while taking Cosentyx.

In addition to the warnings on the label, a study published in the Journal of Clinical and Aesthetic Dermatology [3] found that Cosentyx may be associated with an increased risk of fungal infections. The study authors noted that while fungal infections are not typically a major concern with biologic medications like Cosentyx, they observed several cases of fungal infections in patients taking the drug.

It is important for patients taking Cosentyx to be aware of these risks and to report any symptoms or side effects to their healthcare provider. As with any medication, the benefits and risks of Cosentyx should be carefully considered before starting treatment.
