Cosentyx is a biologic drug that is used to treat various inflammatory conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. As with any medication, there are potential side effects associated with its use.

According to the drug patent watch website [1], some of the most common side effects of Cosentyx include upper respiratory infections, diarrhea, and fungal infections. Other side effects may include allergic reactions, injection site reactions, and an increased risk of infections.

The Healthline website [2] also lists similar side effects, but it also notes that some patients may experience more serious side effects such as liver problems, heart failure, and nervous system problems. It is important to note that these serious side effects are rare, but they can occur.

The Cosentyx website [3] provides additional information on the safety and side effects of the drug. It notes that patients should contact their healthcare provider immediately if they experience any signs of an allergic reaction, such as hives, swelling, or difficulty breathing. The website also notes that patients should be monitored for signs of infection, such as fever or chills, while taking Cosentyx.

In conclusion, while Cosentyx can be an effective treatment for inflammatory conditions, it is important to be aware of the potential side effects associated with its use. Patients should discuss any concerns or questions they may have with their healthcare provider before starting treatment with Cosentyx.
