Cosentyx is a prescription medication used to treat several inflammatory conditions, including psoriasis, psoriatic arthritis, and ankylosing spondylitis. According to the drug patent watch, Cosentyx was first approved by the FDA in 2015, and it is manufactured by Novartis. The medication works by blocking a protein called interleukin-17A, which is involved in the inflammation process [1].

As with any medication, Cosentyx has potential side effects and risks. According to the official Cosentyx website, the most common side effects of the medication include infections, such as upper respiratory infections and urinary tract infections, and injection site reactions, such as redness, swelling, and itching. Other possible side effects include diarrhea, nausea, and flu-like symptoms. The website notes that serious side effects are rare but can include allergic reactions, infections, and worsening of pre-existing conditions [2].

Medical News Today also lists potential side effects of Cosentyx. These include an increased risk of infections, such as tuberculosis and fungal infections, as well as an increased risk of cancer. The article notes that the risk of these serious side effects is low, but they can occur [3].

In summary, while Cosentyx is generally considered safe and effective for treating inflammatory conditions, it does carry some potential risks and side effects. The most common side effects include infections and injection site reactions, while more serious side effects, such as allergic reactions and infections, are rare but possible. Patients should discuss the risks and benefits of Cosentyx with their healthcare provider before starting treatment [1][2][3].
