Cosentyx (secukinumab) is a medication used to treat various autoimmune diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. While Cosentyx is generally considered safe, like all medications, it can cause side effects.

According to the Cosentyx website [2], the most common side effects of Cosentyx include diarrhea, upper respiratory infections, and reactions at the injection site, such as redness, itching, or pain. Other potential side effects may include flu-like symptoms, headache, and high blood pressure. It is important to note that not everyone experiences side effects, and those who do may not experience all of them.

In rare cases, Cosentyx can cause more severe side effects. These can include severe allergic reactions, infections, and exacerbation of inflammatory bowel disease. Patients who experience any of these symptoms should seek medical attention immediately.

It is important to talk to your doctor about any potential side effects before starting treatment with Cosentyx. Patients with a history of certain medical conditions or who are taking certain medications may be at higher risk for side effects.

In conclusion, while Cosentyx is generally considered safe, it can cause side effects. The most common side effects are mild and may include diarrhea, upper respiratory infections, and reactions at the injection site. Patients who experience severe side effects should seek medical attention immediately. It is important to talk to your doctor about any potential side effects before starting treatment with Cosentyx.
