Cosentyx is a biologic drug used to treat psoriasis, psoriatic arthritis, and ankylosing spondylitis. While the drug has been proven effective in treating these conditions, there are potential long-term risks associated with its use.

One of the main concerns with Cosentyx is its effect on the immune system. Cosentyx works by targeting a protein in the immune system called interleukin-17A, which can increase the risk of infections. This risk may be greater for patients who have a weakened immune system or who take other medications that suppress the immune system [1].

In addition, some studies have suggested that Cosentyx may increase the risk of cardiovascular events, such as heart attack or stroke. A study published in Arthritis Research & Therapy found that patients with psoriatic arthritis who were treated with Cosentyx had a higher risk of cardiovascular events compared to those who were treated with a placebo [2]. However, more research is needed to fully understand this potential risk.

Other potential side effects of Cosentyx include allergic reactions, gastrointestinal problems, and liver damage. Patients should talk to their doctor about any concerns they have about the risks and benefits of Cosentyx before starting treatment [3].

In conclusion, while Cosentyx can be an effective treatment for psoriasis, psoriatic arthritis, and ankylosing spondylitis, there are potential long-term risks associated with its use. Patients should talk to their doctor about these risks and any concerns they have before starting treatment.
