Cosentyx is a prescription drug used to treat autoimmune diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. Like all medications, it may cause side effects. The duration of these side effects can vary depending on the individual and the severity of the symptoms.

According to Drug Patent Watch [1], the most common side effects of Cosentyx are infections, diarrhea, and upper respiratory tract infections. These side effects usually go away on their own within a few days to a week. However, if the side effects persist or worsen, it is essential to consult a doctor.

Medical News Today [2] reports that some people may experience injection site reactions, such as redness, swelling, or itching. These side effects typically last for a few days and go away on their own. In rare cases, the injection site may become infected, which may require medical attention.

SingleCare [3] states that Cosentyx may also cause more severe side effects such as allergic reactions, liver damage, and nervous system problems. These side effects may last longer and require medical attention. Patients who experience severe side effects should contact their doctor immediately.

In conclusion, the duration of Cosentyx side effects can vary depending on the individual and the severity of the symptoms. Most side effects, such as infections, diarrhea, and upper respiratory tract infections, typically go away within a few days to a week. However, more severe side effects, such as allergic reactions, liver damage, and nervous system problems, may require medical attention. If you experience any side effects while taking Cosentyx, it is essential to consult your doctor.
