When considering medications to avoid while on Cosentyx (secukinumab), it is crucial to consult with a healthcare professional or pharmacist, as potential interactions may vary depending on individual health conditions and other factors. However, some general guidance can be provided based on the available information.

Cosentyx is a biologic medication used to treat several conditions, such as plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1]. Biologic medications like Cosentyx work by targeting specific proteins in the immune system, which may increase the risk of infections and limit the effectiveness of certain vaccines [1].

According to Drugs.com, there are no specific medications known to have harmful interactions with Cosentyx [2]. However, it is essential to inform healthcare professionals about all medications, supplements, and herbal products being taken, as they can provide personalized advice based on individual circumstances [1].

It is also important to note that live vaccines should be avoided while taking Cosentyx, as the medication may affect the immune system's ability to respond to the vaccine [1]. Examples of live vaccines include measles, mumps, and rubella (MMR) vaccine, varicella (chickenpox) vaccine, rotavirus vaccine, and the intranasal influenza (flu) vaccine [1]. Inactivated or recombinant vaccines, such as the inactivated influenza vaccine, are generally considered safe while on Cosentyx [1].

In summary, while there are no specific medications known to have harmful interactions with Cosentyx, it is essential to consult with healthcare professionals before starting or stopping any medications, supplements, or herbal products. Additionally, live vaccines should be avoided while taking Cosentyx [1][2].
