Cosentyx is a medication used to treat various conditions, including psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. According to the official Cosentyx website, the recommended dose for seniors is the same as for adults, which is 300 mg administered subcutaneously every four weeks after the initial loading dose [3]. The loading dose is typically given as two injections of 150 mg each, one week apart [3].

However, it is important to note that the frequency of administration and dosing of Cosentyx may vary depending on the individual's condition and response to treatment. Therefore, it is essential to consult with a healthcare provider to determine the appropriate dosing schedule for each patient.

In November 2021, President Biden announced a prescription drug pricing plan that aims to lower the cost of prescription drugs for Americans, including seniors [2]. The plan includes allowing Medicare to negotiate drug prices and capping out-of-pocket costs for seniors [2]. However, it is unclear how this plan will affect the pricing and availability of Cosentyx.

In conclusion, the recommended dosing schedule for Cosentyx for seniors is 300 mg administered subcutaneously every four weeks after the initial loading dose. However, the dosing may vary depending on the individual's condition and response to treatment, and it is crucial to consult with a healthcare provider. It is also important to monitor any updates regarding the pricing and availability of Cosentyx, especially with the proposed prescription drug pricing plan by President Biden.
