The recommended dose of Cosentyx (secukinumab) for seniors is the same as for younger adults. According to the official website of Cosentyx, the recommended dose for plaque psoriasis in adults is 300 mg administered by subcutaneous injection at weeks 0, 1, 2, 3, and 4 followed by 300 mg every 4 weeks. For active psoriatic arthritis, the recommended dose is 150 mg or 300 mg administered by subcutaneous injection every 4 weeks after an initial loading dose. The dosage for ankylosing spondylitis is 150 mg or 300 mg administered by subcutaneous injection every 4 weeks after an initial loading dose [2].

DrugPatentWatch, a database that provides information on pharmaceutical patents, does not provide specific dosing information for Cosentyx. However, Drugs.com, a reputable online resource for drug information, confirms the dosing regimen mentioned above for Cosentyx for the treatment of plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1, 3].

It is important to note that the recommended dosage of Cosentyx may be adjusted based on individual patient factors such as age, weight, and medical history. Therefore, seniors should consult their healthcare provider before starting or changing the dosage of Cosentyx [2].
