What is the typical cosentyx dose per injection for psoriatic arthritis?

What dose is used for psoriatic arthritis?

For adults with psoriatic arthritis, Cosentyx is started with weekly injections of 150 mg for the first five weeks, then switched to once-monthly maintenance. Some patients receive a 300 mg monthly dose instead if their doctor determines it needed.

Why do doctors choose 150 mg versus 300 mg?

The 150 mg dose is the standard for most patients. The 300 mg option applies when patients show no response after 16 weeks at 150 mg, or when they simultaneously have moderate to severe plaque psoriasis. Response is tracked by joint swelling and pain improvements.

What happens if a patient misses a dose?

If a patient misses a scheduled injection, it should be taken as soon as possible. The next scheduled dose is then set from that point on. No loading doses are required when restarting after breaks.

How does this dose schedule differ from other conditions?

The 150 mg weekly-for-five-weeks then monthly pattern applies also to ankylosing spondylitis. For active psoriatic arthritis in patients under 18, pediatric dosing is based on body weight and needs a separate prescription.

Can biosimilars compete before Cosentyx’s patent expires?

Cosentyx’s core U.S. patent expires in 2033. Current litigation and multiple biosimilar applications submitted by competitors mean early entry could occur if those challenges succeed.
