Standard Dosing Schedule for Cosentyx
Cosentyx (secukinumab) is injected subcutaneously. For plaque psoriasis in adults, the typical schedule starts with 300 mg (two 150 mg doses) at weeks 0, 1, 2, 3, then 300 mg every 4 weeks.[1] This means monthly maintenance after the initial loading doses, not weekly.
Dosing for Psoriatic Arthritis and Ankylosing Spondylitis
Adults receive 150 mg (one injection) at weeks 0, 1, 2, 3, then every 4 weeks. Some cases use 300 mg if response is inadequate. Again, monthly after loading.[1]
Pediatric Dosing (Ages 6+ for Psoriasis)
Weight-based: For 50 kg or more, same as adults (300 mg loading, then every 4 weeks). Under 50 kg, 150 mg loading, then every 4 weeks. No weekly option.[1]
How It's Administered
Use prefilled syringes or autoinjectors. Sites rotate (thigh, abdomen, upper arm). Loading doses are weekly at first (weeks 0-3), but maintenance shifts to monthly.[1]
Missed Dose Instructions
Inject as soon as possible if within a week of schedule. Resume normal timing afterward—don't double up.[1]
Who Decides the Schedule?
Dosing follows FDA-approved labeling from Novartis, but prescribers adjust for response or conditions like hidradenitis suppurativa (300 mg weekly for 4 weeks, then every 4 weeks).[1] Always check with a doctor for personalized plans.
