What is the Cosentyx (secukinumab) dose for plaque psoriasis?
For plaque psoriasis, Cosentyx dosing depends on whether the person is starting treatment and whether the disease is “moderate to severe.”
The standard adult dosing schedule is:
- Loading phase: 300 mg once weekly for 5 weeks (given as two injections of 150 mg each, for a total of 300 mg per dose).
- Maintenance phase: then 300 mg every 4 weeks.
Some patients may be treated with 150 mg every 4 weeks as a lower-dose maintenance option if their prescriber decides it’s appropriate.
How is the 150 mg vs 300 mg dosing chosen?
Clinicians typically use disease severity and response to treatment to decide between:
- 150 mg every 4 weeks, or
- 300 mg every 4 weeks after the initial weekly loading doses.
If you tell me the patient’s age, weight (if relevant), and whether they’re using Cosentyx for adult plaque psoriasis vs pediatric, I can narrow down what dosing schedule is most likely to match your situation.
Is the dosing the same for psoriatic arthritis?
Cosentyx dosing for psoriatic arthritis can overlap with plaque psoriasis starting regimens, but the follow-on maintenance interval and target dose can differ based on the indication and severity. If your question is actually about psoriatic arthritis, say so and I’ll tailor the schedule.
What if symptoms don’t improve after starting?
Cosentyx dosing can be adjusted based on how well psoriasis responds during the early weeks of treatment. The key point is that the first 5 weekly doses are part of the typical approach, then therapy continues on a regular schedule (often every 4 weeks at 300 mg, or sometimes 150 mg depending on the prescriber’s plan).
If you share how long the patient has been on Cosentyx and what improvement (if any) has occurred, I can describe how dosing adjustments are commonly approached in practice.
