How often is Cosentyx (secukinumab) taken for plaque psoriasis?
For plaque psoriasis, Cosentyx is usually taken on a schedule based on the initial “loading” phase followed by maintenance dosing. The dosing schedule is:
- Loading (first doses): 300 mg once weekly
- After loading: 300 mg every 4 weeks (maintenance)
This weekly-to-every-4-weeks pattern is typical for standard plaque psoriasis dosing with secukinumab.
What if you’re taking a 150 mg dose instead of 300 mg?
Some patients may use 150 mg instead of 300 mg. When 150 mg is used, the maintenance interval is still commonly every 4 weeks after the initial weekly loading phase, following the prescriber’s dosing plan for that dose strength.
When do you switch from weekly dosing to every-4-weeks dosing?
The switch happens after the initial loading period (once-weekly dosing early in treatment), then it changes to every 4 weeks for ongoing maintenance.
What happens if you miss a dose?
If you miss a dose, the usual approach is to take it as soon as you remember and then resume the regular schedule. Because the correct timing depends on how far along you are in the treatment cycle, the prescriber or dispensing pharmacy is the best source for your specific situation.
Can the schedule change for psoriatic arthritis or special cases?
Cosentyx dosing schedules can differ for other conditions (like psoriatic arthritis) or based on how the prescribing clinician sets up treatment for a patient. If you’re taking Cosentyx for multiple diagnoses, ask your clinician which schedule applies to your psoriasis dosing specifically.

No sources were provided with the question, so I can’t cite the exact prescribing-label schedule here. If you share whether you’re using 150 mg or 300 mg (and whether it’s for plaque psoriasis only or also psoriatic arthritis), I can help interpret the right dosing pattern more precisely.
