What dose of secukinumab is used for psoriatic arthritis (PsA)?
For psoriatic arthritis, secukinumab (Cosentyx) is given as a subcutaneous injection at the standard PsA regimen used across most prescribing sources and practice:
- 150 mg once weekly for 5 weeks, then
- 150 mg once every 4 weeks thereafter.
Some patients may be treated with 300 mg under the prescriber’s direction (commonly when symptoms are more severe), following the same initial schedule pattern and then maintenance every 4 weeks.
How do the loading doses work?
Secukinumab uses a “loading” period to reach effective drug levels quickly:
- Weeks 0–4: doses are given weekly
- After week 4/5: dosing switches to every 4 weeks for maintenance
What if the patient starts at 300 mg—what changes?
If the clinician prescribes 300 mg for PsA, the key difference is the dose amount (not the schedule structure):
- Initial phase still follows weekly dosing for the first several weeks
- Maintenance still follows every 4 weeks
Does dosing differ for different types of psoriatic arthritis?
The same secukinumab dosing approach is typically used for psoriatic arthritis, including presentations that involve joints and/or enthesitis. If a patient is being treated for multiple related conditions (for example, psoriasis plus PsA), clinicians may adjust to a regimen that fits both the arthritis and skin disease goals.
What should patients know about missed doses?
If a dose is missed, patients generally should take it as soon as they remember and then continue on the original schedule. The exact instruction can depend on how far along the patient is in the dosing cycle, so prescribers often provide individualized guidance.
Are there special dosing adjustments?
Dose changes are generally driven by clinical response and tolerability, not kidney or liver adjustments for most patients in routine practice. Any comorbidities, infections, or concomitant therapies can affect how and when secukinumab is continued.
