Recommended Dose of Upadacitinib for Moderate to Severe Psoriasis
For moderate to severe psoriasis, upadacitinib 15 mg once daily is the recommended dose, though this remains an off-label use as upadacitinib is not FDA-approved for psoriasis. 1
FDA-Approved Dosing for Related Conditions
While upadacitinib lacks FDA approval specifically for plaque psoriasis, the FDA-approved dosing for psoriatic arthritis provides the most relevant guidance:
- Standard dose: 15 mg once daily for psoriatic arthritis 1
- The 30 mg dose has been studied but is not the recommended dose for psoriatic arthritis despite showing superior efficacy 1, 2
Evidence Supporting 15 mg Dosing in Psoriasis
Psoriatic Arthritis Data (Most Relevant)
- In patients with psoriatic arthritis, 52.3% achieved PASI75 at one year with 15 mg daily 3
- At 12 weeks, 52% achieved ASAS 40 response in ankylosing spondylitis trials 4
- The 15 mg dose demonstrated 70.6% ACR20 response at week 12, which was noninferior to adalimumab 2
Higher Dose Considerations
- The 30 mg dose showed 78.5% ACR20 response and was superior to adalimumab 2
- However, adverse events were more frequent at 30 mg (72.3%) compared to 15 mg (66.9%) 2
- Serious infections occurred in 2.6% with 30 mg versus 1.2% with 15 mg 2
- Hepatic disorders were more common at 30 mg (12.3%) versus 15 mg (9.1%) 2
Dose Adjustments for Special Populations
Renal Impairment
- Maximum 15 mg daily for severe renal impairment (creatinine clearance <30 mL/min) 4
- No adjustment needed for mild-to-moderate renal impairment 4
Hepatic Impairment
- No dosage adjustment for mild or moderate hepatic impairment (Child-Pugh A/B) 4
- Contraindicated in severe hepatic disease (Child-Pugh C) 4
Critical Safety Considerations
Baseline Contraindications
Do not initiate if: 1
- Lymphocyte count <500 cells/mm³
- Absolute neutrophil count <1,000 cells/mm³
- Hemoglobin <9 g/dL
Mandatory Discontinuation Thresholds
Stop immediately if: 5
- Hemoglobin <8 g/dL or drops >2 g/dL
- ANC <500/mm³
- Lymphocyte count <500/mm³
Age and Cardiovascular Risk
- Increased serious infection risk in patients ≥65 years 5
- Five-fold increased pulmonary embolism risk with higher doses compared to TNF inhibitors 6, 5
- Increased major adverse cardiovascular events in patients >50 years with cardiovascular risk factors 5
Clinical Context and Limitations
Important caveat: Upadacitinib is not FDA-approved for plaque psoriasis 3. The evidence base consists primarily of:
- Psoriatic arthritis trials where skin outcomes were secondary endpoints 1, 2
- Case series showing complete remission in overlapping psoriasis/atopic dermatitis 3
- Phase 2 ankylosing spondylitis data 4
No phase 3 trials have evaluated upadacitinib specifically for plaque psoriasis 3, making this an off-label use that requires informed consent and careful patient selection.
Practical Algorithm
Confirm patient is appropriate candidate:
Initiate at 15 mg once daily 1
Monitor closely:
Consider alternative therapies first: Given the lack of FDA approval for psoriasis and significant safety concerns, FDA-approved biologics targeting IL-17, IL-23, or TNF-α should generally be prioritized over off-label upadacitinib 4
