Daily Dose of Otezla
The recommended daily dose of Otezla (apremilast) for adults with plaque psoriasis or psoriatic arthritis is 30 mg twice daily (total 60 mg/day), taken orally starting on Day 6 after a 5-day titration schedule. 1
Standard Dosing Algorithm
Initial Titration (Days 1-5)
The titration schedule is mandatory to minimize gastrointestinal side effects 2, 1:
- Day 1: 10 mg (morning only)
- Day 2: 10 mg (morning) + 10 mg (evening)
- Day 3: 10 mg (morning) + 20 mg (evening)
- Day 4: 20 mg (morning) + 20 mg (evening)
- Day 5: 20 mg (morning) + 30 mg (evening)
- Day 6 onward: 30 mg (morning) + 30 mg (evening) = 60 mg total daily dose
Maintenance Dosing
After the 5-day titration, continue 30 mg twice daily indefinitely for both psoriatic arthritis and plaque psoriasis 1. This can be taken with or without food, and tablets must be swallowed whole—do not crush, split, or chew 1.
Critical Dose Adjustments
Severe Renal Impairment (CrCl <30 mL/min)
Reduce to 30 mg once daily after completing the modified titration 2, 1:
- Use only the AM doses from the standard titration schedule (skip all PM doses)
- Maintenance: 30 mg once daily (not twice daily)
This adjustment is essential because severe renal impairment significantly affects apremilast clearance 1.
Important Clinical Considerations
Gastrointestinal Tolerability
The titration schedule exists specifically because 70-80% of GI adverse effects (diarrhea, nausea) occur within the first 2 weeks, with 75-80% being mild and 60-65% resolving within the first month 2. Do not skip the titration—it substantially reduces treatment discontinuation 2.
Weight Monitoring
Monitor weight regularly. If weight loss exceeds 5% from baseline, strongly consider discontinuing apremilast 2. Weight decreases of 5-10% occurred in 12% of patients versus 5% on placebo 2.
Drug Interactions
Avoid concurrent use with strong CYP450 inducers (rifampin, phenobarbital, carbamazepine, phenytoin), as these reduce apremilast efficacy and are not recommended 2, 1.
Depression Risk
Screen for depression before initiating therapy. Depression occurred in approximately 1% of patients, and apremilast may worsen pre-existing depression 2. Appropriate counseling is recommended before starting treatment 2.
Special Populations
- Elderly patients: Use standard dosing but counsel about increased dehydration risk from GI side effects 2
- Pregnancy: Use only if benefit justifies potential fetal risk 2
- No laboratory monitoring required: Unlike methotrexate or cyclosporine, apremilast does not require routine lab monitoring 2
Common Pitfalls to Avoid
- Skipping titration: This dramatically increases GI side effects and discontinuation rates
- Forgetting renal dose adjustment: Patients with severe renal impairment need once-daily dosing, not twice-daily
- Not counseling about early GI effects: Patients who understand these are temporary and usually resolve are more likely to persist with treatment
- Missing weight loss: Regular weight checks are essential; >5% loss warrants discontinuation consideration
