Your Complete Guide to Apremilast: Dosage, Forms, and Side Effects

Managing psoriasis is like playing a never-ending game of strategy. Flare-ups, side effects, and treatment routines all need to be juggled. And when it comes to choosing between topical and oral apremilast, the stakes feel even higher.

Both options come with their own set of perks and challenges, but which one truly fits your needs?

Apremilast: What You Need to Know

Apremilast, commonly known as Otezla, is a phosphodiesterase-4 (PDE4) inhibitor. In plain English? It helps regulate the inflammatory response behind psoriasis and psoriatic arthritis. This skincare treatment works, no doubt. But how you take it—topically or orally—can drastically impact your experience.

Topical apremilast: the new kid on the block

Apremilast in cream form is the latest entrant into the psoriasis treatment space, and it’s designed primarily for mild to moderate cases. Here’s the breakdown:

Pros Cons
Targeted Action: Goes straight to the affected area to reduce systemic exposure. Limited Reach: Not ideal for widespread or severe psoriasis.
Fewer Side Effects: No systemic impact means fewer risks like nausea or weight loss. Requires Consistency: Daily applications can be tedious.
Easy to Use: No pills or prescriptions for full-body treatment—just a cream or gel.  

Topical apremilast offers a focused treatment but it does demand commitment. If remembering to apply it daily sounds like a challenge, then this might not be your best bet.

Oral apremilast: a trusted veteran

Oral apremilast (Aprezo) has been a go-to solution for moderate to severe psoriasis and psoriatic arthritis for years. It has a proven track record, but it’s not without its own challenges.

Pros Cons
Systemic Effectiveness: Treats psoriasis from the inside out, ideal for widespread cases. Side Effects: Initial weeks can bring nausea, diarrhea, and headaches.
Convenience: One pill a day. Simple. Cost Concerns: Branded medication can be pricey, even with insurance.
Well-Studied: Years of research support its efficacy and safety.  

For those dealing with extensive psoriasis, the oral method provides the better choice—but it does require some patience as your body adjusts.

Efficacy: which one wins?

Topical apremilast

Topical apremilast is a strong option for localized plaques, with studies showing it significantly improves skin condition with consistent application. Since it has minimal systemic absorption, side effects are rare, making it a well-tolerated choice for long-term management.

Another key benefit? It’s easy to integrate into daily routines—provided you’re disciplined about sticking to the application schedule.

Oral apremilast

For moderate to severe cases, oral apremilast remains a proven solution. Some patients achieve PASI 75 (75% reduction in symptoms) within 16 weeks, highlighting its systemic effectiveness. By working deep within inflammatory pathways, it offers broad coverage—ideal for individuals whose psoriasis extends beyond localized areas. However, while it delivers comprehensive treatment, it does come with a higher risk of side effects, such as gastrointestinal discomfort and potential weight loss.

In all, 844 patients were randomized (n = 282, placebo; n = 562, apremilast). At week 16, significantly more patients taking apremilast achieved 75% or greater reduction from baseline Psoriasis Area and Severity Index score (PASI-75) (33.1%) versus placebo (5.3%, P < .0001; primary end point) (Apremilast, an oral phosphodiesterase 4 (PDE4) inhibitor, in patients with moderate to severe plaque psoriasis: Results of a phase III, randomized, controlled trial (Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis [ESTEEM] 1) – PubMed).

Safety profile: what’s the risk?

Apremilast is available in both topical and oral forms, each with distinct safety profiles.

Topical

Due to minimal systemic absorption, topical apremilast primarily causes localized side effects. The most common adverse reactions are application site reactions, such as erythema, pruritus, and burning sensations.

These reactions are generally mild to moderate in severity and tend to resolve with continued use. Systemic side effects are rare, making it a suitable option for patients concerned about widespread effects.

Oral

Oral apremilast is effective for treating psoriatic conditions but carries a risk of systemic side effects. Common adverse reactions include gastrointestinal issues like diarrhea and nausea, which often occur within the first few weeks of treatment.

Patients may also experience weight loss; regular monitoring is advised to manage these potential side effects.

Apremilast-induced diarrhea is usually self-limiting and resolves in the first few weeks of treatment. If pharmacological intervention is deemed necessary, secretory diarrhea could be treated effectively with racecadotril, an antisecretory agent that can be used for the treatment of apremilast-induced diarrhea (Multidisciplinary Management of the Adverse Effects of Apremilast – ScienceDirect).

Real-life considerations: which fits your lifestyle?

Condition Recommendation
Mild psoriasis Topical apremilast offers targeted relief without systemic risks.
Widespread psoriasis or psoriatic arthritis Oral apremilast provides more coverage.
Sensitive skin Topicals may be gentler, especially for those prone to irritation.
On-the-go lifestyles Oral is effortless, while topicals demand daily application.

Which should you choose?

There’s no one-size-fits-all answer here. Your choice depends on your symptoms, lifestyle, and comfort level with side effects.

  • Mild, localized psoriasis? Topical is a smart, low-risk option.
  • Moderate to severe or widespread psoriasis? Oral apremilast delivers systemic relief.

Having a better understanding of your treatment options is about more than just managing symptoms—it’s about regaining control over your skin and your life. Whichever route you take, the right method will help you keep psoriasis in check while staying true to your lifestyle.
