What is Apremilast: Uses, Dosage, Side Effects and More

Apremilast is an oral medication that helps control inflammation in your body by targeting specific immune system pathways. It's commonly prescribed for conditions like psoriasis and psoriatic arthritis, where your immune system mistakenly attacks healthy skin and joint tissue. This medication works differently from many other treatments because it's taken as a pill rather than an injection, making it a convenient option for many people dealing with chronic inflammatory conditions.

What is Apremilast?

Apremilast belongs to a class of medications called phosphodiesterase 4 (PDE4) inhibitors. Think of it as a gentle brake system for your overactive immune response. When your immune system gets too enthusiastic and starts attacking healthy tissue, apremilast helps calm things down by blocking certain inflammatory signals inside your cells.

Unlike some other treatments for inflammatory conditions, apremilast doesn't suppress your entire immune system. Instead, it works more selectively, targeting specific pathways that drive inflammation. This targeted approach can mean fewer risks compared to medications that broadly dampen your immune response.

What is Apremilast Used For?

Apremilast is primarily prescribed for two main conditions where inflammation plays a central role. Your doctor might recommend it if you have moderate to severe plaque psoriasis or active psoriatic arthritis.

For psoriasis, apremilast helps reduce the red, scaly patches on your skin by calming the inflammatory process that causes rapid skin cell turnover. Many people notice improvements in their skin's appearance, along with reduced itching and discomfort.

In psoriatic arthritis, this medication can help ease joint pain, stiffness, and swelling. It may also help prevent further joint damage over time. Some people with psoriatic arthritis find that apremilast helps with both their skin symptoms and joint problems, since both conditions share similar inflammatory pathways.

Less commonly, doctors sometimes prescribe apremilast for certain types of mouth ulcers called aphthous ulcers, particularly in people with Behçet's disease. Your healthcare provider will determine if apremilast is right for your specific situation.

How Does Apremilast Work?

Apremilast works by blocking an enzyme called phosphodiesterase 4, which plays a key role in inflammation. When this enzyme is blocked, it reduces the production of inflammatory chemicals in your body while increasing anti-inflammatory substances.

This medication is considered a moderate-strength treatment option. It's not as aggressive as some immunosuppressive drugs, but it's more targeted than simple anti-inflammatory medications like ibuprofen. This balanced approach means it can be effective for many people while generally having a more manageable side effect profile.

The beauty of apremilast is that it works from the inside out. Rather than just treating symptoms on the surface, it addresses the underlying inflammatory process that drives conditions like psoriasis and psoriatic arthritis.

How Should I Take Apremilast?

Apremilast is taken by mouth, usually twice daily with or without food. Your doctor will typically start you on a lower dose and gradually increase it over the first week to help your body adjust to the medication.

The standard starting schedule involves taking one 10mg tablet in the morning on day one, then adding an evening dose on day two, and continuing to increase until you reach the full dose of 30mg twice daily. This gradual increase helps minimize potential stomach upset and other side effects.

You can take apremilast with meals if it bothers your stomach, though food isn't required for absorption. Some people find that taking it with a light snack helps reduce nausea, especially during the first few weeks of treatment.

Try to take your doses at roughly the same times each day to maintain steady levels in your bloodstream. Setting phone reminders can be helpful, especially when you're establishing this new routine.

How Long Should I Take Apremilast For?

Apremilast is typically a long-term treatment, and you'll likely need to take it continuously to maintain its benefits. Most people start seeing improvements in their symptoms within 2-4 weeks, with more significant results appearing after 12-16 weeks of consistent use.

The duration of treatment depends on your specific condition and how well you respond to the medication. For chronic conditions like psoriasis and psoriatic arthritis, stopping the medication often leads to symptoms returning, so ongoing treatment is usually necessary.

Your doctor will monitor your progress through regular check-ups and may adjust your treatment plan based on how you're responding. Some people take apremilast for years with good results, while others may need to switch to different treatments if it becomes less effective over time.

What Are the Side Effects of Apremilast?

Like all medications, apremilast can cause side effects, though not everyone experiences them. Understanding what to expect can help you feel more prepared and know when to contact your healthcare provider.

The most common side effects tend to be mild to moderate and often improve as your body adjusts to the medication:

• Diarrhea (affects about 1 in 6 people)
• Nausea and stomach upset
• Headache
• Upper respiratory tract infections
• Decreased appetite
• Weight loss
• Back pain
• Fatigue

Most of these side effects are temporary and tend to lessen after the first few weeks of treatment. The gradual dose increase at the start of treatment helps minimize many of these effects.

Some people experience mood changes, including feelings of depression or anxiety, while taking apremilast. While this is less common, it's important to pay attention to your emotional well-being and discuss any concerning changes with your doctor.

Rare but more serious side effects can include severe allergic reactions, significant weight loss, or worsening depression. If you experience difficulty breathing, severe skin reactions, or thoughts of self-harm, seek immediate medical attention.

Who Should Not Take Apremilast?

Apremilast isn't suitable for everyone, and certain health conditions or circumstances may make it inadvisable. Your doctor will carefully review your medical history before prescribing this medication.

You should not take apremilast if you're allergic to it or any of its ingredients. People with severe kidney problems may need dose adjustments or alternative treatments, as the medication is processed through the kidneys.

Special caution is needed if you have a history of depression, anxiety, or other mental health conditions. Apremilast can sometimes worsen these conditions, so your doctor will want to monitor you closely or consider other treatment options.

Pregnant or breastfeeding women should discuss the risks and benefits with their healthcare provider. While studies haven't shown clear harm, the safety of apremilast during pregnancy and breastfeeding isn't fully established.

If you're planning surgery or have an active infection, your doctor may temporarily pause your apremilast treatment. While it doesn't suppress the immune system as dramatically as some other medications, it's still important to ensure your body can heal properly.

Apremilast Brand Names

Apremilast is most commonly available under the brand name Otezla. This is the original brand version manufactured by Amgen (formerly Celgene).

Generic versions of apremilast may become available in some regions, though availability varies by country and healthcare system. Your pharmacist can help you understand what options are available in your area and whether generic substitution is appropriate for your situation.

Apremilast Alternatives

Several other treatment options exist for psoriasis and psoriatic arthritis, each with their own benefits and considerations. Your doctor can help you explore these alternatives if apremilast isn't the right fit for you.

For psoriasis, alternatives include topical treatments like corticosteroids and vitamin D analogs, phototherapy, traditional systemic medications like methotrexate, and biologic injections such as adalimumab or etanercept. Each option has different mechanisms of action and side effect profiles.

For psoriatic arthritis, alternatives might include traditional DMARDs (disease-modifying antirheumatic drugs) like methotrexate or sulfasalazine, biologic medications, or targeted synthetic DMARDs like tofacitinib. The choice depends on your specific symptoms, disease severity, and personal preferences.

Some people find that combining treatments works better than using a single medication. Your rheumatologist or dermatologist can help create a personalized treatment plan that addresses your unique needs and goals.

Is Apremilast Better Than Methotrexate?

Comparing apremilast to methotrexate isn't straightforward because they work differently and have distinct advantages. Both are effective treatments, but the "better" choice depends on your specific situation, preferences, and medical history.

Apremilast offers the convenience of oral dosing without the need for regular blood monitoring that methotrexate requires. It also doesn't suppress the immune system as broadly, which can mean fewer infection risks. However, methotrexate has been used longer and has more extensive research data supporting its effectiveness.

Methotrexate is often more effective for severe joint involvement in psoriatic arthritis and may work faster for some people. It's also typically less expensive than apremilast. However, it requires regular blood tests to monitor liver function and can cause more significant side effects in some people.

Your doctor will consider factors like your disease severity, other health conditions, lifestyle preferences, and previous treatment responses when recommending between these medications. Some people even use them together under careful medical supervision.
