Otezla (Generic Apremilast) Overview
Otezla is the brand name for a medication called apremilast. The generic version offers the same active ingredient as the brand-name drug at a lower cost. Apremilast belongs to a drug class called phosphodiesterase-4 (PDE-4) inhibitors.
This medication works by blocking a protein in your body that causes inflammation. Inflammation is the root cause of several skin and joint conditions. By reducing this inflammation, Otezla helps calm your immune system and relieve symptoms. The drug is taken by mouth as a tablet, making it convenient for daily use at home.
Otezla is approved to treat three main conditions: moderate to severe plaque psoriasis (a skin condition with thick, scaly patches), psoriatic arthritis (joint pain and swelling linked to psoriasis), and behçet's disease (a rare condition that causes mouth sores). Many patients find that Otezla provides relief when other treatments haven't worked well enough. If you're considering this medication, discuss your symptoms and medical history with your doctor to determine if it's right for you.
Side Effects
Most people tolerate Otezla reasonably well, especially after the first few weeks. Side effects tend to be mild to moderate and often improve as your body adjusts to the medication.
Common Side Effects
Nausea and vomiting — Affects many patients early on but usually decreases after a few weeks; taking the medication with food may help.
Diarrhea — One of the most common side effects; staying hydrated and eating a balanced diet can ease this symptom.
Headaches — Mild to moderate headaches may occur in the first few weeks of treatment.
Upper respiratory infections — Some patients experience increased cold or sinus infections while taking Otezla.
Abdominal pain — Stomach discomfort is possible, particularly early in treatment.
Fatigue — Mild tiredness or low energy may develop as your body adjusts.
Serious Side Effects
Severe diarrhea or dehydration — If diarrhea becomes severe and you cannot keep fluids down, contact your doctor immediately.
Mood changes or depression — In rare cases, some patients report feeling more depressed or anxious; report any mood shifts right away.
Severe allergic reactions — Rash, swelling of the face or throat, or difficulty breathing require emergency care.
Low white blood cell count — This increases infection risk; watch for signs like fever, chills, or unusual fatigue.
Liver problems — Yellowing of skin or eyes, dark urine, or severe abdominal pain may indicate liver issues.
When to Seek Medical Attention
Contact your doctor if side effects worsen or don't improve after a few weeks. Seek immediate care if you experience severe allergic reactions, chest pain, difficulty breathing, or signs of infection like high fever. If you develop mood changes, severe diarrhea with signs of dehydration, or yellowing of your skin or eyes, call your healthcare provider right away.

Important: Never stop taking Otezla without talking to your doctor first, even if you're feeling better. If you miss a dose, take it as soon as you remember, but skip it if your next dose is coming up soon. Do not double up on doses. Your doctor may adjust your dose based on how well the medication works and any side effects you experience.
Drug Interactions
Otezla can interact with other medications and substances, changing how well it works or increasing side effects. Always tell your doctor and pharmacist about all the medicines, supplements, and herbal products you take.
Strong CYP3A4 Enzyme Inducers (like Rifampin)
Medications that strongly induce the CYP3A4 enzyme may lower apremilast levels in your blood, reducing how well Otezla works. Your doctor may need to adjust your dose if you're taking these drugs together.
Moderate CYP3A4 Inhibitors (like Ketoconazole)
Drugs that block CYP3A4 enzyme activity can increase apremilast levels, raising the risk of side effects. Your doctor may lower your Otezla dose or monitor you more closely when using these medications together.
NSAIDs (Nonsteroidal Anti-Inflammatory Drugs)
Common pain relievers like ibuprofen or naproxen may be used alongside Otezla, but combining them increases stomach upset risk. Take NSAIDs with food and discuss long-term use with your doctor.
Other PDE-4 Inhibitors
Taking Otezla with other PDE-4 inhibitors is not recommended, as it increases the risk of side effects and overdose complications.
Immunosuppressant Medications
If you're taking drugs that weaken your immune system, combining them with Otezla may further increase infection risk and should be discussed with your doctor.
Oral Contraceptives (Birth Control Pills)
Otezla does not affect most birth control pills, but inform your doctor if you're using hormonal contraception to ensure safe combined use.
