Apalutamide Overview
Apalutamide, sold under the brand name Erleada, is a prescription medication belonging to a class of drugs called androgen receptor inhibitors. It's designed to treat certain advanced forms of prostate cancer by blocking the activity of male hormones (androgens) that fuel cancer cell growth. This medication is typically used in men with metastatic castration-resistant prostate cancer—cancer that has spread beyond the prostate and no longer responds to standard hormone therapies.
The drug works by entering cancer cells and blocking the androgen receptor, a protein that allows male hormones to signal cancer cells to grow and divide. By cutting off this signal, apalutamide slows tumor growth and can help extend survival. It's often used alongside other prostate cancer treatments as part of a comprehensive care plan. Understanding how this medication works, what to expect during treatment, and how it compares to generic vs brand name drugs can help you make informed decisions about your health.
Side Effects
Most men tolerate apalutamide reasonably well, though side effects are common. The severity and type of side effects vary from person to person. Let your healthcare team know about any symptoms that concern you or interfere with daily life.
Common Side Effects
Fatigue – Feeling unusually tired or lacking energy is the most frequently reported side effect; it may improve over time.
High blood pressure – Apalutamide can elevate blood pressure; regular monitoring is recommended.
Rash – A mild to moderate skin rash may develop, often on the face, neck, or hands and usually fades with time.
Diarrhea – Loose stools or increased bowel movements may occur; staying hydrated helps manage this symptom.
Joint or muscle pain – Some men experience aches in joints or muscles, sometimes called musculoskeletal pain.
Loss of appetite – You may feel less hungry than usual, which can affect overall nutrition and energy levels.
Serious Side Effects
Falls or fractures – Apalutamide may weaken bones or increase fall risk; be cautious on stairs and in slippery areas.
Seizures – Though uncommon, seizures have been reported; seek immediate emergency care if this occurs.
Severe allergic reactions – Difficulty breathing, swelling of the face or throat, or severe rash require urgent medical attention.
Heart problems – Chest pain, shortness of breath, or irregular heartbeat may signal a serious cardiac issue.
Liver problems – Yellowing of skin or eyes, dark urine, or abdominal pain may indicate liver injury.
When to Seek Medical Attention
Contact your doctor right away if you experience chest pain, difficulty breathing, severe allergic symptoms, or signs of a seizure. Also report persistent fatigue that worsens, unexplained bruising, severe rash, or any symptom that concerns you. If you fall or suspect a fracture, seek medical evaluation promptly.

Drug Interactions
Apalutamide interacts with many medications and supplements because it's processed through the liver. These interactions may reduce the effectiveness of other drugs or increase your risk of side effects. Always tell your doctor about every medication, supplement, and herbal product you use before starting apalutamide.
Strong CYP3A4 Inhibitors
Medications like ketoconazole, itraconazole, and ritonavir can increase apalutamide levels in your bloodstream, raising the risk of side effects. Your doctor may lower your dose or choose a different medication.
Strong CYP3A4 Inducers
Drugs such as rifampicin and phenytoin can decrease apalutamide effectiveness by speeding up how your body breaks it down. Your doctor may need to adjust your dose or monitor you more closely.
Warfarin and Other Blood Thinners
Apalutamide may reduce the effectiveness of blood thinners like warfarin, increasing clot risk. Your doctor will monitor your blood clotting levels and may adjust your blood thinner dose.
Certain Cholesterol Medications
Statins and other lipid-lowering drugs may interact with apalutamide. Your doctor will determine if any dose adjustments are needed to maintain treatment effectiveness.
Herbal Supplements (St. John's Wort)
This popular herbal supplement can reduce apalutamide levels, making it less effective. Avoid St. John's Wort unless your doctor approves and monitors your treatment carefully.
Over-the-Counter Pain Relievers
NSAIDs like ibuprofen, when used long-term, may increase the risk of heart and kidney problems when combined with apalutamide. Discuss safe pain management options with your doctor.

Frequently Asked Questions
Get answers to common questions about apalutamide.
Most men continue taking apalutamide as long as it's controlling their cancer and they're tolerating side effects reasonably well. Your doctor will monitor your progress with imaging and blood tests (PSA levels) to determine if the medication is working. Treatment may continue indefinitely unless cancer progression occurs or side effects become unmanageable.
You should take apalutamide with food to improve absorption and reduce stomach upset. Taking it at the same time each day—such as with breakfast or dinner—helps you remember and maintains consistent medication levels in your body. Talk to your doctor if you have difficulty eating or swallowing pills.
Severe fatigue is one of the most common side effects. Try managing energy by resting, staying active within your limits, eating a balanced diet, and sleeping well. If fatigue worsens or interferes with daily activities, tell your doctor immediately. They may adjust your dose, recommend supportive treatments, or suggest lifestyle modifications.
Some supplements, especially St. John's Wort (used for mood), can reduce apalutamide effectiveness. Vitamin D and calcium supplements are often recommended to support bone health. Always inform your doctor about all supplements, vitamins, and herbal products you take, as they can interact with your cancer medication.
Most men see their oncologist every 1 to 3 months initially, then every 2 to 3 months once stable. These visits include blood work (PSA and liver/kidney function tests) and imaging (CT scans or bone scans) to monitor how well apalutamide is working and check for side effects. Your doctor will adjust the schedule based on your individual needs.
The Bottom Line
Apalutamide is an important treatment option for men with advanced prostate cancer that hasn't responded to standard hormone therapy. While it can slow cancer progression and extend survival, side effects like fatigue, high blood pressure, and bone weakness require careful management and regular monitoring. Understanding how this medication works, what side effects to expect, and how it compares to generic vs brand name drugs empowers you to make informed health decisions.
