Living with chronic skin conditions like plaque psoriasis can feel exhausting and overwhelming. The visible patches, intense itching, and physical pain often take a heavy toll on your daily life and mental health. If you have tried various creams and traditional pills without finding relief, your doctor might suggest a biologic treatment. Brodalumab is an advanced, targeted injection designed to help clear severe psoriasis when other treatments have failed.
Navigating a new biologic medicine can feel confusing at first. This patient-friendly guide breaks down everything you need to know about Brodalumab. We will explore how it works, what you need to tell your doctor before starting, how to use it safely, and what side effects to watch for along the way.
Key Takeaways About Brodalumab
- Brodalumab is a prescription biologic injection given under the skin to treat moderate-to-severe plaque psoriasis.
- It works by targeting a specific chemical messenger in your immune system to calm down skin inflammation.
- You must screen for tuberculosis and discuss your mental health history with your doctor before starting treatment.
- Watch closely for any sudden mood changes, signs of infection, or allergic reactions while using this medicine.
- Store your pre-filled syringes safely in the refrigerator and dispose of used needles in a proper sharps container.

What Type of Medicine Is Brodalumab?
Brodalumab is not a standard pill that you swallow every day. It belongs to a specialized class of advanced medicines known as monoclonal antibodies. These are lab-made proteins designed to target specific parts of your immune system.
Your immune system normally protects your body from harmful germs and infections. However, when you have plaque psoriasis, your immune system becomes overactive and mistakenly attacks healthy skin cells. This faulty process leads to rapid skin cell buildup, thick red patches, and silvery scales.
Brodalumab works by blocking a specific protein signal called interleukin-17 receptor. By stopping this chemical message, the medicine interrupts the cycle that causes severe skin inflammation. Over time, your skin can heal, clearing up the stubborn patches and easing your discomfort.
Doctors typically prescribe this medicine only when other topical creams, light therapies, or traditional systemic medicines have not worked well enough for your moderate-to-severe plaque psoriasis.
Important Things to Tell Your Doctor Before Starting
Before you take your first dose of Brodalumab, your doctor needs a complete review of your medical history. This medicine affects your immune system, so it is not safe for everyone. Be completely honest and share all details about your health.
Review the checklist below and tell your doctor if any of these conditions apply to you:
| Health Condition | Why It Matters for Brodalumab |
|---|---|
| Active Infections | Any current fever, flu, or ongoing infection must be cleared up before starting this medicine. |
| Tuberculosis (TB) | You must be tested for TB. If you have latent or active TB, it must be treated first. |
| Crohn Disease | Brodalumab can sometimes worsen inflammatory bowel diseases like Crohn disease. |
| Mental Health Issues | History of depression or suicidal thoughts requires careful discussion and monitoring. |
| Recent Vaccines | Certain live vaccines should be avoided while you are on this biologic therapy. |
| Pregnancy or Nursing | Discuss potential risks if you are pregnant, planning to become pregnant, or breastfeeding. |
How to Use Brodalumab Correctly
Brodalumab comes as a liquid medicine inside a pre-filled syringe. It is given as a subcutaneous injection, meaning it goes directly into the fatty layer right beneath your skin. Doctors may give you the first doses in a clinic, or they may teach you how to inject yourself at home.
Always follow your doctor or nurse's exact instructions on how to prepare and give your dose. Never change your schedule or take more medicine than prescribed.
Safe needle disposal is a vital part of your routine. Never throw used needles or syringes into a regular household trash can, as this puts sanitation workers at risk of accidental needle sticks. Always place used injection tools into a puncture-resistant sharps container. If you need a sharps container, ask your doctor or pharmacist where to get one.
What to Do If You Miss a Dose
Staying on your regular injection schedule helps keep your psoriasis under control. If you forget to take your dose on the scheduled day, inject it as soon as you remember. Then, continue with your normal dosing routine.
Never take a double dose to make up for a missed injection. Taking extra medicine will not help and can increase your risk of unwanted side effects.
What to Do If You Take Too Much
If you accidentally inject more Brodalumab than prescribed, do not panic. However, you should take action right away. Contact your doctor right away or go to the nearest hospital emergency department for medical evaluation.
Things to Watch Out For During Treatment
While you are using Brodalumab, you need to monitor your health closely and stay in touch with your care team. Watch for any unusual changes in your physical or emotional well-being.
Pay special attention to your mental health. Some patients taking this medicine have experienced mood changes, worsening depression, or thoughts of self-harm. If you, your family members, or your friends notice unusual mood swings, severe sadness, or sudden irritability, call your doctor right away.
Because Brodalumab lowers certain immune responses, your body may fight off germs less effectively. Stay away from people with contagious illnesses if possible. Wash your hands often and report any early signs of infection, such as fever, chills, or a persistent cough, to your doctor.
Ensure you complete any required tuberculosis screening tests before beginning your injections. If your doctor prescribes treatment for latent tuberculosis, finish that full course before taking Brodalumab.
Always consult your doctor before receiving any vaccines. Live virus vaccines are generally unsafe while taking biologic medicines that affect your immune system.
Possible Side Effects of Brodalumab
Like all medicines, Brodalumab can cause side effects, though not everyone experiences them. Knowing what to look for helps you get prompt medical care if something feels wrong.
Call your doctor or seek emergency medical care right away if you notice signs of a severe allergic reaction, such as a rash, hives, swelling of your face, lips, or tongue, or trouble breathing.
Other symptoms that require prompt medical attention include persistent fever, severe sore throat, worsening abdominal pain, or sudden dark mood changes.
Common, milder side effects that usually do not require emergency care include headaches, nausea, muscle aches, joint stiffness, fatigue, or mild reactions at the injection site. If these symptoms become bothersome or do not go away, talk to your doctor during your next visit.
Other Medicines That May Interact with Brodalumab
Certain drugs can interact with Brodalumab, changing how well the medicine works or raising your risk of side effects. Make sure your doctor has an up-to-date list of every single product you use.
Tell your doctor about all prescription drugs, over-the-counter medicines, herbal supplements, vitamins, and traditional remedies you take. Pay special attention to live virus vaccines, blood thinners like warfarin, immunosuppressants like cyclosporine, and sedative medicines like midazolam.
When to Seek Emergency Medical Help
Call 911 (US/Canada), 999 (UK), or your local emergency number right away, or go to the nearest hospital emergency department if you experience sudden trouble breathing, swelling of the face or throat, severe chest pain, or sudden overwhelming thoughts of self-harm.
