How does this medication work? What will it do for me?
Brodalumab belongs to the class of medications called biological response modifiers ("biologics").
It is used to treat moderate-to-severe plaque psoriasis in adults whose specialists have determined that systemic or phototherapy may be beneficial. For people with plaque psoriasis, the body overproduces a protein called interleukin-17A (IL-17A). Increased levels of this protein can result in skin itching, pain, and scaling. Brodalumab recognizes this protein and blocks the action of IL-17A, reducing the symptoms of plaque psoriasis.

How should I use this medication?
The recommended starting dose of brodalumab is 210 mg injected subcutaneously (under the skin) once a week for 3 weeks. After 3 doses, the recommended dose is 210 mg injected every 2 weeks. Each dose is given as a single injection of 210 mg (1.5 mL). Each syringe is single-use only and should be safely discarded after injecting the dose.
Brodalumab is administered by subcutaneous injection in the thigh, abdomen, or outer upper arm. It is important to rotate the site of injection. Avoid injecting into areas that are tender, bruised, red, hard, or affected by psoriasis.
Do not shake this medication before using it. The solution for injection should be clear to slightly opalescent, and colourless-to-slightly-yellow. If it is cloudy or you can see lumps, flakes, or coloured particles in the solution, do not use it. To minimize discomfort, allow this medication to warm to room temperature for 30 minutes before injecting.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: In rare cases, some people may develop an allergic reaction to this medication. Signs of an allergic reaction include a severe rash, hives, swollen face or throat, or difficulty breathing. If these occur, seek medical attention immediately.
Crohn's Disease: If you have Crohn's disease, (a form of inflammatory bowel disease) brodalumab may make symptoms of this condition worse. During medication testing, some people with no history of Crohn's disease developed bowel symptoms. If you develop symptoms of inflammation in the digestive system, such as diarrhea, fatigue, fever, and abdominal pain or cramping, contact your doctor as soon as possible. People who have Crohn's disease should not use this medication.
Infections: This medication can increase the risk of developing an infection, including serious infections such as sepsis, pneumonia, and tuberculosis. Before starting brodalumab treatment, your doctor may test to see if you have tuberculosis. If you notice signs of an infection such as fever, chills, pain, swelling, coughing, or pus, contact your doctor as soon as possible. This medication should also not be started while you have an active infection.
Tell your doctor if you have a history of infections that keep coming back, or other conditions that might increase your risk of infections such as diabetes. While you are taking brodalumab, your doctor will monitor you for signs of infection.
Suicidal or agitated behaviour: People with psoriasis appear to be at an increased risk of suicidal behaviour. If you have depression or other mental illness, you may be at an increased risk of mood changes, feeling agitated (restless, anxious, aggressive, emotional, and feeling not like themselves), or wanting to hurt yourself or others. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately.
Vaccines: Live vaccines (e.g., BCG, yellow fever) are not recommended for people taking this medication. Talk to your doctor if you need any vaccinations while taking this medication.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
