How does this medication work? What will it do for me?
Bimekizumab belongs to the class of medications called immunomodulators. It is used to treat moderate-to-severe plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis in adults. When people have any of these conditions, their bodies overproduce certain proteins called interleukins (IL). Increased levels of these proteins cause inflammation which can result in itching, pain, and scaling skin. Bimekizumab blocks the action of 2 types of interleukin-17, (IL-17A and IL-17F), reducing the symptoms of plaque psoriasis.

What form(s) does this medication come in?
Each mL of clear-to-opalescent, pale-brown-to-light-yellow, preservative-free, sterile solution, contains 160 mg of bimekizumab. Nonmedicinal ingredients: acetic acid, glycine, polysorbate 80, sodium acetate trihydrate, and water for injection.

How should I use this medication?
The recommended dose of bimekizumab is 320 mg injected subcutaneously (under the skin), every 4 weeks for the first 16 weeks. Each 320 mg dose is made up of 2 separate injections of 160 mg. After the first 16 weeks, 320 mg of bimekizumab is given every 8 weeks. A full dose consists of 2 injections (of 160 mg each), given one right after the other. Inject the second syringe at least 3 cm (1 inch) away from the first injection.
When treating psoriatic arthritis or ankylosing spondylitis, the recommended dose is 160 mg injected subcutaneously, every 4 weeks.
This medication is administered by subcutaneous injection in the thigh, upper arm, or abdomen. It is important to change the injection site you're using, rotating between sites, to reduce the risk of fat wasting at the injection site. Avoid injecting into areas that are tender, bruised, or affected by psoriasis.
The solution should be clear-to-slightly milky and colourless-to-pale-brown-yellow. If the solution is discoloured or contains flakes or large particles, do not use the contents of the prefilled syringe. Instead, use a fresh syringe.
