What is this medication for?

Lebrikizumab is used to treat moderate-to-severe atopic dermatitis (eczema). 

Lebrikizumab belongs to a class of medications called biologics. Biologics are genetically-engineered proteins. Lebrikizumab works by blocking the activity of a protein called Interleukin-13 (IL-13). IL-13 levels are higher in people with atopic dermatitis. This medication helps to reduce the inflammation, improve skin condition, reduce itch, redness and scaling. 

Lebrikizumab does not work immediately, and it may take several weeks before you notice any improvement in symptoms.

How should I take or use this medication?

  • Lebrikizumab should be used exactly as prescribed by the doctor.
  • Lebrikizumab comes as a single dose injection in a pre-filled pen.
  • It is administered under the skin as a subcutaneous injection, into the thigh or abdomen, except for 5 cm around the navel (belly button). If somebody else is administering the injection for you, he/she can inject in the back of your upper arm.
  • Rotate the injection site with each injection. Avoid injecting into areas where the skin is tender, damaged, bruised, red, hard, or in an area of skin that is affected by atopic dermatitis or other skin problems.
  • You and your doctor or nurse will decide if you can inject Lebrikizumab yourself. You or your caregiver should receive training on how to inject the medication from your doctor, pharmacist, or specialty nurse before attempting the administration on your own.
  • Do not stop using the medication without discussing it with your doctor. Your doctor will decide how much Lebrikizumab you need and for how long it has to be used for. Stopping Lebrikizumab suddenly may cause the symptoms of your condition to return.
