Takhzyro (lanadelumab or lanadelumab-flyo) is an injectable medication used to prevent swelling attacks in the body from a condition called hereditary angioedema (HAE) in adults and children 12 years and older. It's available as ready-to-use vials and prefilled syringes, so it doesn't have to be mixed before use.
Prevention of HAE attacks in people 12 years and older
Takhzyro (lanadelumab) is a monoclonal antibody that's in a group of medications called plasma kallikrein inhibitors. It blocks the activity of a protein in your blood called plasma kallikrein.
Plasma kallikrein is more active in people with hereditary angioedema (HAE) and raises the production of bradykinin, a substance that's responsible for pain and swelling. By lowering plasma kallikrein activity, Takhzyro (lanadelumab) can help prevent pain and swelling attacks in people with HAE.

Takhzyro (lanadelumab) shouldn't be used to treat HAE attacks since it only works to prevent attacks from happening. Continue to keep track of the other medications you use to treat attacks.
If you're using the single-dose vial, make sure you give the injection within 2 hours of drawing up your dose. If you don't use it within 2 hours, you can refrigerate the syringe and use it within 8 hours.
Each Takhzyro (lanadelumab) vial and prefilled syringe are for one time use only. Make sure you use a new vial or syringe for every dose, and throw away any unused medication that's left in a sharps container or puncture-resistant container.
Use a new needle each time you inject Takhzyro (lanadelumab). Don't reuse or share your needles to avoid getting an infection.
Store Takhzyro (lanadelumab) in the refrigerator and in its original packaging until ready to use to protect it from light. Don't freeze or shake the vials or syringes because this can damage the medication.
Takhzyro (lanadelumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Takhzyro (lanadelumab) can cause serious allergic reactions in some people. Get emergency medical help if you experience hives, chest tightness, wheezing, lightheadedness, faintness, fast heartbeat, difficulty breathing, or swelling of the tongue or throat.
The typical starting dose is 300 mg injected under the skin every 2 or 4 weeks.
