What is Ebglyss™?
Ebglyss is a biologic medication. The generic name is lebrikizumab-lbkz. It is in a drug class known as a IgG4 monoclonal antibody.
Ebglyss is FDA-approved to treat moderate-to-severe eczema (atopic dermatitis). It is given as an injection under the skin. Patients have the option of taking Ebglyss in a doctor’s office or clinic, or self-administering it at home using an injectable pen or pre-filled syringe.
Ebglyss is used when eczema is not well controlled with topical prescription therapies or when those treatments cannot be used. It treats atopic dermatitis by stopping inflammation on the skin before it can start. The medication can reduce swelling and prevent moderate to severe eczema symptoms.

What is Ebglyss used for?
Ebglyss is a prescription medication used to treat moderate-to-severe atopic dermatitis. It is approved for adults and children 12 years of age or older who weigh at least 88 pounds. Ebglyss is prescribed to people whose eczema is not well controlled with topical corticosteroids (prescription creams or ointments) or who cannot use those types of topical therapies.
How does Ebglyss work for treating atopic dermatitis?
Ebglyss helps treat eczema by targeting the part of the immune system that causes skin inflammation. In people with eczema, the immune system can overreact. It can make too much of a protein called interleukin-13 (IL-13). When there’s excess IL-13, it can cause eczema symptoms such as swelling, raised bumps and itching.
Ebglyss works by attaching to IL-13 and neutralizing it. The medication blocks IL-13 from connecting with a receptor called IL-4Rα. This stops IL-13 from sending the signals that cause inflammation. It helps reduce swelling and severe disease symptoms.
Ebglyss can be used as an add-on treatment, meaning it can be taken alongside other medications your doctor prescribes. In particular, Ebglyss can be used with or without topical steroids.
If you’re prescribed Ebglyss, work together with your doctor on a treatment plan. Follow it closely, as the combination of medications you are prescribed may vary based on the severity of your condition. Regular appointments and open communication with your doctor can ensure your treatment plan is effective. Always follow your doctor’s instructions to get the best results.
Can Ebglyss be used in combination with other medications?
Ebglyss can be used as an add-on therapy, meaning it can be taken alongside other medications your doctor prescribes. It can be taken with or without prescription topical corticosteroids (creams and ointments).
Topical calcineurin inhibitors, which suppress the protein calcineurin that causes skin inflammation, can also be used as an add-on therapy. These are generally reserved for sensitive areas like the face, neck, and genital areas.
Are there any contraindications for using Ebglyss?
Ebglyss should not be used by people who are hypersensitive to lebrikizumab or any ingredients in the medication. If you’ve had allergic reactions to similar prescription medications such as other biologics, talk to your doctor before starting Ebglyss.
What is an IgG4 monoclonal antibody for the treatment of atopic dermatitis?
A monoclonal antibody is a special protein that is a clone, or exact copy, of one type of antibody. The word “mono” means one. Antibodies are proteins that help the body find and fight harmful things, like bacteria or proteins that cause disease.
For Ebglyss, the target protein is interleukin-13 (IL-13), which causes inflammation in the skin. Ebglyss attaches to IL-13 and blocks it. This helps reduce and control inflammation and other eczema symptoms.

What is the dosage for Ebglyss?
Ebglyss dosing to treat atopic dermatitis starts with two loading doses to help build up the medication in your body and work faster.
The loading dose is 500 mg (two 250 mg injections) in the first week and again 2 weeks later. After the loading doses are complete, you take 250 mg (one injection) every 2 weeks until about four months (16 weeks) have passed, or until your symptoms improve. Once your eczema is under control, the maintenance dose is 250 mg every four weeks.
Ebglyss dosing is the same for adults and children ages 12 and older.
How is Ebglyss administered?
Ebglyss can be taken at a doctor’s office or clinic, or it can be self-administered at home by the patient or a caregiver. (The loading dose is typically given in the doctor’s office or clinic.) Your healthcare provider can show you how to use the medication correctly.
Ebglyss is a subcutaneous injection, meaning it’s injected under the skin. Ebglyss comes in two options: a single-dose pre-filled auto-injector pen or a single-dose prefilled syringe.
- Auto-injector pen: This is a device that automatically delivers the medication when you press it against your skin. It may be easier to take if you are uncomfortable with needles.
- Prefilled Syringe: This requires more manual handling, as you need to inject the medication by pressing down on the plunger head.
Children should receive the injections under the supervision of an adult.
The injection sites are the abdomen, thigh, or back of the upper arm. Injection in the back of the upper arm should only be done by a caregiver or healthcare professional. Do not inject within 2 inches of the naval or into areas where the skin is tender, bruised, hard, or affected by eczema symptoms.
Ebglyss can be administered at home by the patient or a trained caregiver. Administering Ebglyss at home offers flexibility in managing treatment. If you’re uncomfortable administering it yourself, talk to your doctor about other options.
Self-administration gives patients the freedom and empowerment to take the medication on their own schedule without going to the doctor’s office every 2-4 weeks. Follow the specific instructions provided by your healthcare provider. Get training from your doctor on how to correctly administer the injection, know the proper injection sites, and use the right technique. Talk with your doctor regularly to make sure you are injecting Ebglyss safely and effectively.
Important things to note when administering Ebglyss:
- Rotate the location of the injection site each time.
- Let Ebglyss warm to room temperature for 45 minutes before the injection.
- Do not use the medicine if it’s cloudy, discolored, or has visible particles.
What are the ingredients of Ebglyss?

Storing Ebglyss at home
Ebglyss needs specific storage conditions to ensure it is safe and effective.
- Store Ebglyss in the refrigerator at 36°F to 46°F (2°C to 8°C).
- You can keep it at room temperature, up to 86°F (30°C), for up to 7 days in its original box. If it’s out for more than 7 days, throw it away. Ensure you mark the box with the date that the medication was removed from the refrigerator so you do not use it past 7 days.

- Shingles (herpes zoster)
Serious side effects of Ebglyss:
While serious side effects are less common, they can happen and may need immediate medical attention. It’s important to be aware of these risks.
Allergic Reactions: Some people who take Ebglyss may have a severe allergic reaction called anaphylaxis.
- Symptoms to watch for: Breathing problems, swelling of the face, mouth, or tongue, hives, severe itching, dizziness, skin rash, or stomach cramps.
