WHY is this medicine prescribed?

Spesolimab-sbzo is used for the treatment of generalized pustular psoriasis (GPP; a skin disease in which pus-filled bumps form on some areas of the body) in adults and children 12 years of age and older weighing at least 40 kg (88 lbs). Spesolimab-sbzo is in a class of medications called monoclonal immunoglobulin G1 antibodies. It works by blocking a certain substance in the immune system that may cause GPP.

HOW should this medicine be used?

Spesolimab-sbzo comes as a solution to inject intravenously (into a vein) over about 90 minutes by a doctor or nurse in a medical office or hospital outpatient clinic to treat a GPP flare. If symptoms of the flare continue, your may receive another dose one week later. Spesolimab-sbzo also comes as a solution (liquid) in a prefilled syringe to inject subcutaneously (just under the skin) by a doctor or nurse or by yourself or a caregiver at home every four weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use spesolimab-sbzo exactly as directed. Do not use more or less of it or take it more often than prescribed by your doctor.

You will receive your first subcutaneous dose of spesolimab-sbzo in your doctor's office. If you will be injecting spesolimab-sbzo subcutaneously to yourself or your child at home or having a caregiver inject the medication for you, your doctor will show you or the person who will be injecting the medication how to inject it. The person who will be injecting the medication should also read the written instructions for use that come with the medication. Be sure to ask your doctor or pharmacist if you have any questions about how to inject the medication.

Spesolimab-sbzo injection may cause a severe reaction during or shortly after the infusion of the medication. A doctor or nurse will monitor you carefully while you are receiving the medication. If you experience any of the following symptoms, tell your doctor immediately: skin redness, itching, hives or rash; swelling of your face, eyelids, lips, mouth, tongue, or throat; mouth sores; lightheadedness, faintness, or dizziness; chest tightness; or shortness of breath.

To give spesolimab-sbzo subcutaneously, follow these steps:

1. Review the manufacturer's instructions for use.
2. Remove spesolimab-sbzo prefilled syringes from the refrigerator and allow to reach room temperature (15 to 30 minutes) without removing the needle cap.
3. Give your dose subcutaneously (just under the skin) into your upper thigh or abdomen (stomach area). Do not inject into areas where the skin is tender, bruised, red, hardened, or scarred.
4. For a complete dose, usually two prefilled syringes are required to be injected, one right after the other.
5. Choose a different injection site for each injection, at least 1 inch away from the other injection sites. Rotate between the upper thigh and abdomen injection sites for each complete dose.
