What Is Cuvitru Used For?

Cuvitru is an immunoglobulin solution that contains human antibodies to help boost your immune system when your body doesn’t produce enough antibodies naturally.

Primary Uses

Cuvitru is used in patients who do not have enough antibodies in their blood. It serves as antibody replacement therapy to raise antibody levels in your blood to normal levels.

How It Works

Immunoglobulins (antibodies) are naturally found in healthy people’s blood and are part of the immune system – your body’s natural defenses. They help your body fight infections. If you don’t have enough antibodies, you may not be able to fight off infections effectively.

Good to know: Cuvitru is made from human blood plasma with stringent safety measures including careful donor selection, testing, and viral inactivation processes to minimize infection risk.

How to Take Cuvitru

Cuvitru must be infused under the skin (subcutaneously) using either an infusion pump or manual administration with a syringe. Your doctor will determine the appropriate method and rate for you.

Dosage Instructions

The recommended dose and schedule will be established by your doctor based on your individual needs and response to treatment. Ensure you are adequately hydrated before administration. Your doctor will start treatment slowly and monitor you during first infusions. Once trained, you may be able to administer at home. For manual administration, the recommended infusion rate is approximately 1-2 mL per minute. Doses over 30 mL may be divided according to your preference.

What If You Miss a Dose?

Do not infuse a double dose to make up for a missed dose. If you think you have missed a dose, speak to your doctor as soon as possible.

Important: Never double dose to make up for missed doses. Always wash your hands and use sterile technique during preparation and injection.
