  • What is Synagis?

    Synagis is a medicine used in children to prevent a severe lower respiratory (lung) tract infection caused by a virus called respiratory syncytial virus (RSV). Synagis is administered intramuscularly (injected into the muscle).

  • What is the most important information I should know about Synagis?

    Synagis can cause severe allergic reactions that may result in death if not immediately treated. The doctor will monitor your child closely during treatment with Synagis. Tell your doctor immediately if your child develops a drop in blood pressure, rash, itching, difficult or irregular breathing, closing of the throat, difficulty swallowing, swelling of the lips, tongue, or face, bluish color under his/her fingernails or of the skin, muscle weakness, or unresponsiveness.

    Your child should receive their first Synagis shot before the RSV season starts, which is the time of year when RSV infections most commonly occur (usually fall through spring). If the season has already started, your child should receive their first Synagis shot as soon as possible.

    Your doctor will not use Synagis for treating symptoms of RSV infection if your child already has it. However, your child still needs to get their scheduled Synagis injections to help prevent severe disease from new RSV infections.

    Your child can still get RSV disease after receiving Synagis.
