Synagis Usage
- Synagisis is given as a monthly injection, usually in the thigh (leg) muscle, by your child’s healthcare provider. Your child’s healthcare provider will prescribe the amount of Synagisis that is right for your child (based on their weight).
- Your child’s healthcare provider will give you detailed instructions on when Synagisis will be given.
- “RSV season” is a term used to describe the time of year when RSV infections most commonly occur (usually fall through spring in most parts of the country). During this time, when RSV is most active, your child will need to receive Synagisis shots. Your child’s healthcare provider can tell you when the RSV season starts in your area.
- Your child should receive their first Synagisis shot before the RSV season starts to help protect them before RSV becomes active. If the season has already started, your child should receive their first Synagisis shot as soon as possible to help protect them when exposure to the virus is more likely.
- Synagisis is needed every 28-30 days during the RSV season. Each dose of Synagisis helps protect your child from severe RSV disease for about a month. Keep all appointments with your child’s healthcare provider.
- If your child misses an injection, talk to your healthcare provider and schedule another injection as soon as possible.
- Your child may still get severe RSV disease after receiving Synagisis; talk to your child’s healthcare provider about what symptoms to look for. If your child has an RSV infection, they should continue to get their scheduled Synagisis injections to help prevent severe disease from new RSV infections.
- If your child has certain types of heart disease and has corrective surgery, your healthcare provider may need to give your child an additional Synagisis injection soon after surgery.
