Let's take a minute to talk about your medication. 

This is Synagis. Synagis helps protect kids who are at high risk for lung problems from a virus called 'RSV'. 

RSV is common; in fact, it infects almost all children by age 2. Usually, RSV simply causes a bad cold. But, it can cause serious lung problems, like pneumonia, in children with certain health conditions. These include children under age 2 who were born prematurely, or who have certain heart or lung problems. Their immune systems may not be strong enough yet to fight RSV. Synagis has antibodies which boost the immune system, and can help avoid serious lung problems. 

RSV has a season when it is the most active. In the United States, the season is usually November through April. Synagis is given just before RSV season starts. And, it must be given again every 28 to 30 days during the season. Synagis is given as an injection, usually into the thigh muscle, by your child's healthcare provider. 

The most common side effects include a fever, rash, or reactions where the shot was given, like redness, swelling or warmth. These are normal if they are mild, and should go away. 

As with any medicine, more serious side effects could occur. With Synagis, these include allergic reactions, unexplained bruises, or tiny red spots on the skin. Call the doctor right away if you notice these or other unusual changes to your child's body. 

For best results protecting your child from RSV, be on time for every dose.  Also, read the Patient Package Insert for full information.
