Before giving you child Voxzogo
Before you give your child Voxzogo, tell your child’s healthcare provider about all your child’s medical conditions, including if they:

- are pregnant or plan to become pregnant. It is not known if Voxzogo will harm your child’s unborn baby.

How should I take Voxzogo
- See the detailed Instructions for Use that comes with your child's prescription for instructions about the right way to store, prepare, and give Voxzogo injections at home.
- Voxzogo is given as an injection under the skin (subcutaneous or SC). Inject Voxzogo 1 time every day, at about the same time each day.
- If your child’s healthcare provider decides a caregiver can give the injections of Voxzogo at home, your child’s caregiver should receive training on the right way to prepare and inject Voxzogo. Do not try to inject Voxzogo until you have been shown the right way by your child’s healthcare provider or nurse.
- Your child’s healthcare provider will tell you how often you should give Voxzogo. If your child misses a dose of Voxzogo, it can be given within 12 hours of the scheduled time of injection. If more than 12 hours have passed, do not give the missed dose. Give the next daily dose according to your child’s usual schedule.
- Your child should eat a meal and drink about 8 to 10 ounces of fluid within 1 hour before injection.
- In case you are not sure when to inject Voxzogo, call your child’s healthcare provider or pharmacist. Do not give Voxzogo more often than as directed by your child’s healthcare provider.
- Your child’s dose depends on his or her body weight. Your child’s healthcare provider will tell you which strength of Voxzogo to use and how much to give your child.
- Your child’s healthcare provider will monitor your child’s growth and instruct you on when your child should stop Voxzogo if they determine that your child is no longer able to grow. Stop giving Voxzogo to your child if instructed by your child’s healthcare provider.
