- Avoid use of alcohol and illegal drugs.
Avoid activities that might jolt or jar your head—re-injury can lead to more severe or long-term symptoms
- Never return to a sports activity until your doctor has given you permission.
- When you are cleared to do so, gradually return to sports.

- Follow your child's doctor's recommendation of when it is safe to return to contact sports or other activities.
- Do not drink alcohol and drive.
- Do not take medicines that may make you sleepy, especially when driving or using heavy equipment.
