Note: You should not be left alone after a concussion. If no adult can stay with the injured person, let the doctor know.

Have someone call 911 or your emergency number if you can't fully wake up or have a seizures or convulsions.

The first 48 hours

Don’t take medicine unless approved by your healthcare provider. Try placing a cold, damp cloth on your head to help relieve a headache.

  • Ask the doctor before using any medicines.

  • Don't drink alcohol or take sedatives or medicines that make you sleepy.

  • Don't return to sports or any activity that could cause you to hit your head until all symptoms are gone and your doctor says it's OK. A second head injury before fully recovering from the first one can lead to serious brain injury.

  • Don't do activities that need a lot of concentration or a lot of attention. This will let your brain rest and heal faster.

  • Return to regular physical and mental activity as directed with your doctor's OK.

For the first day or two, it may be best not to sleep for long periods of time without being checked for alertness. Follow the doctor’s instructions.
