Manage a concussion:
Usually no treatment is needed for a mild concussion. Concussion symptoms usually go away within about 10 days, but they may last longer. The following may be recommended to manage your symptoms:
- Rest from physical and mental activities as directed. Mental activities are those that require thinking, concentration, and attention. You will need to rest until your symptoms are gone. Rest will allow you to recover from your concussion. Ask your healthcare provider when you can return to work and other daily activities.
- Have someone stay with you for the first 24 hours after your injury. Your healthcare provider should be contacted if your symptoms get worse, or you develop new symptoms.
- Do not participate in sports and physical activities until your healthcare provider says it is okay. They could make your symptoms worse or lead to another concussion. Your healthcare provider will tell you when it is okay for you to return to sports or physical activities. Ask for more information about sports concussions.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- NSAIDs help decrease swelling and pain or fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
Prevent another concussion:
- Wear protective sports equipment that fits properly. Helmets help decrease your risk for a serious brain injury. Talk to your healthcare provider about ways you can decrease your risk for a concussion if you play sports.
- Wear your seatbelt every time you travel. This helps to decrease your risk for a head injury if you are in a car accident.
