Treatment for influenza
may include any of the following:
- 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 , such as ibuprofen, help decrease swelling, pain, and 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.
- Antivirals help fight a viral infection.
Manage your symptoms:
- Rest as much as you can to help you recover.
- Drink liquids as directed to help prevent dehydration. Ask how much liquid to drink each day and which liquids are best for you.
Prevent the spread of the flu:
- Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food. Use gel hand cleanser that has 60% alcohol, when soap and water are not available. Do not touch your eyes, nose, or mouth unless you have washed your hands first.
- Cover your mouth when you sneeze or cough. Cough into a tissue or the bend of your arm. If you use a tissue, throw it away immediately and wash your hands.
- Clean shared items with a germ-killing cleaner. Clean table surfaces, doorknobs, and light switches. Do not share towels, silverware, and dishes with people who are sick. Wash bed sheets, towels, silverware, and dishes with soap and water.
- Wear a mask over your mouth and nose if you are sick. The face mask may help protect others from becoming infected with the flu. Wear the mask when in common areas of your home or if you seek care with a healthcare provider.
- Stay away from others if you are sick. Stay at home until 24 hours after your fever and symptoms are gone.
- Influenza vaccine helps prevent influenza (flu). Everyone older than 6 months should get a yearly influenza vaccine. Get the vaccine as soon as it is available, usually in September or October each year.
