  • Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Manage your symptoms:

  • Rest and sleep: Rest and sleep may help you get better faster.

  • Drink plenty of liquids: Ask your healthcare provider how much liquid to drink each day and which liquids are best for you. This can help prevent dehydration.

Prevent the spread of H1N1 influenza:

  • Wash your hands often: Use soap and water. Use gel hand cleanser when there is no soap and water 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 so you do not spread germs from your hands.

  • Clean shared items: Clean table surfaces, doorknobs, and light switches with a germ-killing cleaner. 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 face mask: Wear a mask over your mouth and nose if you have H1N1 influenza or are near anyone who has H1N1 influenza. Ask where to buy single-use masks.

  • Stay home if you are sick: Stay away from others as much as possible while you recover.

  • Influenza vaccine: This vaccine helps prevent influenza (flu). Everyone older than age 6 months should get a yearly influenza vaccine. Get the vaccine as soon as it is available, usually in October or November each year.
