  • People who have an impaired immune system or who are receiving medications that affect their immunity, as well as their close contacts, such as caregivers or family members.

How to Prevent the Flu

  • Avoid close contact.
  • Stay home when you are sick.
  • Cover your mouth and nose.
  • Clean your hands.
  • Avoid touching your eyes, nose, or mouth.
  • Practice other good health habits such as getting plenty of sleep, exercise, and nutrition.

Treating the Flu

If you do get the flu, your doctor may prescribe antiviral medications such as amantadine, rimantadine, zanamavir, or oseltamivir. These medications are most effective if taken with 2 days of developing the flu, so if you have flu symptoms, see your doctor early. If you have the flu, your doctor may also recommend plenty of rest, lots of liquids, and no alcohol or tobacco. Acetaminophen may be recommended but aspirin should not be given to children or teen-agers who develop flu symptoms, especially fever. See your pediatrician if your child has flu symptoms.

The formulary for these, as stated by CVS/Caremark (my pharmacy benefits provider), covers all test strips, lancets, and control solutions. I dutifully get my doctor to write up prescriptions for all of my testing needs, submit...
