I catch flue approxemtly two times a year with 5-6 months in between. the question is should i change the type of antibiotics taken every time?

Influenza: If you have influenza you should not be taking antibiotics unless you develop secondary bacterial complications. There are antiviral meds available if you are diagnosed early in the course.

No Antibiotics !: If you have the flu hydrate well w water, herbal teas, soup or juice. Drink sufficiently to have pale to light yellow urine. You can use pain relievers like tylenol (acetaminophen) or nsaid’s. Rest a lot! in some situations antiviral medications (tamiflu, relenza, flumadine) may be prescribed within the first couple of days of symptoms to hasten healing or they can be used after flu exposure to prevent illness.
