Flu Shot Alternatives
One alternative to a flu shot is to get FluMist, the nasal spray flu vaccine which is often in good supply even when there are shortages of flu shots. There are some limitations though, including that it can only be given to healthy people from the ages of 2 to 49 years, so that leaves out younger children, the elderly and others at high risk for flu complications. It also can be more expensive than a flu shot and not all insurance companies pay for it, so check with your insurance company and doctor to see if FluMist is a good alternative for you. The price was reduced in recent years, so it may be more affordable for more families.Since FluMist is thimerosal free, it is also a good alternative for parents who were avoiding getting a flu shot because of worries over its having thimerosal. It still shouldn't be given to kids with egg allergies though.
Antiviral Drugs
In addition to flu immunizations, antiviral drugs can also be used to prevent the flu. These medications include:- amantadine (Symmetrel)
- rimantadine (Flumadine)
- oseltamivir (Tamiflu)
Other people may just want to take them after being exposed to someone with the flu. For example, if one of your kids is diagnosed with the flu, it might be worthwhile to get a prescription for one of the antiviral drugs for all other household members who didn't get a flu immunization so that they don't catch it too.
Tamiflu and another medication called zanamivir (Relenza), can also be used as a treatment for the flu to 'shorten the time a person infected with influenza feels ill' if they are started within 1-2 days of your becoming sick.
Avoiding the Flu
The last alternative, which isn't always practical, is simply trying to avoid people who are sick with the flu. Or at least try and get everyone around you or your child to get vaccinated against the flu. See our guide to Avoiding Getting Sick with the Flu for more information.
