The CDC and other health experts announced today that people must be very careful with their use of anti-viral medications if they have the swine flu. Experts have said that anti-viral drugs are not necessary for those that are healthy with mild symptoms.
Two of the reasons that these drugs need to be used carefully are that there is a limited supply of the tamiflu drug and there is no need to deplete the supply if you do not need the drug. Tamiflu is also known for having quite the list of side effects, ones that nobody wants to potentially have to deal with if they do not need to.
Beyond these two reasons the most important reason for using the Tamiflu carefully is because that if they are overused they could lose their effectiveness and then we wouldn't have an effective drug for those that truly need the drug.
The H1N1 swine flu virus is already resistant to several influenza drugs and flu viruses are known for being able to mutate, adapt, and build up a resistance to drugs in a short period of time.
If you come down with the swine flu is would be best that you don't take any medication unless it comes absolutely necessary.
