Certainly if you get flu like symptoms such as a cold, fever then it is appropriate to take the usual anti-cold and fever lowering medication. If the illness goes away in a few days, one should rest for an additional day and then resume the normal life. Please keep in mind that both the common seasonal flu and swine flu have the same manifestations to start with.
Please also remember that the vast majority of what is technically swine flu just has a very mild course and persons usually recover even without treatment. They do however develop immunity. What is important is not whether they had Swine flu or common influenza, what is important is that in the vast majority of cases there is an uneventful recovery. Further specific anti-viral treatment is only indicated if the condition worsens and other manifestations occur.
