Swine flu (H1N1 influenza) treatment typically involves rest and supportive care. Antiviral medications effective against influenza viruses may also be used. For symptomatic relief, such as fever, headache, and muscle aches (myalgia) associated with influenza, paracetamol or nonsteroidal anti-inflammatory drugs (NSAIDs) can be administered. While there isn't a single specific 'swine flu drug,' treatment focuses on alleviating symptoms and reducing the impact of the illness.

Many individuals with swine flu recover without requiring specific medical intervention, primarily needing symptom management. However, for certain patient groups, such as those with chronic respiratory conditions, a physician might prescribe additional medications to mitigate symptoms.

Four FDA-approved antiviral drugs are sometimes prescribed to reduce the severity of symptoms and the risk of potential complications. These drugs are most effective when administered within 48 hours of symptom onset. It's important to note that influenza viruses can develop resistance to these antiviral medications.

A crucial precaution: due to the rare but severe risk of Reye's Syndrome, children and adolescents with influenza should not be given pain relievers or fever reducers containing acetylsalicylic acid (like aspirin).
