Treatments for influenza include a range of medications and therapies that are used in response to disease influenza. Treatments may either directly target the influenza virus itself; or instead they may just offer relief to symptoms of the disease, while the body's own immune system works to recover from infection.^[1]

The main classes of antiviral drugs used against influenza are neuraminidase inhibitors, such as zanamivir and oseltamivir, polymerase acidic endonuclease inhibitors such as baloxavir marboxil, or inhibitors of the viral M2 protein, such as amantadine and rimantadine. These drugs can reduce the severity of symptoms if taken soon after infection and can also be taken to decrease the risk of infection. However, virus strains have emerged that show drug resistance to some classes of drug.
