Antiviral medicines can be used to shorten the duration and severity of a flu virus, or to prevent more severe complications relating to the virus. Generally, antivirals will be prescribed to help those in at risk groups to deal with the flu virus. These groups include anyone over 65, anyone who is pregnant, anyone with a weakened immune system, anyone with diabetes and anyone with a disease that affects their organs.
Antivirals stop the flu virus from breeding within the body. As such, they won’t cure the flu, but they will stop it from lasting as long and relieve some of the symptoms. They have also been found to be effective in preventing death in patients who’ve been hospitalised with the flu.
