Antivirals are medications specifically designed to treat viral infections. Unlike antibiotics, which target bacteria, antivirals work by inhibiting the growth and replication of viruses. They can be used to manage various viral illnesses, including influenza, HIV, and herpes. These drugs can help reduce the severity and duration of symptoms, making it easier for the body to recover. Some antivirals are taken as pills, while others may be administered through injections or infusions. It's important to use antivirals as prescribed, as misuse can lead to resistance and reduced effectiveness.
