Antivirals are medications used to treat viral infections by preventing the replication and spread of viruses. Synonyms for antivirals include antiviral agents, antiviral drugs, antiviral medications, antiviral therapy, and antiviral treatments. These terms are often used interchangeably to describe drugs and treatments that are designed to target specific viral infections, including HIV, hepatitis C, influenza, and herpes. While antivirals are an essential tool in the fight against viral infections, they may have side effects and are not always effective in treating all viral infections. Therefore, it is essential to use antivirals under the guidance of a healthcare professional to ensure that they provide the intended benefits without causing harm.
