Antiviral drugs play a crucial role in treating viral infections and can significantly reduce the severity and duration of illnesses caused by viruses such as influenza, HIV, and hepatitis. However, the effectiveness and safety of these medications largely depend on the correct dosage. Administering an inadequate or excessive dosage can lead to treatment failure or adverse effects. Therefore, it is essential for both healthcare professionals and patients to be well-informed about antiviral drug dosage.
