Antiviral Medications
Key Points
- Antiviral drugs are used for selected viral infections.
- Core action pattern is inhibition of viral reproduction and, in some therapies, support of host antiviral immune response.
- Antivirals are class-specific and virus-specific; selection depends on infection type.
- Antibiotics do not treat viral infections.
Class Overview
Antiviral therapy targets viral life-cycle steps to reduce viral burden and disease progression. Because viral structure and replication vary by pathogen, antiviral treatment is not one-size-fits-all and should match the suspected or confirmed virus.
Nursing Considerations
- Verify the infection pattern supports antiviral rather than antibacterial treatment.
- Reinforce adherence to prescribed antiviral regimen and follow-up plans.
- Monitor for progression despite treatment and escalate when respiratory or hemodynamic instability appears.
