Anti Viral

Anti Viral are prescribed drugs used to treat viral infections. They are most effective when administered early in the infection and are used to prevent the virus from replicating.

Examples:

• Oseltamivir (Tamiflu) Anti Viral: Used to treat influenza (flu).
• Acyclovir (Zovirax): Treats herpes simplex virus (HSV) infections, including cold sores and genital herpes.
• Remdesivir (Veklury): Used for treating COVID-19.
• Valacyclovir (Valtrex): Treats herpes simplex, shingles, and cold sores.

1. Over-the-counter (OTC) Antivirals

These are less potent than prescription antivirals and are often used for mild viral infections, such as cold sores or minor flu symptoms.

Examples:

• Docosanol (Abreva): Used to treat cold sores caused by HSV.
• Penciclovir (Denavir): Also for cold sores.

1. Natural Antivirals

Some natural compounds and herbs are believed to have antiviral properties, though their effectiveness can vary.

Examples:

• Elderberry: Thought to help reduce flu symptoms.
• Garlic: Known for immune-boosting properties.
• Echinacea: Used to prevent or shorten the duration of colds.
• Vitamin C: Although not directly antiviral, it is commonly used to support the immune system.

1. Preventative Measures

• Vaccines: Vaccines like the flu vaccine, MMR vaccine (measles, mumps, rubella), and the COVID-19 vaccine are some of the most effective ways to prevent viral infections.
• Hygiene Practices: Handwashing, wearing masks, and social distancing can help prevent the spread of viruses.

1. Antiviral Actions:

The ways antivirals work include:

• Inhibiting Virus Entry: Preventing the virus from entering host cells.
• Inhibiting Virus Replication: Blocking the ability of the virus to replicate within cells.
• Preventing Virus Release: Blocking the release of new viral particles from infected cells.
