What are antiviral drugs?

Antiviral drugs are those medications that are prescribed for treating viral infections. These help to reduce the growth of viruses causing the infection. According to the Center for Vaccine Awareness and Research at Texas Children’s Hospital, "Antivirals help fight the flu by binding to an enzyme in the virus so the infectious parts of the virus, called virions, cannot be released,”. Antivirals are commonly used to treat infections caused by HIV, herpes viruses, hepatitis B and C viruses, and influenza A and B viruses. You can also search for antiviral drug treatment online before taking antiviral medicine.


How Do Antivirals work?

Antivirals work in a very unique way which is ceasing the growth of the virus. Antivirals are not used against bacteria but viral infections. By ceasing the development of the fungal/viral/parasitic infection the antiviral stops the growth and slowly the body eradicates the infection. One of the most effective antivirals found is eucalyptus as well as Australian tea trees which known to be super effective. An amazing phenomenon seen in antivirals is the process of binding the enzyme which puts a barrier for the infection to spread. Time to time consumption of antivirals can help the immune system to fight against the infection as the infection/ virus is unable to advance to more cells.

Uses of Antivirals

Antivirals may seem handy to use but the complex nature of diseases and the variations in them makes it hard for antivirals to tackle them. Viruses are mostly parasitic in nature as they do not use their energy to survive. They use the existing cells in the body and replicate rapidly. The Antivirals available in today's world are limited to few infections because ceasing the growth of a virus as well as protecting the host cells need intense research and safety.

Few diseases for which antivirals are available are as follows:


There are various types of Herpes. Herpes zoster (shingles) is an infection caused by the virus that causes chickenpox. Genital herpes is an infection caused by the herpes simplex virus (HSV). Medications do not cure the infection but help with reducing the severity of the condition. Each type of herpes has different medications, depending upon the severity of the disease the doses are provided to reduce the Virus.

Medications for Herpes

Acyclovir is the most recommended medicine for the treatment of herpes and is easily affordable. It was the first antiviral experiment and was found using hit and try method by the medical researchers. Acyclovir is available in form of liquid, as eye drops for eye infections, as an injection. 

Herpesviruses have different degrees of susceptibility with HSV type 1 being most susceptible, followed by HSV type 2 and VZV.


Influenza is caused by influenza viruses and is referred to as the flu. There are vaccines for influenza in addition to various Antiviral drugs. It is necessary to take medications at the right time to prevent further complications as the influenza viruses routinely spread in people. 

Medicines for Influenza


The most effective treatment for influenza, amantadine has been recommended and prescribed by doctors as it starts affecting within a day.

Relenza (zanamivir)

Amantadine and rimantadine have similar effectiveness but neurologic impacts are less severe and frequent with rimantadine.

Tamiflu- Approved to treat type A and B Influenza, Tamiflu is used for acute and uncomplicated influenza.

With and through time we have witnessed numerous cures and medicines that are widely available today but were not in the past. However, finding generic medicines in this world of convenience is still a hurdle. Today antiviral drugs have been invented but are not available to people on time due to lack of genuine availability. A perfect spot that you can go to is  Generic Medicine as it is available 24/7 to eliminate this hindrance and is helping us with antiviral drug treatment online.
