Plants have been used in traditional medicines for treating bacterial, viral and fungal infections. Some have shown potential to prevent and treat viral infections by activating the immune system to target virally infected cells. However, always consult a health-care provider before self-medicating with herbal supplements as they are not regulated by the U.S. Food and Drug Administration.
Antivirals are medicines that help fight viruses like the flu and cold. These can be either modern medicine that a doctor prescribes or alternative medicines, usually in the form of herbs. Herbal antivirals can be taken without prescription and will either help prevent viruses or will work to reduce the duration of a cold or flu.
Antiviral chemoprophylaxis is a term used to describe the use of antiviral medications to prevent viral infections such as the flu. The technique is sometimes used to protect health workers and others at high risk for virus exposure.
Certain medications are known to cause hepatotoxicity, which TheBody.com defines as "a general term for liver damage." Antiviral drugs, used to treat viruses such as HIV, smallpox, herpes simplex and human papilloma, may have hepatotoxic side effects.
Viruses are a parasitic nucleus of DNA surrounded by protein and other organic compounds. A majority of biologists consider viruses to be nonliving creatures, despite the organic composition of the parasites. Viruses are unable to reproduce without using essential components located in the host. The inability of viruses to reproduce without a host is what sets them apart from living organisms.
The goal of antiviral drugs is to either kill a virus or manage it in such a way that unpleasant symptoms are removed. Your body is sophisticated enough to cooperate with the drugs in your system to target a specific area; in this case, it is the virus that needs to be fought. Some viruses are too strong for the immune system to fight alone, thus the reason why antiviral medications are prescribed.
Antiviral agents are drugs that are designed to interrupt the reproduction of viruses. They help the body have a fighting chance against viral illness. Common viral illnesses include colds, the flu, and HIV/AIDS.
Antiviral drugs fall into the classification of drugs used specifically to treat infections caused by virus. They are part of the antimicrobials family, which is a larger group of drugs that includes antibiotics, antifungal and anti-parasitic medicines. Antiviral drugs are formulated not to destroy pathogens but rather to stop them from developing.
Antiviral drugs are those used in the treatment of conditions caused by viral pathogens. They are somewhat like antibiotics used in the treatment of bacterial conditions. However, it is important to note that, since viruses are not "alive" (as are bacteria) antiviral drugs do not "kill" viruses, but interrupt their cycle of replication and infection at several different stages. Antiviral drugs currently are only used in the treatment of a limited number of viruses.
