Viruses cause diseases in the human body that can be treated with antiviral drugs. Some of them can also be used as a prophylaxis: they protect against infection with viral infections or their spread. Depending on the type of virus or the drug with which it is treated, its effect depends:
- Blocking of receptors so that viruses do not infect healthy cells and do not penetrate into them;
- Improving the men’s immune system to fight the occured disease;
- Reducing the amount of active virus or in other words the viral load.
Antiviral drugs are prescribed in case of chronic or especially dangerous viral diseases, including:
- Swine flu;
- Herpes of the genitals;
- Hepatitis B and C.
Many antiviral drugs are peroral and taken orally. But the range of drugs allows you to choose other forms of medicine:
- Powder for inhalation;
- In the form of ointments and creams.
Depending on the chosen medication, the duration of treatment will change, as well as the amount of antiviral drug that needs to be taken. For example, some intravenous drugs can be taken as one dose per day, which is equal to a week of oral drugs. In chronic diseases, it is usual that patients can take the medicine daily throughout their lives.
