1. What is Viseltam and what is it used for
- Viseltam is used in adults, adolescents, and children over 6 years of age, with a body weight of more than 40 kg, for the treatment of influenza. It can be used when influenza symptoms appear and when it is known that the influenza virus is circulating in the environment.
- Viseltam may also be prescribed to adults, adolescents, and children over 6 years of age, with a body weight of more than 40 kg, for the prevention of influenza. Each case is considered individually - for example, if the patient has had contact with a person with influenza.
- Viseltam may be prescribed to adults, adolescents, and children over 6 years of age, with a body weight of more than 40 kg, as a preventive treatmentin exceptional circumstances, such as during a global influenza epidemic (pandemic), when the seasonal influenza vaccine does not provide sufficient protection.
Viseltam contains oseltamivir, which belongs to a group of medicines called "neuraminidase inhibitors". These medicines prevent the spread of the influenza virus in the body. They help to alleviate symptoms or prevent their occurrence in the case of influenza virus infection.
Influenza is an infectious disease caused by the influenza virus. Influenza symptoms include sudden onset of fever (above 37.8°C), cough, runny or stuffy nose, headache, muscle pain, and often extreme fatigue. Such symptoms can also be caused by infections other than influenza. True influenza infection occurs only during annual outbreaks of the disease (epidemics), when the influenza virus spreads in the local environment. Outside of epidemic periods, influenza-like symptoms are usually the result of developing another disease.
