1. What is Oseltix and what is it used for
- - Oseltix is used in adults, adolescents, and children over 6 years of age and weighing more than 40 kg for the treatment of influenza. It can be used when flu symptoms appear and when it is known that the influenza virus is circulating in the environment.
- Oseltix may also be prescribed for adults, adolescents, and children over 6 years of age and weighing more than 40 kg to prevent influenza. Each case is considered individually - for example, if the patient has been in contact with someone with the flu.
- Oseltix may be prescribed for adults, adolescents, and children over 6 years of age and weighing more than 40 kg as preventive treatmentin exceptional circumstances, such as during a global influenza epidemic (pandemic), when the seasonal influenza vaccine does not provide sufficient protection.
Oseltix 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 alleviate symptoms
or prevent their occurrence in case of influenza virus infection.
Influenza is an infectious disease caused by a virus. Influenza symptoms often include sudden onset of
fever (above 37.8°C), cough, runny or stuffy nose, headache, muscle pain, and extreme fatigue. Such symptoms can also be caused by other infections. 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, flu-like symptoms are usually the result of other diseases.
