ℹ️ 1. What Tamiflu is and what it is used for
- Tamiflu is use d for adults, adolescents, children and infants (including full -term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed f or adults, adolescents, children and infants above 1 year of age for preventing flu, on a case -by-case basis – for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (i ncluding full -term newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic ) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors .
These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infecti on caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks ( epidemics ) when flu viruses are spreading in the local community.
Outside epidemic periods, flu- like symptoms are usually caused by a different type of illness.
