Influenza is an acute respiratory infectious disease caused by influenza virus. It is common in winter and spring every year. Local symptoms are mild and systemic symptoms are severe. For those who have been diagnosed with influenza or have flu like symptoms such as persistent fever, headache, aching limbs, cough, runny nose, etc., they can take oseltamivir granules orally. Osltamivir granules are antiviral drugs for influenza virus. They inhibit further replication of influenza virus and inactivate influenza virus by inhibiting the neuraminidase activity of influenza virus. The best effect is to use it within 48 hours of onset, twice a day, two milligrams per kilogram of body weight, for five consecutive days. During the epidemic period of influenza, this drug can also be used to prevent the occurrence of influenza once a day for 10 consecutive days for infants about one year old who are usually poor in constitution and immune function. The adverse reaction of this product is mild, and some children may have gastrointestinal symptoms, which will not affect the use.
