The best flu medicine would be to rest and get plenty of fluids. Most symptoms of flu such as a fever, a runny nose, and blocked sinuses can be managed by acetaminophen and antihistamine medications. However, if the patient has a severe infection or is at a higher risk of complications, the physician may prescribe the following antivirals:
- Oseltamivir
- Zanamivir
- Peramivir
- Baloxavir
Antiviral drugs can shorten the patient’s illness by about a day. They also prevent severe complications of flu such as pneumonia. However, these have a higher incidence of side effects than other antibiotics. Therefore, take them only if really required.
Antiviral drugs should be started within 2 days of getting sick to be effective.
Benefits of taking antiviral drugs include:
- Antiviral drugs shorten the time of being sick by about 1 day if a patient takes them within 2 days.
- They reduce the risk of ear infection, respiratory complications, and hospitalization.
- They reduce the risk of severe flu complications such as pneumonia.
- Early antiviral treatment can reduce the risk of death in a patient who is hospitalized.
How long should antiviral drugs be taken?
The duration for different drugs to treat flu varies as follows:
- Oseltamivir or inhaled zanamivir: A patient should take this drug for 5 days.
- Intravenous peramivir or oral Baloxavir: The doctor gives these drugs for 1 day.
The doctor will usually give oseltamivir to a patient who is hospitalized. Some patients may require more than 5 days of oseltamivir therapy.
Who should take antiviral drugs?
The doctor should immediately start antiviral drugs in a patient who is hospitalized. Moreover, the doctor should also give these to a patient with severe flu symptoms and who is at a high risk of flu complications. Below is a list of health and age factors that likely increases a patient’s risk of flu complications:
- Blood disorders such as sickle cell disease
