Influenza is usually a viral infection, so patients presenting with influenza usually have to apply some antiviral drugs, such as western amantadine, acyclovir, oseltamivir, ribavirin, etc. If the patient’s blood routine suggests high blood count, the patient is considered to need to apply some anti-bacterial drugs such as amoxicillin and azithromycin along with the anti-viral. Besides, some symptomatic supportive therapies are needed, such as cough suppressant and phlegm treatment. Acetylcysteine effervescent tablets, Mucosolvan tablets, loquat, licorice tablets, eucalyptus lemongrass enteric capsules, etc. can be used, all of which have very good cough suppressant and phlegm treatment effects. If the immunity of the patient’s body is very low, you can also choose synergistic immune regulating drugs, such as pidomod and splenamine-based drugs.
