What types of doctors treat the flu?
Individuals with mild flu symptoms may not require the care of a physician unless they are a member of a high-risk group as described above. For many individuals, treatment is provided by their primary care physician or provider (including internists or family medicine specialists and physician assistants and other primary caregivers) or pediatrician. Complicated or severe flu infections may require consultation with an emergency-medicine physician, critical care specialist, infectious-disease specialist, and/or a lung specialist (pulmonologist).
What medications treat the flu?
The CDC published the following guidance concerning antiviral drugs:
Antiviral medications with activity against influenza viruses are an important adjunct to influenza vaccine in the control of influenza.
- Influenza antiviral prescription drugs can be used to treat influenza or to prevent influenza.
- Oseltamivir, zanamivir, and peramivir are chemically related antiviral medications known as neuraminidase inhibitors that have activity against both influenza A and B viruses.
The following are the CDC recommended antiviral medications for the treatment of influenza (flu) for the 2016-2017 season are as follows: oral oseltamivir (Tamiflu), inhaled zanamivir (Relenza), and intravenous peramivir (Rapivab). See Table 1 below for details about utilizing these drugs in adults and children.

Over-the-counter medications that may help reduce symptoms of congestion (decongestants), coughing (cough medicine), and dehydration include diphenhydramine (Benadryl), acetaminophen (Tylenol), NSAIDs (Advil, Motrin, Aleve), guaifenesin (Mucinex), dextromethorphan (Delsym), pseudoephedrine (Sudafed), and oral fluids. Aspirin may be used in adults but not in children.
Antibiotics treat bacterial infections, not viral illnesses like the flu.
Individuals with the flu may also benefit from some additional bed rest, throat lozenges, and possibly nasal irrigation; drinking fluids may help prevent symptoms of dehydration (for example, dry mucus membranes and decreased urination).
