Flu-specific antiviral medications can lessen the severity and shorten the duration of influenza.
Dr. Rehm recommends calling your healthcare provider within the first day or two of illness for maximum impact with flu antivirals.
Antivirals can also reduce the risk of flu complications — like pneumonia.
She notes that several antivirals are being studied for COVID-19, but they’re not available for use at home.

COVID-19 vaccines are currently being studied, but aren’t ready.
Dr. Rehm said it’s important to prevent what we can, especially during a pandemic, and encourages everyone to roll up their sleeves and get a flu shot.
“We know that hundreds of thousands of people are hospitalized because of influenza and it is preventable with vaccine,” she said. “Get the vaccine, it doesn’t take long and that’s one of the best things you can do to protect yourself.”
If you believe you have a serious respiratory infection, like COVID-19 or flu, Dr. Rehm recommends calling your doctor for guidance on testing and treatment options.
