Do not start an antibiotic on your own. Antibiotics do not treat colds, flu, or COVID-19, and can cause allergy, diarrhea,
C. difficile infection, and antibiotic resistance. In uncomplicated influenza, antibiotics are not indicated.
CDC flu guidance and
Goldman-Cecil Medicine both support this.
See a clinician
today, particularly if symptoms began within the last
48 hours and you are age 65 or older, pregnant, immunocompromised, or have asthma/COPD, diabetes, kidney disease, heart disease, or severe obesity. You may need assessment for influenza/COVID-19 and prescription antiviral treatment. Flu antivirals work best when started within 2 days; COVID treatment for eligible higher-risk people should also start early.
