Flu & Antibiotics: What You Need to Know

Antibiotics are not effective in treating the flu because the flu is caused by a virus, not a bacteria. Antibiotics only work on bacterial infections.

Antibiotics only treat bacterial infections, whereas the flu is a viral infection.

Viral infections like the flu are not affected by antibiotics. Antibiotics can even be harmful in some cases because they can kill healthy bacteria in the body.

Instead of antibiotics, people with the flu are typically treated with over-the-counter medications like ibuprofen or Tylenol to relieve symptoms like fever, headache, and body aches. Rest, fluids, and good nutrition are also important for helping the body fight the flu.

In some cases, antiviral medications may be prescribed for people with the flu.

Antiviral medications work by interfering with the virus's replication cycle, which can shorten the duration and severity of the illness. Antiviral medications are typically reserved for people who are at high risk of complications from the flu, such as young children, pregnant women, and people with weakened immune systems.

If you think you may have the flu, contact your doctor to discuss the best treatment options for you.
