In most cases, the flu will go away on its own without the need to see a doctor. But if you have severe flu symptoms or are at risk of serious complications, it’s usually a good idea to seek medical attention. This includes if you are one of the following groups:
- older adults
- young children
- pregnant people
- people with chronic conditions (e.g., asthma, diabetes, heart disease)
- people who are immunocompromised
In otherwise healthy people, flu symptoms should last around 7 to 10 days. If your symptoms don’t improve within this time, or seem to be getting worse, this is also a signal that you should seek medical attention.

|---|---|---|---|
| mild fever | mild fever that isn’t improving | fever of up to 103°F that isn’t improving with medication | fever over 104°F |
| runny or stuffy nose | ear pain | severe sore throat | trouble breathing |
| mild cough | persistent cough | severe ear pain | seizures |

| headache | lingering symptoms | shortness of breath when moving or coughing | blue or gray lips or face |
| body aches | vomiting | vomiting or diarrhea lasting more than 24 hours | confusion |
| fatigue | trouble keeping fluids down | severe weakness | |

| Note: Guidance may differ for people at higher risk of complications, such as young children. If in doubt, seek medical advice. |
When can online care help?
In many cases, the flu is managed with home remedies like plenty of rest, hydration, and over-the-counter medications like ibuprofen (Advil) to reduce your fever. However, in some cases, doctors might prescribe medications that fight the virus, known as antivirals. There are 4 antiviral medications used for the flu:
- oseltamivir (Tamiflu)
- zanamivir (Relenza)
- peramivir (Rapivab)
- baloxavir marboxil (Xofluza)
Online care services, including Optum Perks Online Care, may make getting treatment easier. With these services, you can submit an online form answering a few questions about your symptoms, and a US-licensed healthcare professional will respond soon after to prescribe a treatment plan.
Online care may be a good option if you:
- need advice on symptom management
- want to ask about antiviral medication
- need a doctor’s note for school or work
