Influenza · Tamiflu (oseltamivir) · Same-day evaluation
Sudden fever, body aches, chills, headache, and a dry cough usually mean influenza. Antivirals work best within 48 hours of symptom onset, so timing matters. A licensed clinician reviews your symptoms, orders flu/COVID testing when it will change treatment, and sends oseltamivir (Tamiflu) or baloxavir (Xofluza) to your pharmacy when it's appropriate.

Oseltamivir (Tamiflu) and baloxavir (Xofluza) shorten flu by about a day and lower complication risk — but only when started early. Booking today rather than waiting out the weekend is the whole game.
They overlap heavily. Your clinician sorts the pattern, orders combined flu/COVID/RSV PCR or rapid strep when the result would change treatment, and treats what you actually have.
Pregnancy, asthma or COPD, diabetes, heart disease, immunosuppression, and age 65+ raise the stakes. Antivirals are recommended for these groups even past 48 hours.
Yes. If your symptoms and timing fit influenza, a licensed clinician can e-prescribe oseltamivir (Tamiflu) to your pharmacy the same day. The standard adult course is 75 mg twice daily for 5 days.
Within 48 hours of the first symptom is the target — that's when Tamiflu shortens illness and reduces complications the most. Past 48 hours it's still recommended for high-risk patients and anyone getting sicker rather than better.
Flu hits suddenly with fever, body aches, chills, headache, and exhaustion. A cold builds gradually and stays mostly in the nose and throat — runny nose, sneezing, mild sore throat, rarely a real fever. See our flu vs. cold comparison for a side-by-side.
Usually from about a day before symptoms start until 5–7 days after — longer in children and immunocompromised patients. A practical rule: stay home until you've been fever-free for 24 hours without fever reducers.
Fever and aches typically break in 3–5 days; cough and fatigue can linger 1–2 weeks. Getting worse after initially improving is a warning sign for pneumonia or a bacterial sinus infection and should be re-evaluated.
Not always. If the clinical picture is clear and you're within the treatment window, testing rarely changes what we do. Testing helps when you're high-risk, when COVID treatment is on the table, or when the diagnosis is genuinely uncertain.
No — influenza is viral. Antibiotics are only added if a bacterial complication develops, such as pneumonia, a sinus infection, or an ear infection.
Trouble breathing, chest pain or pressure, confusion, blue lips, severe dehydration, seizures, or symptoms that improve and then sharply worsen — those need in-person or emergency care, not telehealth.
Yes. If the clinician determines you should stay home, they can issue a dated note through your Ondoc visit.
