Oseltamivir (Tamiflu) prescription online: new course or renewal
Oseltamivir (Tamiflu) is a short course, so a new flu illness or exposure this season usually needs a new evaluation, not a renewal. A licensed doctor can review your symptoms and history online and send a prescription when it's appropriate.
What is oseltamivir (generic Tamiflu)?
Oseltamivir (Tamiflu) is a prescription antiviral medication used to manage influenza A and B infections. It blocks an enzyme the flu virus needs to spread, so new virus particles can't leave infected cells. Started within 48 hours of symptoms at the right dose, oseltamivir can make the flu shorter and milder.
New course: For a new flu illness or a recent exposure this season, you can get Tamiflu online.
Renewal: For a preventive course a doctor already started, only in specific high-risk situations.

Is online oseltamivir treatment right for you?
You may be a good fit if your flu symptoms started in the past 48 hours, or later if you're at high risk of complications. A recent flu exposure or a preventive course a doctor already started also counts. Ongoing preventive use is only recommended in specific high-risk situations, so share the clinical reason and your current dose if you're asking for a renewal.
A licensed doctor will review your breathing history and any conditions like asthma or COPD. They'll also check your medications for interactions with oseltamivir. If you have kidney problems, tell the doctor. You may need a lower dose.

Frequently asked questions
Oseltamivir inhibits the neuraminidase enzyme on the surface of influenza A and B viruses. Blocking this enzyme stops new virus particles from leaving infected cells and spreading. That can make the flu shorter and milder.
Oseltamivir is most effective when started within 48 hours of flu symptom onset. Starting treatment early can reduce the duration of illness by about one day and may lower the risk of serious complications such as pneumonia. People at high risk of complications should still be treated even after 48 hours.
For treatment of influenza in adults, the standard dose is 75 mg taken twice daily for 5 days. For prevention after exposure, the dose is typically 75 mg once daily for 10 days. A licensed doctor may adjust the dose if you have reduced kidney function. See the full oseltamivir dosage chart.
Yes. Oseltamivir is approved to prevent flu after close contact with someone who has it. Longer preventive use, such as during an outbreak, is recommended only in specific high-risk situations and as directed by a doctor. After a single exposure, prevention usually lasts 10 days.
The most commonly reported side effects are nausea and vomiting. Taking oseltamivir with food can help reduce stomach upset. Less common side effects include headache, diarrhea, and dizziness. Rare but serious neuropsychiatric events such as confusion or unusual behavior have been reported, particularly in children and adolescents. Read how long oseltamivir stays in your system after your last dose.
No. The yearly flu vaccine is the first line of prevention and lowers your risk of getting the flu. However, vaccine effectiveness varies by season, and oseltamivir remains an important treatment option if you do become infected. The vaccine and oseltamivir can be used together.
Check the expiration date first, and talk to a licensed doctor before taking it. Leftover capsules may not be a full course or the right dose, and a new flu illness usually needs a new evaluation.
Yes, if a licensed doctor finds it appropriate. For adults, post-exposure prevention is usually 75 mg once daily for 10 days. Each adult in the household needs their own evaluation. Children under 18 should see their own doctor.
Take it as soon as you remember, unless your next dose is due within 2 hours. In that case, skip the missed dose and keep your usual schedule. Read more about what to do if you missed a dose of oseltamivir.
