Yes — Cost Plus Drugs lists Oseltamivir Phosphate at roughly $0.283 per unit, a published price with no membership card or coupon involved. See the three-price comparison above for how that stacks up against discount-card pharmacies.

We found Canadian pricing for Oseltamivir Phosphate starting near $1.96 per tablet in USD terms. That's before any shipping charge, which the table above breaks out separately.

Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.

Oseltamivir is an antiviral medication approved by the FDA to treat uncomplicated influenza (the flu). It is prescribed for individuals aged two weeks and older who have experienced flu symptoms for fewer than 48 hours. The drug works by blocking the virus's ability to reproduce and spread from infected cells, thereby reducing the overall viral load in the body. It is often recommended for patients at higher risk of flu-related complications, such as pneumonia. While it can also be used for flu prevention in certain situations, it is not a substitute for the annual influenza vaccine. For treatment, the typical dosage is one 75mg capsule taken twice daily for five days.

Common side effects of Oseltamivir can include nausea, vomiting, headache, diarrhea, and general pain. Although rare, some individuals may experience mental or mood changes, such as confusion, agitation, or hallucinations. Allergic reactions, while also uncommon, are possible and may present as a skin rash, itching, hives, or difficulty breathing. If you experience signs of a severe allergic reaction or a serious skin reaction, seek emergency medical attention. It's always advisable to discuss any concerns about potential side effects with your doctor or pharmacist before starting the medication.

Oseltamivir is the generic name for the active ingredient found in the brand-name drug Tamiflu. Multiple generic manufacturers, including Macleods, Alembic, and Lupin, produce Oseltamivir. Both the generic and brand-name versions are available by prescription.
