Tamiflu (Oseltamivir) For Flu

Active ingredient: Oseltamivir phosphate
Drug class: Antiviral, Neuraminidase Inhibitors
Company name: Hoffmann La Roche Inc

Tamiflu (Oseltamivir phosphate) is an antiviral medicine effective against influenza types A and B. When started during the first 2 days of the illness, Oseltamivir speeds recovery and reduces the duration of flu by 1.5 days.

It is also used for the prevention of influenza. Tamiflu can prevent the flu as long as you continue taking the prescription.

How effective is Tamiflu?

According to a major review of over 50 studies published in 2006, Tamiflu is effective against the flu in about 60% of cases.

Oseltamivir phosphate is active against both influenza types A and B. The drug can reduce the severity and duration of illness or help to reduce the chance of getting the flu. The sooner Tamiflu is started after flu symptoms onset, the more effectively drug works.

As the flu virus penetrates into the body, it forms new copies of itself and spreads from cell to cell. Tamiflu fights the virus by preventing the release of new copies from infected cells. Oseltamivir works by blocking a key viral enzyme, neuraminidase, which is involved with viral replication.

Tamiflu may not prevent the development of immunity - when used as prophylaxis, oseltamivir can prevent illness while permitting sub-clinical infection and development of protective antibody against circulating influenza viruses.

What are the disadvantages and side effects?

About 10 - 15% of persons experience nausea and vomiting.
There is no such thing as generic Tamiflu. Being available exclusively as brand medication made by Hoffman La Roche it is pretty expensive.
Limited production capacity. The manufacturing process for oseltamivir is complex and time-consuming, involving a complex, 10-step process that takes approximately 6-8 months.
To be effective as much as possible for flu prevention, the drug must be taken each day during the influenza outbreak, not just the peak period. This makes use of Tamiflu as prophylaxis questionable and potentially very expensive.
Timing is very critical when used for flu treatment. The drug should be started within 2 days of the start of symptoms to be effective. When you need the prescription for Tamiflu and the speed of getting the medication is important you can order online with Next Day delivery.
Benefits may be limited when used as treatment - oseltamivir can reduce the duration of uncomplicated influenza by approximately one day. The drug's effectiveness in preventing serious influenza complications is unclear.
