Tamiflu (oseltamivir)

What is Tamiflu?

Tamiflu contains the active ingredient oseltamivir phosphate, which is a type of medicine called a neuraminidase inhibitor. Tamiflu is used as an oral medication to treat and prevent infection with the influenza virus (flu). Tamiflu, which is manufactured by Roche, has been selected as the medication of choice by the World Health Organisation in the event of an outbreak of a flu pandemic.

How Does Tamiflu Work?

Influenza is a highly contagious virus which relies on a helper chemical on the surface of the virus called neuraminidase, which enables the virus to spread to adjacent cells once it has entered the body. Without the activity of this helper chemical, the virus would be unable to replicate itself and spread to adjacent cells and cause a major infection.

The active metabolite of Tamiflu (oseltamivir) is a neuraminidase inhibitor so it prevents newly formed virus particles leaving the infected cell and spreading, thereby reducing the severity of the infection. Unlike over the counter remedies which only treat the symptoms of flu, Tamiflu actually attacks the virus itself.

How Should I take Tamiflu?

Tamiflu has been shown to reduce the duration of an influenza infection by one day so long as it is taken within 48 hours of the onset of symptoms. It has also been shown to reduce the severity of the symptoms of influenza if taken within this timeframe. The medication is well tolerated and has a good safety profile. Tamiflu is only effective against influenza - it cannot be used for other viral infections.

Tamiflu can be used as a prophylaxis after coming into contact with an infected person. The dosing regimen is slightly different depending on whether the medication is being used as a treatment following the onset of symptoms or if it is being used as a treatment following close contact with an infected person. If you are taking the medication following the onset of symptoms then the adult dose is one capsule twice daily for 5 days. If you are taking Tamiflu as a prophylaxis after coming into contact with an infected person then you will be required to take one capsule per day for 10 days.

Avian Flu

Many people have contacted us in the past about using Tamiflu in the event of a human pandemic of avian flu. The UN has warned that avian flu has the potential to become a global pandemic. Tamiflu has been selected by the World Health Organisation as the medication of choice in the event of an outbreak. Although Avian flu continues to be responsible for deaths in the Far East, there is no evidence of human to human transmission of this H5N1 strain of the influenza virus and it has therefore been eclipsed by news on Swine Flu, which is capable of being passed from human to human.

Swine Flu

Swine Flu is a Type A form of the Influenza Virus, which suggests that it can be serious and can be fatal in certain cases. There have been some fatalities in the UK following an infection with Swine Flu but most people who become infected have mild symptoms and go on to make a full recovery. People who become infected and have a diagnosis of Swine Flu are entitled to free Tamiflu on the NHS. There is a special NHS Swine Flu Hotline where a call centre worker will assess members of the public using a diagnosis algorithm which produces a diagnosis result based on the symptoms that are reported. If influenza is diagnosed then a voucher code is issued and a "flu friend" must be appointed to collect the Tamiflu from a regional collection point. The flu friend will require to have ID for themselves and the person for whom the medication has been prescribed. Apart from in a few isolated cases, Tamiflu has been shown to be effective in combatting this H1N1 strain of the influenza virus.

Is Tamiflu Suitable for you?

Certain people cannot take Tamiflu so it is essential that you complete a consultation form so that one of our doctors can assess whether or not it is suitable for you. If you experience an allergic reaction while on Tamiflu you should notify us or your own doctor straight away.

Tamiflu Side Effects

As with all medications, Tamiflu can produce side effects but these are not very common. The most common side effects reported have been: rash; nausea; vomiting and abdominal pain.

Tamiflu Prices

The MHRA has advised us that we cannot advertise the prices of prescription medications prior to a consultation with one of our doctors. We are confident that you will not be able to buy Tamiflu online cheaper so our general price match policy applies.
