How does Tamiflu work?
Tamiflu, an antiviral drug, is used in the treatment and prophylaxis of both Influenza virus A and B. A neuraminidase inhibitor, Tamiflu acts as a transition-state analogue inhibitor of influenza neuraminidase, which helps in the prevention of new viruses emerging from infected cells. Tamiflu is the only neuraminidase inhibitor that has been proven to fight against Bird Flu.
Tamiflu was the first commercially developed, orally active neuraminidase inhibitor. Considered a pro-drug, Tamiflu is hydrolysed hepatically to active metabolite, the free carboxylate of oseltamivir.
Tamiflu is indicated for treatment and prevention in people at least one year of age and above. Reports are that Tamiflu may have an adverse effect on infants under the age of one.
Tamiflu Dosages
Tamiflu tablets are available as 75mg capsules and as a 12mg/ml tutti-frutti flavored oral suspension for children who are too young to swallow the pills. Tamiflu can be taken either with or without food. But, there are reduced chances of upset stomach if Tamiflu is taken with a light snack, milk, or a meal. In addition, this drug does not treat other flu-like viral infections, such as the stomach flu, colds, or RSV.
Tamiflu treatment should be started with the first appearance of the flu symptoms or soon after exposure to the flu. If one has the flu then Tamiflu must be taken twice a day for five days. But, if you want to take Tamiflu as a preventive medication against the flu, Tamiflu must be taken once a day for ten days. Tamiflu can be taken for up to six weeks. Do not take two doses at a time to make up for a missed dose.
Tamiflu precautions
Safety and effectiveness of Tamiflu have not been determined in people with chronic heart or lung disease, kidney failure, or in people with other underlying medical conditions. In addition:
Efficacy for Tamiflu has not been established in the treatment of flu-like illnesses caused by any virus other than influenza A and B (e.g., stomach flu, common cold, or other respiratory illnesses not caused by influenza).
Tamiflu is not known to work in other kinds of infections that appear like influenza or occur along with influenza, and need different types of treatment.
Taking Tamiflu should not affect an individual’s decision to have an annual influenza vaccination.
The safety and efficacy of repeated courses of Tamiflu treatment have not been established.
Tamiflu is not indicated for treatment or prevention of the flu in patients less than 1 year of age.
Tamiflu side effects
Vomiting, abdominal pain, epistaxis (nosebleeds), ear disorders, conjunctivitis (pinkeye) and nausea are the most common side effects of Tamiflu. Tamiflu side effects are mostly mild to moderate and are generally presented within the first two days of taking the medication. Sometimes, taking the medication on a full stomach may prevent these side effects.
Severe rash is another side effect of Tamiflu and the medication must be stopped in case this happens.
With Tamiflu, some people are at an increased risk of seizures, confusion, delirium, hallucinations, abnormal behavior, convulsions, and encephalitis.
In order to prevent side effects, it is also essential to tell your healthcare professional about receiving nasally administered influenza virus vaccine during the past two weeks.

What is influenza and how is it caused?
Influenza, also known as the flu, is a viral infection that primarily affects the respiratory tract. Its symptoms include fever, runny nose, stuffed up nose, fatigue, headache, cough, sore throat, vomiting, diarrhea, and achy muscles and joints. Not only is the flu contagious, it could become severe and even prove to be fatal if left untreated.
The flu is largely caused by three types of viruses, that is the influenza virus A, B and C. Type A is responsible for the deadly influenza pandemics while type B causes less significant, more localized outbreaks. Meanwhile, type C is less common and causes only mild symptoms. Capable of passing from person to person by airborne transmission (i.e., sneezing or coughing), the virus is also known to survive on objects for a short period of time. Therefore, influenza can spread through touch too. Moreover, the influenza virus can also spread by inhaling droplets that have been coughed or sneezed out by an infected person or by coming in direct contact with an infected person’s secretions.
Is Tamiflu an effective antiviral drug for Bird Flu?
Tamiflu (Oseltamivir) the drug in use, blocks the influenza virus from spreading between the body cells. As a consequence, this antiviral drug is used in the treatment and prophylaxis of both Influenza virus A and B infections. Oseltamivir, a neuraminidase inhibitor, first and foremost acts as a transition-state analogue inhibitor of influenza neuraminidase, preventing progeny versions from becoming detached from infected cells.
The first orally active neuraminidase inhibitor to be commercially developed, Tamiflu (Oseltamivir), is a prodrug that is hydrolysed hepatically to active metabolites. Developed by US-based Gilead Sciences and currently being marketed by Hoffmann–La Roche (Roche) under the trade name Tamiflu, this drug is generally available by prescription only.
Why Tamiflu?
It is essential to buy Tamiflu because:
It is recommended for use during infections with flu viruses A and B
It eases various ailments like weakness, cough, headache, fever, sore throat that accompany the flu affliction
It can prevent the onset of flu even when the patient has been exposed to the virus
Oseltamivir, a neuraminidase inhibitor, serves as an aggressive inhibitor for sialic acid that is found on the surface proteins of normal host cells; Tamiflu, in fact, prevents new viral particles from being released by infected cells.
