Tamiflu™ is a prescription antiviral medication used for the treatment and prevention of influenza symptoms. It is available in capsule and liquid form, and considered safe for adults and children over the age of one. Taking the recommended daily dose for a period of about ten days has been proven in clinical trials to alleviate symptoms and effectively eradicate the virus. Most people do not experience negative side effects, though nausea, vomiting, and abdominal pain have been reported. Allergic reactions are also possible, and an individual who experiences a severe skin rash after taking Tamiflu™ should stop using the medication and contact his or her physician immediately to receive treatment.

Tamiflu™ is the trade name for the drug oseltamivir. It works by restricting chemical bonds between cells infected by the flu virus and healthy cells, effectively preventing the virus from reproducing and spreading. Doctors usually prescribe Tamiflu™ to patients when they exhibit the first signs of flu, including chills, aches, and fatigue. The drug is most effective if it is taken within the first 48 hours of the onset of symptoms. In addition, the medication is often prescribed as a preventive measure for people who are at risk of catching the flu from family members.


Adults and children over the age of 13 are usually instructed to take one 75 mg dose of Tamiflu™ a day for up to ten days in the treatment or prevention of the flu. Younger children are typically prescribed 30 mg or 45 mg daily doses. The medication is available both in oral capsules and liquid form. Liquid Tamiflu™, which has a fruity flavor, is preferred by many children and adults who do not like swallowing pills. It is important to inform the physician of any other prescription or over-the-counter medications currently being used to prevent potentially adverse drug reactions. Patients should also tell their doctors about their medical history, especially if they have had kidney or liver problems in the past.

The potential side effects of Tamiflu™ include nausea, vomiting, abdominal pain, and diarrhea. If a person is found to be allergic to oseltamivir, he or she may experience a severe skin rash. In rare cases, the drug can cause mood changes and mental confusion that can lead to violent actions. An individual who notices any behavioral changes or a skin rash should immediately stop taking the drug. The prescribing physician should be contacted to conduct a thorough medical evaluation and recommend an alternative medication.
