Tamiflu (Actifed-P Cold) - is an oral anti-viral drug for the treatment of uncomplicated influenza in patients one year and older whose flu symptoms have not lasted more than two days. This product is approved to treat Type A and B influenza; however, the majority of patients included in the studies were infected with type A, the most common in the U.S. Efficacy of Tamiflu in the treatment of influenza in subjects with chronic cardiac disease and/or respiratory disease has not been established.

Tamiflu Basics

Tamiflu is a prescription antiviral medication that can be used to treat influenza infections (the flu) in children and adults, if their symptoms have started within the last day or two before starting to take Tamiflu. It can also be used to prevent the flu in children, teens and adults who have been exposed to the influenza virus.

What Tamiflu Is Used For

Tamiflu is approved to treat the flu in adults and children over age 12 months. It is also indicated as prophylaxis, or a preventative, against the flu for adults and children over age 12 months.

Tamiflu Side Effects

The most common side effects in pediatric patients taking Tamiflu for the treatment of the flu include vomiting, abdominal pain, epistaxis (nosebleeds), ear disorders, and conjunctivitis (pinkeye).

Tamiflu is being investigated under the Best Pharmaceuticals for Children Act, because in a safety review, 'unusual neurologic or psychiatric events such as delirium, hallucinations, confusion, abnormal behavior, convulsions, and encephalitis' were reported. However, the reports were almost all from children in Japan, where there were 12 deaths in pediatric patients, although the FDA 'can not conclude that there is a causal relationship between Tamiflu and the reported pediatric deaths.'

What You Need To Know

Tamiflu should be started as soon as possible after a child develops flu symptoms, and at least within two days, or as soon as possible after you have been exposed to someone with the flu, if you have not had a flu shot.
