As a doctor training in infectious diseases, I knew that the flu can be dangerous in vulnerable populations like little babies. I had visions of Joe being admitted to the pediatric intensive care unit, as I swallowed a pill of oseltamivir (brand name “Tamiflu”) and shivered under the covers.
Should I also give my little boy Tamiflu to prevent him from getting sick? The answer should be clear to an infectious disease physician-in-training, right?
I felt competing instincts. Paternal: to “do something” to prevent Joe from getting the flu. Medical: “do nothing,” as the rampant overuse of antibiotics in children has had negative consequences and the same might be true for antivirals.
As I researched the question further, I learned that the decision to give prophylactic Tamiflu is anything but simple.
Close contacts of people with the flu (including babies) can receive Tamiflu if they are at high risk for influenza complications. One Greek study of 13 newborns found that the drug was safe but did not address its effectiveness. Moreover, the number of babies who would need to receive Tamiflu to prevent one serious case of influenza is unknown.
