What is Oseltamivir (Tamiflu) and Zanamivir (Relenza)?

Zanamivir may worsen asthma or chronic obstructive pulmonary disease (COPD). Some kinds of seasonal influenza virus are resistant to oseltamivir in the US. The FDA repeated its warning of possible adverse effects in patients, especially children, taking oseltamivir. In some cases, these effects (such as hallucinations, delirium, and abnormal behavior) resulted in injury and death.
