Treatments and drugs

By Mayo Clinic Staff

Medications

Many influenza viruses have become resistant to the effects of a category of antiviral drugs that includes amantadine and rimantadine. Health officials recommend the use of oseltamivir (Tamiflu) and possibly zanamivir (Relenza) instead.

These drugs must be taken within two days after the appearance of symptoms, something that may prove logistically difficult on a worldwide scale, even if there were enough to go around. Because they're in short supply, it's not entirely clear how flu drugs would be allocated if there were a widespread epidemic.
