Resistance forces new flu medicines on the market



RENO, Nevada (KOLO) Tamiflu was approved for the US market almost 20 years ago.
The antiviral virus was applied twice daily for five days to prevent the symptoms of the flu.

With few side effects and recommendations for children 12 months and over, this was considered by many to be a godsend.

But viruses are tricky.

"Resistance peaked with the H1N1 outbreak in 2009. We saw a lot of resistance to Tamiflu," said Jennifer Wheeler, pharmaceutical director of the Community Health Alliance.

With influenza resistance to Tamiflu Recently, the FDA approved a new flu medication called Xofluza. While the symptom relief in Tamiflu and Tamiflu is quite similar, there are some differences day for five days.
Xofluza is a single dose drug. The two medications must be taken within 48 hours of the onset of the flu symptoms, and you need a prescription.

Xofluza acts like Tamiflu by preventing the virus from replicating. However, this new drug breaks the chain faster, which means that patients taking Xofluza have the likelihood that they will not spread the disease to others.

Xofluza is recommended for children over 1

2 years and adults. It is not recommended for high risk patients, who are 65 or older, or who suffer from bronchitis or pneumonia. However, a recent study published this month showed that the drug is effective in this group of patients compared to placebo.

Without insurance, Xofluza costs $ 180, while a generic Tamiflu costs just over $ 150. Insurance companies may want to pay for the cheaper drugs.

Most pharmacies we talked to are fully stocked with Tamiflu.
This new drug is not on the shelves yet. It could be on the market in the next few weeks.
