Why must baloxavir marboxil be used within 48 hours?

The CDC recommends that patients at risk of complications receive prescription antiviral treatment within 48 hours of symptom onset. Even for otherwise healthy individuals or those in high-risk groups, it is advised to use a single dose of baloxavir marboxil as early as possible during this golden window. This is because antiviral drugs need to intervene before the virus replicates extensively to achieve maximum effectiveness. Once beyond 48 hours, the drug's efficacy may diminish. When you or a family member experience sudden symptoms such as fever, body aches, or chills, do not hesitate to consult a doctor immediately and ask whether a single dose of baloxavir marboxil is appropriate for you. Timely treatment is key to overcoming the flu.

Three common symptoms of the flu

The flu is a rapidly escalating illness that can make you feel extremely unwell in a short time, and may even leave you with debilitating symptoms lasting more than a week. According to estimates from the U.S. Centers for Disease Control and Prevention (CDC), a single flu season has infected as many as 82 million people. Typical flu symptoms include fever, body aches, and chills. Of course, not every patient will experience all of these symptoms, but if you suspect you might have the flu, do not wait for your condition to worsen. Contact a doctor as soon as symptoms first appear. Ignoring the flu can lead to serious complications.

How to distinguish between the flu, COVID-19, and the common cold

Because some symptoms of the flu, COVID-19, and the common cold overlap, it is difficult for the average person to tell them apart. Generally, flu symptoms come on very suddenly, while cold symptoms develop more gradually. Fever is common in both the flu and COVID-19, but less common in the common cold. Body aches are common in the flu and COVID-19, but mild in the common cold. Chills and fatigue are common in the flu and COVID-19, but uncommon or absent in the common cold. Additionally, sneezing is common in the common cold, sometimes occurs with the flu, and is rare in COVID-19. New loss of taste or smell is a hallmark of COVID-19 and is rare in both the flu and the common cold. It is important to note that baloxavir marboxil is only indicated for treating the flu and cannot treat COVID-19.
