Xofluza Tablets
Xofluza is an antiviral medication used to treat and prevent influenza (flu). It works by blocking an enzyme called polymerase acidic (PA) endonuclease, which the flu virus needs to replicate. By stopping the virus from multiplying, Xofluza helps reduce the severity and duration of flu symptoms when taken within 48 hours of onset. It is available as a single-dose tablet.
- Used as both treatment and prevention of the seasonal flu
- Effective against both influenza A and B viruses
- Most effective when taken within 48 hours of symptom onset
- Dosing is based on weight and is typically administered as a single dose, with or without food

Xofluza Tablets Medication Description
Xofluza (baloxavir marboxil) is a novel antiviral agent designed to combat influenza by targeting a unique mechanism in the virus’s replication cycle. Unlike traditional neuraminidase inhibitors like oseltamivir, Xofluza inhibits the polymerase acidic (PA) endonuclease enzyme, which is essential for viral RNA transcription. This action halts the virus’s ability to multiply, thereby reducing the viral load and shortening the duration of symptoms. Approved by the FDA in 2018, Xofluza is indicated for both treatment and post-exposure prophylaxis of influenza. It is particularly useful in high-risk populations, such as the elderly or those with chronic conditions, who are more susceptible to flu-related complications. The single-dose regimen improves adherence and convenience, making it a valuable option during flu season. However, clinicians should consider local resistance patterns and emerging viral strains when prescribing Xofluza, as its effectiveness may vary depending on circulating influenza types. -
Xofluza Tablets Side Effects
Xofluza is generally well tolerated, but like all medications, it may cause side effects. The most commonly reported adverse effects include diarrhea, bronchitis, headache, and nausea. These are usually mild and resolve without intervention. Rare but serious reactions such as hypersensitivity (rash, swelling, or difficulty breathing) may occur and require immediate medical attention. Patients should also be aware of the potential for viral resistance, especially in children and those with weakened immune systems. It’s important to monitor for worsening symptoms or new signs of infection and to consult a healthcare provider promptly if concerns arise. -
