Q: How does Xofluza work?

Mechanism of Action Xofluza belongs to a class of drugs known as polymerase acidic (PA) endonuclease inhibitors. It is designed to treat the influenza (flu) virus by interfering with its ability to make copies of itself. When the flu virus enters a human cell, it must replicate its genetic material to produce new virus particles. To do this, the virus uses a specific enzyme to "snatch" pieces of the host cell's genetic material. Xofluza binds to this enzyme and prevents it from functioning. By blocking this process, the medication stops the virus from replicating and spreading to other cells. This mechanism is different from some other antiviral treatments that work by preventing the virus from leaving a cell after it has already been created. Because Xofluza targets an earlier stage of the viral life cycle, it helps to: Reduce viral load: It lowers the total amount of the virus present in the body. Shorten symptom duration: By stopping the virus from spreading, it can help the body recover faster. Limit contagiousness: It may decrease the amount of time a person is able to spread the virus to others. Xofluza is effective against both influenza A and influenza B viruses. Because it targets the replication process, it is most effective when taken as soon as possible after symptoms appear, typically within the first 48 hours of illness.

Q: What are the active ingredients in Xofluza?

The active ingredient in Xofluza is baloxavir marboxil .

Q: What are the side effects of Xofluza?

Common side effects of Xofluza may include: diarrhea bronchitis nausea Always consult with a healthcare professional about potential side effects.

Q: What is the dosage of Xofluza and how do I take it?

How to Take Xofluza Xofluza is typically taken as a single dose by mouth. It is available as a tablet or as a liquid suspension. For the treatment of flu symptoms, the medication should be taken within 48 hours of the first signs of illness. For prevention, it should be taken as soon as possible after being exposed to someone with the flu. Administration Instructions You may take this medication with or without food. If you are taking the oral suspension, follow the specific mixing and administration instructions provided by your healthcare professional. Do not take Xofluza at the same time as dairy products, such as milk or yogurt, or calcium-fortified beverages. Avoid taking this medication with laxatives, antacids, or oral supplements that contain magnesium, aluminum, iron, calcium, or zinc, as these can interfere with how the drug is absorbed. Missed Dose Because Xofluza is administered as a single dose, there is no regular dosing schedule to follow. If you miss your scheduled dose, contact your healthcare provider to determine if it is still appropriate to take the medication based on when your symptoms started.

Q: Is Xofluza safe during pregnancy and breastfeeding?

Pregnancy There are no adequate and well-controlled studies regarding the use of Xofluza in pregnant women. While animal studies using high doses did not show evidence of harm to the developing fetus, it is not yet known if the medication is safe for use during human pregnancy. If you are pregnant or planning to become pregnant, talk to your healthcare provider about the potential risks and benefits. They can help you decide if this treatment is appropriate for your situation. Breastfeeding It is currently unknown if Xofluza passes into human breast milk, if it affects the breastfed infant, or if it impacts milk production. Research in animals has shown that the drug is present in the milk of lactating rats. Because of the lack of human data, you should discuss the risks and benefits of using Xofluza with your doctor if you are breastfeeding or planning to breastfeed.

Q: What is the FDA approval status of Xofluza?

FDA Approval and Indications Xofluza was first approved by the U.S. Food and Drug Administration (FDA) in 2018. It is a prescription antiviral drug indicated for the following uses: Treatment of acute uncomplicated influenza in patients 5 years of age and older who have been symptomatic for no more than 48 hours. Treatment of acute uncomplicated influenza in patients 5 years of age and older who are at high risk of developing influenza-related complications. Post-exposure prophylaxis (prevention) of influenza in patients 5 years of age and older following contact with an individual who has the flu. Regulatory Status and Safety Monitoring Xofluza is not a substitute for the annual flu vaccine. Regulatory agencies recommend the vaccine as the primary tool for preventing influenza infections. Xofluza is available only by prescription and is not currently approved for use in children under 5 years of age. There are no Boxed Warnings or Risk Evaluation and Mitigation Strategies (REMS) associated with Xofluza. The FDA continues to monitor the safety and efficacy of the medication through post-marketing surveillance and clinical data updates. Healthcare providers are encouraged to report any adverse events to the FDA MedWatch program to assist in ongoing safety evaluations.
