Question 1

What is Xofluza?

Accepted Answer

Xofluza is a prescription antiviral medicine designed to combat the influenza virus, commonly known as the flu. It belongs to a class of drugs that interfere with the virus's ability to replicate within the body.

This medication works by blocking a specific protein that the flu virus requires to make copies of itself. By inhibiting this process, the medicine helps limit the spread of the virus throughout the respiratory system.

Question 2

What is Xofluza used for?

Accepted Answer

Xofluza is used to treat influenza.

Question 3

How does Xofluza work?

Accepted Answer

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.

Question 4

Question 5

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.

Question 6

What drug class is Xofluza?

Accepted Answer

Xofluza belongs to the antiviral drug class.

Question 7

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

Accepted Answer

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.

Question 8

Is Xofluza safe during pregnancy and breastfeeding?

Accepted Answer

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.

Question 9

What forms and strengths does Xofluza come in?

Accepted Answer

Xofluza is supplied in two primary oral formats for patients:

Tablets: These are solid oral tablets intended to be swallowed whole.

Granules for Oral Suspension: This version comes as granules that are mixed with water to create a liquid mixture before administration.

Question 10

What is the FDA approval status of Xofluza?

Accepted Answer

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.

Question 11

What should I know about Xofluza and cost?

Accepted Answer

Factors Influencing Cost

The price you pay for Xofluza can be affected by several variables:

Insurance Coverage: Many commercial insurance plans and Medicare Part D cover Xofluza, but your specific out-of-pocket cost will depend on your plan's formulary and deductible status.

Pharmacy Selection: Retail prices can vary between different pharmacy chains and independent drugstores.

Dosage: Xofluza is typically administered as a single dose, but the cost may vary depending on the specific strength (such as 40 mg or 80 mg) required based on your weight.

Financial Assistance

Because Xofluza is a brand-name medication, the manufacturer may offer a savings card or coupon for eligible patients with commercial insurance. These programs are designed to reduce the copay amount. Patients without insurance may need to explore patient assistance programs or use pharmacy discount cards to lower the retail price.

Generic Availability

At this time, there is no generic version of baloxavir marboxil available. Brand-name medications like Xofluza generally cost more than generic antiviral alternatives, such as oseltamivir, because they are still under patent protection.
