Information on Xofluza: Dosage Facts, Strengths, Forms, and Timing Guidelines
Xofluza, also known as baloxavir marboxil, is a brand-name prescription medication approved by the Food and Drug Administration (FDA) for treating and preventing the flu. This article aims to provide a clear and straightforward guide on how to use Xofluza effectively and safely.
Firstly, it's essential to note that the dosage of Xofluza should always be as prescribed by your doctor. The dosages described in this article are typical dosages provided by the drug manufacturer, but individual requirements may vary. If you're having trouble reading your prescription label, don't hesitate to talk with your doctor or pharmacist. Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech.
Xofluza comes in two forms: oral tablets and oral suspension. The oral suspension must be taken within 10 hours after it's mixed by your pharmacist. It's important that you do not mix Xofluza oral suspension with any soft foods or liquids. To swallow the oral tablets, you should take them whole. If you have trouble swallowing tablets, you can talk with your doctor or pharmacist to find out whether they can prescribe the oral suspension for you instead.
To treat influenza (flu), Xofluza should be taken as a one-time dose within 48 hours of the beginning of your flu symptoms. For preventive purposes, it should be taken as a one-time dose after you've been in close contact with someone who has the flu.
It's crucial that you do not take more Xofluza than your doctor prescribes. If you take more than the recommended amount, call your doctor right away. Xofluza oral suspension will start working 4 hours after you take a dose, and it may take about 1 day sooner for people taking Xofluza as prescribed to have their flu symptoms resolve compared to people who don't take the drug.
If your flu symptoms aren't resolving or they're worsening after taking Xofluza, call your doctor right away. Your bottle of Xofluza oral suspension will have an expiration time marked on it to let you know the time it should be taken by.
Xofluza is generally more expensive compared to other influenza antivirals like Tamiflu and Relenza. While all these antivirals are effective when started early, cost considerations often influence prescribing and patient access. If you have questions about the dosage of Xofluza that's best for you, talk with your doctor.
Lastly, if you have additional questions about flu prevention, talk with your doctor. They can also discuss other preventive measures, such as receiving a flu vaccine. If you have any other questions related to Xofluza, talk with your doctor or pharmacist.
Remember, it's always best to follow your doctor's advice when using Xofluza. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room. In case of an overdose, seek immediate medical attention.
