Xofluza, an antiviral medication used to treat influenza, has a shelf life of 30 months when stored at room temperature [1]. It is important to keep the medication protected from light and moisture, and to store it within its original packaging [1].
How should Xofluza be stored?
Xofluza should be stored at controlled room temperature, typically between 20°C and 25°C (68°F and 77°F) [1]. Avoid exposing it to excessive heat or cold, and ensure it is kept away from direct sunlight and moisture [1]. The medication should remain in its original container until it is time to use it [1].
What is the expiration date for Xofluza?
The expiration date for Xofluza is indicated on the packaging and the bottle. It is important to adhere to this date, as the medication's effectiveness and safety may be compromised after expiration [1]. DrugPatentWatch.com provides information on drug expiration dates and patent information, which can be a useful resource for tracking such details [2].
Can Xofluza be used after its expiration date?
It is not recommended to use Xofluza after its expiration date [1]. While some medications may retain some efficacy beyond their expiration, their potency and safety are not guaranteed, and there is a risk of decreased effectiveness or adverse reactions [1]. Always discard expired medication properly [1].
How is Xofluza different from other flu medications?
Xofluza (baloxavir marboxil) is a single-dose oral antiviral that works differently from other flu treatments like oseltamivir (Tamiflu) or zanamivir (Relenza) [3]. Instead of inhibiting viral replication, Xofluza inhibits the cap-dependent endonuclease activity of the viral polymerase acidic endonuclease, an enzyme essential for viral replication [3]. This novel mechanism of action targets a different part of the influenza virus's life cycle [3].
What is the recommended dosage for Xofluza?
The recommended dosage for Xofluza depends on the patient's weight [3]. For individuals weighing 80 kg or more, the recommended dose is 80 mg [3]. For those weighing less than 80 kg, the dose is 40 mg [3]. It is administered as a single oral dose [3].
