Is Flucloxacillin available in the US?

Excuse me, I was wondering if you could provide some clarity on the availability of Flucloxacillin in the United States? I've been told it's a highly effective antibiotic for certain infections, but I'm not sure if it's accessible here. Could you please shed some light on whether Flucloxacillin is readily available for purchase or prescription in the US, and if there are any potential alternatives if it's not? Thank you for your assistance.
