ULPT Visiting the US, forgot bloodthinner, help me get my rx meds fast

I’m visiting the US for 10 days, I’m a citizen but live abroad, landed yesterday and realized I forgot to bring my blood thinner medication. I tried to get a virtual appointment at the CVS Minute clinic and I can’t afford it. I called another clinic and they said I would need a bunch of medical tests before they could prescribe anything so they couldn’t help me.

I only need 8 days worth before I go home. But I haven’t found a way to get the rivaroxoban. I’m afraid to continue the 8 days without it though because I’ve had several clots in my lungs and many clots in my legs before I was on the medicine.

Please give me some ideas. Thx
