Yes. Insurance may not pay, though. Many compounding pharmacies carry it.
FYI, I talked to a pharmacist, here in California and he said they were not allowed to dispense HCQ unless it was part of a trial.
I then contacted my doc's office and now have some coming from a compounder. They are dispensing 10 doses only. So the idea is to only take it if I test positive for Covid in the future. It's not for prophylaxis.
YMMV
