Info on using mms 1 with metformin and losartan

I gave a friend some sodium chlorite and hcl along with Jim Humbles book. She takes metformin Hcl 1000 mg and losartan hctz 100 -25 mg. Is there any drug interaction with mms?
Asking doctor iss not in the plan. I am not on any prescription drugs , so I have no experience in this realm
Any suggestions would be appreciated
She lives in a big city and is worried about "coronavirus ",
