Out of country prescription refills

Basically, we have a 79yr old Canadian trapped with us. Risk of her returning to Canada wasn't the risk her family wanted to take. The only drawback of this, getting her prescriptions refilled. Her son didn't want to listen to me to call his doctor and explain and see if a local doctor can call in the prescription.

Does anyone know if there is an actual way for people out of country who are stuck here and need prescription refills to get this done without having to risk going to an actual doctor office? We've been strict with our stay at home due to her age and would prefer her not going anywhere still.

Thanks.
