My wife used one or two mail-order Canadian pharmacies. Saved money and there were no problems. You might want to make sure you know where the drugs being sold were actually made. I wouldn’t worry about drugs made in Canada, India I might take a pass on.
What are these companies?
We have prescription coverage through California PERS (Blue Cross and Optum RX). Every single one of the prescriptions from Optum that we get is made in India.
India has a very advanced chemical industry and is actually a good source for labor-intensive chemicals like prescription drugs.
I have no qualms about Indian drugs, and I am a chemical engineer.
