Chinese generic medicines and fake/counterfeit drug dangers

this is a big problem here: generics are cheaper but you don't know if they work.

Usually, if it is a major infection or something important, I buy brand names or brand name generics at Mercury drug store, which checks on their generics.

The cheaper generics? I use when not so important.

Once Lolo had an infection that didn't get better with generic cephalexin, and our niece said to get the brand name, and the infection promptly resolved. Since he had CLL and a poor immune system, this could have mean a life threatening infection: but the generic was not completely fake, so it merely kept the infection under control with a suboptimal dosage.
