Q: I am 57 years old and suffering from a knee problem. I have started taking Placentrex injections from India, in the hope of delaying osteoporosis. My knees make a creaking sound while climbing stairs. I was taking Glucosamine Sulphate for a year, but it hasn't been of much help. Please enlighten me on the pros and cons of this injection.

A:There is no evidence that Placentrex has any role in the prevention of osteoporosis. Glucosamine is not a medicine but Over The Counter (OTC) supplement. It does not reduce pain in osteoarthritis. One of its side effects is that it increases blood lipid levels.
