I am heading for 70 and more and more I am querying the prescriptions my GP writes - and he is not a happy camper when I return the prescription saying I am no taking it because "..........".
These GPs only prescribe what they know or are paid by the chemical companies to hand out ... the pharmacists know a bit more, or go straight to the website of the chemical company and read the Consumer/Patient information.
It is our body and we have to be comfortable with what we shove into it ....
