There is an excellent article I just read on this subject, one that everyone should read, consider wisely and take charge of their own health. Too often drugs are prescribed without the patient being aware not only of the potential side effects, but of the actual benefit, nominal benefit or lack of benefit that these medications prescribe.
I am not a doctor, nor do I profess to be. However, I am a firm believer in taking a pro-active role in our own health and weighing all options before making an informed decision.
Read this article, it is long but very informative!
