Sorry to hear about this Kristi, but this is a great thread you started. A few observations: Xanax is in a family of medications called benzodiazapenes;they are intended to alleviate anxiety, not depression. Furthermore, some benzodiazapenes work fast, others, slower...the manner in which xanax works makes it easier for psychological dependence to set in. I can't explain it, but from what I have seen, if you looked in the medicine cabinets of 100 middle and upper class women, you would find 20-30 of those cabinets with a bottle of xanax. In my opinion, it is a terrible medication to use because of the addictive potential. There are other 'benzos' which are better choices for anxiety, and even then, I only write a prescription for them in small quantities, perhaps 5 pills for somebody going on a trip who is afraid of flying, for example.
Oxycontin is a whole other issue-obviously, it is a pain medication, and way too many people end up on the pills long enough to where they are physically and mentally dependent. With that said, it is easy to play 'armchair' physician and second guess well intended decisions...chronic pain is challenging for both the patient and the physician who desires to alleviate suffering. I think the best procedure when using this and similar meds is to draft a pain medication contract that the patient signs, stating that they will not have frequent refills, refills will be stopped if the patient makes no effort to attend physical therapy, not attempt to seek pain meds from a second source, etc.
As far as the antidepressant meds go, I think the SSRI meds such as Prozac are perhaps the third most useful categories of medication available behind antibiotics and cardiovascular medication. When used correctly, SSRIs can work near miracles in improving depression and helping people live better lives. I witnessed this first-hand in New Orleans after Katrina, perhaps the most depressed place in the country;I wonder what the suicide rate would be in the region had SSRIs not been available!?
Finally, all the above mentioned meds are available in generic form, so these are not the types of medications drug reps try to sell you on.
