Over the past 2 decades I've been trying various medications to help me w/ my long running major depression & crippling ADHD. And none have seemed to work.
Recently, the doctor I'm working w/ nowadays suggested that she's practically running out of options to offer me & that I should take a pharmacogenetics test to help her figure out what should she prescribe.
I took the (expensive) test and the results were eye-opening! The results came out a couple of weeks later w/ a detailed list of some few hundreds medications of various sorts (from pain killers to blood pressure control) along w/ their efficacy for my case. The physician's version also included a list of suggestions and alternatives for each medicine.
In my particular case, it essentially indicated that any medication that I had tried before was supposed to be either useless or to have limited impact on my body. That part is true.
Please note that I've only started a new set of prescriptions since a couple of weeks ago and as such can't really vouch for the accuracy of the suggestions.
I struggled a lot w/ myself to post something this personal. But I thought maybe there are people out there who've got no idea such tests exist and it might turn out to be helpful to some.
A few years back during a grueling med search I pestered my shrink for a CYP2D6 genetic test and sure enough I'm a non-metabolizer ... it's played into a number of med decisions since then.
