Genetics is really a hot topic in medicine and science right now, and for good reason. We are each unique, in part due to our inherited DNA. Different people can respond differently to the same medication based on their genetic make-up, yet we are just now starting to appreciate this.
I think genetics is a significant factor in understanding a person's pain and in their response to certain pain medications. Researchers are just now starting to find genetic links to problems like degenerative disc disease. As we learn more, I think we will find significant variation in how patients respond to medications based on not only their genetic code, but also on what environmental factors turn these genes on or off.
While we don't yet have the ability to understand how your genes affects the way you respond to Methadone, there are some things for you to consider. There are risks associated with the use of high dose Methadone that you should talk to your doctor about if you are still on it. You seem to have a high tolerance to opioids which may impact your response to any opioid medication. There is also a phenomenon that we have discussed in the past known as opioid-induced hyperalgesia, where the person gets more and more sensitive to pain after being on opioids over time.
These are just a few of the factors that can influence the way your medications may be effecting you.
