Long term effects of morphine on the brain (INFOGRAPHIC)

Morphine directly targets the central nervous system and changes the way in which the body feels and responds to pain. More precisely, it binds to opiate receptors in the brain and changes the neurochemical activity in the brain stem which can result in alteration of the automatic body functions. It also affects regions in the brain responsible for pleasure and with regular use the brain starts to register the effects of the morphine as a reward. Explore this infographic further for more details.

How long is “long term”?

I have been on these drugs for many,many yrs.I am now whining off all of them.Although I have done this before,on my own,I would never suggest,that anybody do that.I am now working with a professional team,to help me do that safely.It consists of my family doctor,a senior nurse,(which is trained in that field)plus a pharmacist.They are great,understanding,patient,wonderful,and I am grateful every day for there help.I would love to speak,about what it has caused in my life.Everything was in shambles.My health,family,friends,my mind(in many ways)& the list goes on.I had been asking my doctors,to get off these horrid meds,to hear,hoe r u going to control my chronic pain.In one month,I have regained my memory,balance,depression state is much better,constipation,confusion,psychotic behaviour,not caring about important things,not able to carry a conversation, lost my self esteem,balance,sleeping deprevation,although I was insomiac for yrs,things got much worse.Lucky to get8 to 10 hrs,in as many days as 5,& that happens very often.I am totally exausted most of the time,with reason.my sleep specialist could not understand why I was still alive,after all these yrs,without any decent sleep.I ask myself that same question????? Well the important point,is that I have turned it around&doing very well.Everybody is impressed wih my progress.I am not naive enough to think this is over,but relieved that it is the beginning of a whole new life,.one of quality,and one I am so much looking forward to.So far,the withdrawals have been really acceptable.I am on the road to wellness.I could say much more,but I would have to write a long book.If ever I can help someone,I would jump at opportunatly Good luck to everyone going through this bad scene.Hope this will be of help..

Just because I know how to spell( and use spell check) doesn’t make me spam! Notice you only have 1 comment.

My husband is an amputee and has all kind of back problems. He sees a pain management Doctor once a month to get his morphrine. He takes morphrine IR 15mg twice a day and morphrine ER 100mg twice a day. He is usually a easy going man but about once or twice a week he gets ANGRY or mad over the smallest thing and then we have a huge blow up. He has been taking this for about 6 years and since his amputation about 20 years ago has been on just about every pain med.

My question, is taking morphrine can it make you angry? He is also VERY forgetful but my main question can taking morphrine change your personality and make him mean? Thank you, Joan

Hi Joan. Morphine may have an impact person’s behavior. I suggest that you speak with your husband’s doctor about his behavior, and you may consider family counseling. Keep in mind that your husband has gone through very serious life situation, so maybe he needs counseling sessions on his own.
