Medication and loss of cognitive abilities

I have recently started taking Kapanol (morphine) for chronic pain following an injury at work. I am getting extremely frustrated at the effect it has had on my intelligence! I have always been quite intelligent, with a broad vocabulary, but since starting on this medication I feel like I can barely string a sentence together. I find that I can't remember words that used to come easily. I can't write posts like this without struggling to find the right words and trying to make the thoughts come out in some kind of order. I hate the fact that to ease my great pain, I also have to give up some brain power. Does anybody else out there have the same problem? Has anybody come out the other side and got back to normal? It worries me that I could be killing off brain cells.

How long have you been on the Kapanol? Your body will need a couple of weeks to get used to it before you can say if the side effects are intolerable. Do you feel as if the dose is too high? First think of your pain. Has it improved on the medication? They usually have you rate it on a scale of 1-10, with 1 being no pain and 10 being intolerable pain. How does your pain rate now compared to when you started it? Do you feel doped up and sleepy? Are your thoughts clouded all of the time? What about your speach and coordination? You might want to consider these things and discuss them with your doctor. Maybe the dose can be decreased a little bit. There's also a chance that you aren't tolerating morphine.Many people cannot take morphine, but they do well with another long-acting opiate. The key is to find something that relieves your pain so that you can live a normal life, but that doesn't have intolerable side effects. You don't want to be pain-free and end up in a stupor all day long! Give it enough time to get used to- maybe a week or two. If you're still bothered by this, talk with your doctor and ask that he consider another alternative. I have had many patients with chronic pain, and it's amazing how these medications affect each person in different ways. Sometimes it is a trial and error period before we find a medication that relieves pain and causes a minimum of side effects.

I've been on it for about 10 days or so, so I guess it might take a bit longer. As for the dosage, I don't think it is quite enough. My doctor has advised me to try one week at each dosage, and then increase if necessary. I started on 10mg in the morning and 10mg at night, now I am on 20 and 10, and in a week I will most likely go up to 20 and 20. The pain just isn't being controlled. I do feel very sleepy, but I am slowly getting past this. I tend to have a sleepy day every other day. My speech and coordination are okay - I just feel as though my brain is only firing on 4 cylinders. You could be right about not tolerating the morphine. I was on Norspan patches before I went on to the Kapanol, but I had to stop those due to an allergic reaction - I got itchy red welts at the site of the patch. I know it is a trial and error thing. I am actually booked into a specialist to see if surgery will help the pain. I've always had an aversion to surgery, but then I've never been in this kind of pain before. Now I am just hoping to get rid of the pain. I'll stick with the Kapanol a while longer, and if the problems continue I will speak to my doctor again.
