I am 58 and have had the same problem for the better part of a decade: my BP goes up instead of down with almost all opioids/narcotics. More recently it has been suggested to me that a small number of people have or develop a type of allergic reaction to these meds rather than building up a tolerance. We (ie, my physicians) continue to look into it, but for practical purposes they have simply put me on tranquilizers. I know this is an old post, so I hope you have found some resolution to your problem.
Does high blood pressure run in your family? My father has high blood pressure and cholestro despite being an exercise-addict, healthy weight and not particularly old. I'll probably be the same. Some people are just unlucky.
I'm not 100% on this, but if you want to take co-codamol having high blood pressure is not listed as being contraindictive...so coedine being an opiate obviously isn't an issue there. To then apply that to all opiates might be a bit dangerous but based on that my assumption would be that opiates do not higher your blood pressure.
I'd have it checked into further. Your at a normal weight for your height, and your young. Also, have it checked again when the pain is at a more tolerable level. Pain does increase it, and can do so quite dramatically. If your readings are better with less pain, I'd say that was the culprit. Opiates tend to make blood pressure lower, unless your going through withdrawal. Have you thought about tapering off the opiates, and stopping for a while? Extended use causes your body to become dependant on the drug, and you need more and more of the drug to get relief. This is called tolerance. Then, your body actually causes the pain to get the drug. Stopping them for a while will tell you what your true pain level is. You will hurt more at first, until your body adjusts to not having the opiates. Many people find that their pain goes away, or can be managed with OTC medicines, heat, ice, massage, etc. I would think about this before trying the Sub, or Methadone. They are also opiates, and from what I've read here, are a killer to withdraw from. Good luck to you.
The only time that opiates tend to raise your bp is when you are going threw WDS
Sub is still a narcotic and it is not as effective (for me) as methadone for pain control. Do a lot of homework before you jump right into sub -
when your in pain your BP shoots up
Opiods generally lower your blood pressure. I think it is due to something else.
