This is true. If you can manage to get down to 150mg/day then you can just continue seeing the new doctor that is willing to prescribe you that. It's usually only when you taper down to lower doses that you feel bad withdrawals, but since 150mg isn't a low dose you should be alright, although uncomfortable for a short time. It's when you get below 40mg or so that it gets bad, or below 20mg if your tolerance had not been that high.
I know someone that takes over 300mg of oxycodone along with some morphine to get high for a few weeks from his script, and he gets by just fine on 60mg of oxycodone with 30mg of morphine as well.
So basically if you can get down to around 200mg you should be able to get by on the script for 150mg/day oxycodone instead of going the methadone or suboxone route. You can take more than prescribed for the first few days and then taper down to below 150mg to compensate for the extras that you took, but it's going to be a little rough.
Hey.
As stated, when you start tapering to incredibly low doses (double digits) that is when you will likely begin to suffer noticeable withdrawal symptoms as this tends to be the general trend with people on tremendously high doses such as you.
For example, I know a patient who was happy on 600mg of Oxycodone a day, cut down to 300mg, bit more pain, nothing much. Cut down to 100mg, bit more pain and a bit jittery, but that went away after a week or two.
This patient even dropped down to 40mg and all adverse effects (besides a tad bit more pain) settled down within a fortnight.
However, as my pain consultant and I have discussed, in almost all people taking a strong opiate, there is a level at which most people find it completely intolerable to drop lower than. For this patient it was 40mg. If he dropped to even 35mg his pain SKYROCKETED and suffered all types of withdrawal symptoms. Once you reach that level is when the serious withdrawals start. This is why tapering is called tapering. With that patient, they got to 40mg, stopped and then transferred him to 10mg methadone for a few weeks and then continued his care.
However, with yourself, going from 700mg --> 150mg will be fine, especially if you take TommyBoy's recommendation and cut down to ~200mg a day, given your medication I would suggest:
2x 85mg Oxycodone MR (One every TWELVE hours).
1x 30mg Oxycodone IR. Figure out when your pain tends to be at it's worst and take it then, or take it before bed to help you sleep.
If you can get to that level, then moving down to 150mg should be, essentially, no sweat for you. For you taper, I would recommend:
Day 1: Full 700mg as normal.
Day 3: Cut down to 4x 85mg Oxycodone MR + 3x 30mg Oxycodone IR. This is 430mg.
Day 7: Cut down to the above level, roughly ~200mg a day.
That should give your body adequate time to adjust, you could do it all in one go but if you taper it as above it should give you an easier ride, make sure not to worry. If you worry excessively you'll just make it worse. Keep yourself busy to keep your mind off the increased pain level and I guess that you're probably going to be A-Okay.
As for the post below me, Cloudy likely means
hyperalgesia. This means that on your lower doses as you taper, you will find not only will your pain level increase slightly, but you will find yourself hypersensitive to other forms of pain, such as pricking yourself on a pin, standing on a plug or accidentally touching something hot. This may happen, it may not.
Reducing your opioid load as soon as possible is a good idea, it reduces the risk of nasty side effects such as opioid-induced hyperalgesia and (more rarely) allodynia.
My final note, and this is very important as it is a crux of most pain management programmes is as follows:
"The most effective dosage of analgesics is the LOWEST DOSE POSSIBLE that makes your pain TOLERABLE so that you can function as NORMALLY AS POSSIBLE".
Make sure you discuss this with your new Doctor because, as the quote above says, you may be able to do just fine on 100mg of Oxycodone daily, if that is the case, you do not want to be on ~200mg a day, ask if the both of you can work out a programme to achieve the best pain relief you can for the lowest dose, it will likely be helpful in the long run.
As for opioid-induced hyperalgesia, what Cloudy is talking about, I doubt that is much of an issue here. Most people with OIH tend to be in severe pain, far beyond their original pain levels and the only thing that helps is cutting down on medication significantly. Given the fact that you haven't mentioned anything about a lower dose helping or whether your pain levels are increasing I doubt that is going to be much of a factor here, your pain will increase when you cut down, guaranteed, but that won't be OIH as if you were suffering from OIH your pain would decrease when you cut down, if that is the case, just mention it to your new Doctor.
Also, why not try alternative pain management methods? There are plenty out there, such as:
Losing weight.
Trying to do light exercise, "get fitter" for lack of a better phrase.
Massage/sports massage.
Rub-in anti-inflammatory creams.
Cold sprays, such as Deep Freeze type stuff.
Acupuncture, it works FANTASTICALLY for some people, so definitely worth trying!
What I am trying to get across is that, especially nowadays, people in pain just want to pop to the Doctors, ask for a pill and hope it will go away instantly, whilst this is doable for most people and great that we can do it nowadays, there are other ways to try, don't just rely on your medication, there are other pain control methods.
Cheers!
