all you had to do was type "opiate conversion" in the search box and this is the first link.

Opana is oxymorphone. That

Opana is oxymorphone.

That seems like one huge leap, from meperidine to oxymorphone. I am assuming you are taking the demerol orally? What is your daily dose?

Orally, meperidine is pretty weak, and on top of that, it causes far less respiratory depression than opiates and semi-synthetics.

I am not you doctor, but it sounds like you should be on at least hydrocodone before switching to oxymorphone, just so there is less of a chance that you will have respiratory depression. The conversion chart will give you the estimated ANALGESIC equivalent, but won't come close to the equivalent dose for the same degree of respiratory depression.

Would 20 mg of oxymorphone a day kill you? Doubtful. But it would still be a smoother transition if you were not going from a "weak", "light" narcotic, to a very potent, "heavy" narcotic.

(Yes, oxymorphone is not very bioactive via oral admin, but it is still much more potent, both quantitatively and qualitatively, when both are administered orally.)

Just watch your respiration (breathing)

If you start to have difficulty breathing, go to the ER right away. He is right that that is a HUGE step. Be careful

Everyone keeps saying it is

Everyone keeps saying it is a huge step but he never said what mg he takes of the demerol now so if he was on a huge amount then 5 or 10mg opana would be equal. I still think you should have at least tried hydrocodone or oxycodone before going to the extended release meds but if he is getting equivalent dose of his current demerol in opana then there shouldn't be problems. you cant say its a huge step without knowing how much demerol he was on cause he could have been on abnormally high doses of that. 109 mg demerol equals 5mg opana if my calculations are correct. I am unaware what mg pills demerol comes in though.

It is odd that demerol is a sch2 while hydrocodone is a sch 3

Wow, i really didn't know

Wow, i really didn't know that. Isn't demerol weaker than hydrocodone? or it might have something to do with the fact that demerol has no tylenol because hydrocodone without tylenol is a schedule II

I am glad to hear someone

I am glad to hear someone else pointing out that one narcotic is not stronger than another unless you also know the dosage.

The daily limit for

The daily limit for meperidine is 600mg, and that is not to say this is safe.  You run the risk of potentially serious anticholinergic effects, similar to those of atropine toxicity when the active metabolite (norpethidine/meperidine) accumulates.

 This is not to say that the doctor is not rxing above the recommended daily limit.  I agree that without knowing the dose, nobody can say for sure what should be recommended, but speculation can be used here.

And again, you can quote a narcotics conversion chart all day, but no matter how you look at it, you will not see a conversion based on the risk for respiratory depression.  Analgesia is not the issue I have a problem with.  We arent talking about switching to a codone, it is a morphone, which is arguably the most likely oral narcotic to cause serious respiratory depression.  The only other drugs that compare are hydromorphone, and methadone, both of which would be quite the leap from the narcotic that is probably the least likely to cause respiratory depression. I have read more reports of Propoxyphene causing breathing problems than I have Demerol.
