Conversion From Opana Er 15mg To Ms Contin

My Dr has given me the option to switch from Opana ER 45mg to msCottin ER!
How many MG of MSCottin ER will it take to equale the Opana ER 45mg??

Hello, Sharon! How are you?

Opana is actually much stronger than Morphine, so you'd need 135mgs of the MS Contin to equal each 45mgs of the Opana. That's quite a lot to take.

Is the Opana no longer working for you?

This is a narcotic analgesic, so it has the potential to be habit forming and may cause side effects, such as nausea, dizziness, drowsiness, dry mouth and constipation.

Oxycontin or Fentanyl might be better options.

Thank you for the information. It's helped a lot!
I am switching medications because of several different stomach problems I have. About 10 years ago I had gastric bypass surgery that went horribly wrong. Nothing healed correctly from the surgery! They even punctured my esophagus which led to an abscess that formed & puts pressure on my diaphragm! That causes me to have residual chronic pain on my shoulder and upper arm! I also have chronic back pain in my upper and lower back. I've had several bleeding ulcers in the past few years. I am not allowed to take NSAIDs of any sort. That leaves me very limited on what I can take. The Opana worked very well for me! Unfortunately since I had gastric bypass surgery my digestive system passes things very quickly. Opana was one of the things I was passing almost as soon as I take it (not all the time, but often enough). My doctor recommended me to start on the MS Contin and said that it may work better in my system and not pass it like I would be w/the Opana!

It's been incredible what that surgery has done to my life! To put it mildly I've been to hell and back over the last 10 years. I am now permanently disabled due to having that surgery done. I can no longer eat solid food! I literally live on watery scrambled eggs, yogurt, ice cream and occasionally broth!

Wow, Sharon! You have been through a lot and I am so very sorry, that's terrible.

I actually have a better idea that you may want to ask your doctor about. There is a patch available under the trade name Duragesic, but also as a generic, which contains the narcotic Fentanyl, it's very potent and, since it's a patch worn on the skin, you'd not have to worry about your GI system passing it through too fast and not absorbing it.

This is a narcotic analgesic, so it has the potential to be habit forming and may cause side effects, such as nausea, dizziness, drowsiness, dry mouth and constipation.

The patch is worn for 3 days, during which the medication is slowly released.

Are there any other questions or concerns?

Can anyone tell me what to do?
