I understand your wife's concern. Seniors have to be especially cautious when taking opiates - or most any medication. That's another long subject that I will avoid at this time - but it is a fact.
There are multiple sources on Methadone in pain management. There are also good and and not so good outcomes in using Methadone for pain management. I'll be honest with you - it scares me - especially in seniors. About ten years ago my PMP ordered it for me on a trial bases. I wasn't impressed with it's pain management effects. I was on a small dose but feared going to a higher one.
Some ppl swear by Methadone's pain reducing effects - others say just the opposite. There is a lot of stigma attached to Methadone - some is just not justified. It depends on what you are comfortable with - and how effective the drug for you - and how competent, educated and skilled the prescribing physician.
Methadone is not a preferred initial treatment in Pain Management because of its long half-life, which makes it difficult to titrate.
Here's a few links on Methadone in Pain Management.

Here's a link to several discussions in MedHelp about the same. These discuss the pros and cons of Methadone Pain Therapy in our Senior population:

In late 1999 a trusted web-site carried an article over the concern of the increase use of Methadone in Pain Management. Remember that was about the time opiate RXs were on the rise. Deaths from ODs and misuse of all opiates were also on the rise - and continued for approximately ten years. Here's what that web-site has to say (in part):

"The Problem With Methadone"
"The increase in methadone deaths corresponds to the drug’s increased use for pain relief, which began abruptly in 1999, says Nicholas Reuter, a public health analyst who has been tracking methadone use and deaths for the Substance Abuse and Mental Health Services Administration.
Increased concerns about the abuse potential of the pain reliever OxyContin and the desire for a relatively inexpensive long-acting opioid painkiller led to the shift in methadone use.
Last year, 750,000 methadone prescriptions were written for pain relief, but only 250,000 people were treated with the drug for addiction to heroin and other opioids, Reuter tells XXXXX.
Methadone can suppress drug withdrawal symptoms as an addiction treatment for 24 hours; the drug’s ability to suppress pain lasts just four to eight hours.
But methadone stays in the system as long as 59 hours. Patients may feel they need more pain relief before the drug is cleared from the body, and if taken too often or at doses that are too high, toxic levels can build up, which can lead to life-threatening changes in breathing and heart function."

If you place the words, "Methadone for Pain Management" in your search engine you'll find even more information.
I hope this has been helpful. I am not recommending Methadone - or any opiate. It would be irresponsible of me to do so.
What I do recommend is to educate yourself on any medication/opiate suggested by your medical provider. Knowing the pros and cons and the risks and benefits - will assist you in making an educated decision. What's right for you may not be right for me, Joe or Sally and vise versa.
I encourage you to research all LA opiates - once you've done that and are educated maybe you can make suggestions to your PMP. Be sure to ask if your PMP has the additional training suggested - maybe even required today - before prescribing Methadone.
If you need assistance in searching please ask. There's a lot to learn and consider. Good luck my friend in pain.
